For complete details on which models support which features, see our feature comparison table below.

With all of these features, the Radiance  provides much of what you get from a high-end home theater receiver without the amplification digital sound decoding. However, what makes the Radiance truly special is the full set of video calibration controls it also offers.

The Radiance is the best way, and in some cases the only way, to achieve an optimal theater setup.

 

Radiance Overview

Boasting multiple video and audio input options, the Radiance functions as an extensive central switching hub, providing home theater system video quality that will satisfy the most demanding enthusiast.

The HDMI inputs accept resolutions of up to 4K UltraHD (2160p at 60 Hz). Component inputs accept resolutions of up to 1080p at 60Hz.  Audio input can accompany the video on one of the HDMI inputs, or use analog stereo pairs, coax or optical audio inputs. Component inputs can be combined with a composite to support SCART RGBcvS video sources.

The HDMI outputs can be a copy of the first output, or they can be used as an audio only output to send audio to receivers that do not support 1080p60 or 4K UltraHD for their HDMI inputs. Audio output is supported on the HDMI connections plus COAX audio outputs.

Radiance models include integrated Darbee DVP™ image enhancement technology.

All Radiance models include setup and calibration features include multi-point linear-Gamma RGB color palette CMS (up to 4913 points), 21-point parametric gray-scale and Gamma, a host of setup features, Lumagen’s industry leading No-Ring™ scaling technology, and support for 3D scaling and conversion between 3D formats for displays and projectors that do not support all the common 3D formats.

The Radiance offers 10-bit on the front end and 12+ bit processing in the calibration pipeline, including per-pixel standard definition (SD) and high definition (HD/UltraHD) video de-interlacing with adaptive diagonal filtering, edge enhancing scaling technology that does not add ringing (unlike competing products), plus MPEG mosquito and block artifact reduction. Finally, an important image quality feature is temporal noise reduction for both SD and HD/UltraHD sources.

Other Radiance key features include user-adjustable image enhancement, including four configuration memories for each input, a programmable output resolution from 480p to 2160p, plus 1080i; the ability to zoom in on any source by up to 33 percent; selectable aspect ratios of 4:3, 4:3 NLS, 16:9, 1.85, and 2.35. The 4:3 NLS aspect ratio uses Lumagen’s Preciseview user programmable non-linear-stretch mode to allow the user to program exactly how 4:3 sources fill a 16:9 display. For film sources 2:2, 3:2 and 3:3 pull-down detection is supported to allow for correct cadence output at 24, 48, 60 and 72 Hertz for 24 fps film sources, plus 50 and 75 Hertz for 25 fps film source.

Complete 3D processing: The Radiance with HDMI 1.4 and/or HDMI 2.0 actually processes the 3D, and does not just pass through 3D like other scalers such as the DVDO Duo. The Radiance can scale, crop and calibrate your 3D sources (Blu-ray, PS4/PS5, etc).

 

Radiance Upgradability

Lumagen over the years has kept up with new features and offered upgrades to existing users more so than any other  manufacturer - often through completely free software upgrades. Most other companies we know of do not do this. Instead, they make you buy a new model as new features are introduced. The Radiance is completely over engineered with processing power that has proven that it can take on just about anything.  

A standard feature of all of the Lumagen video processors is the use of a FPGA (Field Programmable Gate Array). This allows Lumagen to add new features by reconfiguring the hardware connections inside the video processor. This is in addition to the normal software update for the microprocessor. This is what makes the Lumagen Radiance video processor a better value than the competition. They have the ability to add major new features, such as support for 3D video which was added for free when it first became available.

The new modular I/O technology on the Radiance Pro series takes this one step further and allows upgrading to new HDMI technology as it becomes available (such as 18 Ghz / HDR support).

Truly phenomenal support from Jim Peterson and his crew.

 

Darbee Visual Presence™ (DVP™) technology

Now available: Darbee Visual Presence™ technology provides an exceptional increase in depth and detail for all display types on a per-input basis (allowing you to use different amounts of enhancement per source). The better and more detailed your source signal is, the better the resulting picture will be. For complete details visit our Darbee page.

 

Advanced Greyscale, Gamma, and Colour Management System (CMS)

Until now there was always one weak link in the chain of video calibration. If your display lacked the proper set of calibration controls, it simply didn't matter if you had an extremely accurate meter and the world's greatest software. Without the means to adjust the image, you could not improve the display regardless of the calibration equipment you used.

The solution to this problem is the Radiance that provides the necessary adjustments that you could place in between the source material (broadcast, DVD, or Blu-ray) and the display. Up to 4913 points of automatic calibration are available, ensuring the most accurate picture possible.

The Radiance includes an advanced Greyscale, Gamma, and Colour Management System (CMS), including:

  • Comprehensive set of video test patterns.
  • 5% or 10% grayscale/gamma adjustment.
  • Full 3D color management, offering adjustments to the brightness, hue, and saturation of all of the primary and secondary colors.
  • An advanced multi-point CMS (up to 4913 points) for extremely accurate colour correction and calibration (read more)

These may be adjusted manually or by using ChromaPure Advanced Auto-Calibrate which allows anyone with little or no training in video technology to fully calibrate their display with almost no user input. Just setup a few simple options, click Auto-Calibrate, and then just go have a cup of coffee while the process completes, usually in less than 10 minutes.

The Radiance is more powerful than the iScan Duo. It offers more test patterns and provides the option to perform grayscale and gamma calibration in 5% or 10% increments as well as (up to) 4913 point autocalibration instead of only 6 point. The Radiance also outputs true 3D signals, so it is ideal for calibrating displays in 3D mode.

Add ChromaPure video calibration software with the auto-calibrate add-on and a high quality color analyzer, such as the Display 3 PRO and you have the ability to achieve professional-quality results with no training or expertise in video calibration.

 

Why do I need a Colour Management System (CMS)?

Most new displays today artificially boost or shift how they create colours (especially green and blue) in order to boost light output and to make the colours appear more 'vivid' or 'pleasing' to the consumer. What's important to know is that this is completely incorrect and is not what the director intended for you to see. It results in incorrectly oversaturated colours causing (for example) faces to glow pink or grass to have neon-like glow to it as seen below:

This is not something that affects only cheaper or incorrectly manufactured displays. Displays at all price ranges are affected, from PC monitors to expensive high-end home theater projectors like the JVC shown above. The only way to fix these deficiencies on displays such as these that do not include a CMS is by using a video processor like the Radiance.

There is a lot of confusion on the market today as to how various products approach doing CMS. The Lumagen Radiance is currently the ONLY consumer video processor that uses a true Linear-Gamma 3D Color Palette (3D LUT) for CMS. (A 3D Look-Up-Table (LUT) maps the source video to a specific color palette on the display and so is often called a 3D color palette).

Other consumer video processors do not provide a 3D LUT. Most use a HLS Color/Hue control and calls it a CMS. All HLS “CMS” systems are mathematically incorrect and results in non-linear response when used for calibration.

Manufacturers might call their solution a “3D CMS” or a “6-axis” CMS, but it is not a 3D LUT. Every CMS (by definition) must be a “3D CMS” since there are three primaries and so it is at least 3 dimensions. "3D CMS" is a meaningless marketing term used by some manufacturers.

For more information on why proper colour calibration is critical to proper movie reproduction, see our extensive ChromaPure Grayscale & Color Calibration for Dummies guide. Learn how to get the best image quality out of any display and more importantly, how to do it yourself.

 

What's the difference between 9Ghz and 18Ghz?

Choose 18Ghz inputs if you want to support HDR10 and HLG from sources like the AppleTV 4K. These require an 18GHz input for HDR support. With the Pro's excellent output dither many do not see any technical reason to have an 18GHz output. For 4k24 HDR there is no difference since both 9G and 18G support 4:2:2 12-bit. For 4k60, a 9 GHz output is 4:2:0 at 8-bits, and a 18 GHz output is 4:2:2 at 12-bits. The only real question is can someone perceive an improvement using an 18G output for a 4k60 HDR10 source. In A/B comparisons we do not see any difference between the 9G and 18G outputs even on tough HDR scenes running at 4k60. So if you're looking for the lowest cost of entry with HDR support, choose the lowest cost Radiance Pro and upgrade one input card to 18G such as the "+" models. For those who want full 18 Ghz all around then the "-18G" models are the best option.

 

Can I add extra input cards to my Radiance Pro?

Yes. The 444X chassis are built to accept up to 8 inputs, the 424X chassis are built to accept up to 4 inputs. Exceptions include the 4244 and 4246 which are built to accept up to 8 inputs.

All the holes are pre-punched, with blank plates for any uninstalled inputs. For either chassis, if there are fewer inputs than are supported by the chassis, you can add more inputs, up to the max supported by that chassis.

Both 9 Ghz and 18 Ghz input cards are available. Each card upgrades two inputs. These additions can be done by the owner using only a screwdriver. Contact us with your Radiance Pro model number for pricing. We always sell Radiance products at the lowest allowed prices.

 

Can I add extra output cards to my Radiance Pro?

No. Radiance Pro units all come with fully loaded output card slots. 9 Ghz cards can however be replaced with 18 Ghz cards. Each card contains two outputs. When swapping a 9 Ghz card for 18 Ghz, one output becomes 18 Ghz audio/video while the second output becomes audio only. Contact us with your Radiance Pro model number for pricing.

 

What HDMI cables are recommended?

Below are recommendations direct from Jim Peterson, president of Lumagen, manufacturer of the Radiance:

I am now recommending using only "Certified at 18 GHz" cables (certified by VPL labs or HDMI.org, as opposed to just a manufacturer specification). I recommend passive cables that the manufacturer tests and certifies every single cable manufactured at 18 GHz, rather than certification of the "design at 18 GHz" since cables can vary due to manufacturing tolerances. This insures each and every cable is going to work at the full certified 18 GHz rate. I recommend an active HDMI cable for lengths over 3 meters. I do not recommend installing passives over 3 meter to help minimize the chance of a HDMI cable related call-out.

Here are my current recommendations:

Passive HDMI cables for 2 meters (6.5 feet) to 3 meters (9.8 feet):

Note: Passive cables under 1.8 meters (6 feet) are not recommended.

For long runs from the Radiance Pro output:

What is Radiance automatic calibration?

Automatic calibration allows anyone with little or no training to fully calibrate their display with almost no user input. It adjusts the display's grayscale, gamma, and colours to levels of accuracy that are simply not achievable by manual methods. Just setup a few simple options in ChromaPure software, click "Auto-Calibrate", and then go have a cup of coffee while the process completes, usually in a few minutes. There is no need for the user to understand how calibration works. Suitable for all display types.

 

Why use Radiance automatic calibration?

Previously, calibration required the user to adjust their display manually while ChromaPure software read the results using a meter. The user would loop through displaying test patterns, reading the results, and making adjustments, until the results were as close to accurate as possible. These calibration steps are outlined in our free step by step guide.

Manual calibration has many drawbacks:

  • Requires the user to have access to typically hidden (service menu) controls in the display.
  • Displays often have limited adjustments that do not work correctly, or are cryptic.
  • Displays often have only 1 gamma adjustment, if any at all (compared to up to 21 points with auto-cal).
  • Displays often only have only 2 greyscale adjustments, if any at all (compared to up to 21 points with auto-cal).
  • Manual calibration of colour is typically only done at 6 points (if the adjustments are even available). Automatic calibration is done at up to 4913 points for greatly increased accuracy.
  • Manual calibration is time consuming.
  • Manual calibration requires the user to interpret the meter readings and make the necessary changes in the display. Our free step by step guide is a step in the right direction, but the process is still manually driven and can take hours, especially for someone new to the process.

All of these can result in a less than perfect calibration. Only automatic calibration, done outside of the display, can compensate for these issues.

 

How does Radiance automatic calibration work?

Automatic calibration is an optional add-on to ChromaPure software, and it works in conjunction with a Radiance external video processor. The processor acts as both a test pattern signal generator and calibration device. ChromaPure tells the video processor to display test patterns, measures the results with a meter, and then tells the video processor how to adjust the signal to compensate for display errors. This cycle repeats (often for thousands of test points) until the measured results are as close to perfect as possible. The lookup table of calibration offsets for each point is stored in the video processor.

Once completed, the video processor stays in the signal chain permanently, constantly adjusting the signal in real time against the lookup table to keep the display perfectly calibrated.

 

Why does the number of calibration points matter?

When using a Radiance video processor, calibration of up to 4913 colour points can be done achieving unparalleled colour accuracy. Instead of manually colour calibrating to only the 6 primary/secondary colours that make up the boundary of all known colours (called the gamut), we can now calibrate throughout the entire colour space by measuring and correcting up to 4913 colours. Only calibrating at the boundaries (as is done with manual calibration) can still leave many inaccuracies (see real life example).

This revolutionary level of calibration accuracy has only been made possible by advancements in processing power found in the Radiance family of video processors. Manual calibration at thousands of points is simply not possible because displays do not have look up tables (LUTs) in which to store the correction information. Even if they did, manually calibrating to thousands of points would quite literally take the user weeks to perform.

The maximum number of colour calibration points depends on the model of Radiance you have:

  • 4913 points: Radiance 21xx, 41xx/42xx/44xx/5xxx Pro series
  • 729 points: Radiance 20xx series
  • 125 points: Radiance Mini, XD, XE, XS

Radiance 21xx Features

The Radiance 21xx models were first introduced in 2014. They feature 8x HDMI inputs and 2x HDMI outputs in a 1U and 2U height by 17” wide rack mountable case (with optional rack ears), similar form factor to the (now discontinued) Radiance XS and XD/XE. The 2124/2144 include analog inputs and outputs while the 2123/2143 do not. 4K UltraHD (2160p@60Hz) output resolution is supported by the 2143/2144, while the 2123/2124 support 1080p FullHD output. The 21xx series does not support 4K UltraHD resolution on the inputs. All models features the same video processing quality and include built in Darbee image enhancement technology, allowing you to adjust the amount of enhancement for each input as with all other adjustments. Optional triggers are available on 21xx models and they are programmable. By default Trig1 is on when the unit is on and Trig 2 is on when 2.35 input aspect is selected. If you have RS232 control you can turn the triggers on or off with a RS232 command.

Radiance Pro 4XXX Features

The Radiance Pro 4XXX series features up to 8 HDMI inputs, 4 HDMI processed outputs, and 6 HDMI switched (unprocessed) outputs. All support 2160p60 (4K Ultra HD) and support up to HDMI 2.0 with HDCP 2.2. All are 1U height (some previous models were 2U height) with a 17" wide rack mountable case (with optional or included rack ears depending on model). The 424X-C (compact) model is 11.3" wide and not rack mountable. There are no analog inputs/outputs. The rest of the features are very similar to the 21xx series. Some differences include:

  • The new HDMI 2.0 chips are from Silicon Image and have an internal microprocessor with reprogrammable flash memory. This will allow Lumagen to provide updates when Silicon Image provides a new release and should help to eliminate compatibility issues. Some back story: Before with HDMI 1.X chips each company had to implement much of the HDMI protocols on its own. Often the HDMI specification, or the HDMI chip specifications, left a lot to the imagination. This meant each company had to make independent decisions on how to do their implementation based on incomplete specifications. Now with the internal processor being programmed by the chip manufacturer, and its processor doing virtually all the HDMI compatibility work, issues should be dramatically reduced. Even more so for the Radiance Pro when connected to other products that use the new Silicon Image HDMI 2.0 chips, which many will.

  • The inputs are on "dual input" daughter cards and the outputs are on "dual output" daughter cards. This allows upgrades to be offered when new HDMI technology becomes available. It also allows replacing a single input/output card if there is a surge event that takes out an input/output, rather than the entire unit.

  • The Radiance Pro can have up to eight inputs, and four "processed" outputs. Just as the previous Radiance units have two outputs that can output audio and/or video from the same source, these four outputs also output the same processed video and/or audio stream. Having four outputs allows for a projector, a TV, a Receiver/Audio-processor, and a spare.

  • There can be up to six additional zones of switched (only) outputs on some models (limited to the discontinued 4449). These are independent and give the Radiance Pro up to seven independent zones. This is useful for installers as it avoids the need for a separate matrix switch. An example would be a home with 7 TVs where only 2 will ever be in use at once. Only 2 sets of source devices is therefore required (not 7) which lowers the cost. The Radiance Pro is then used to direct these sources to whichever TVs are in use.

  • The Radiance Pro features much faster switching than previous models as there is no GF9450 deinterlacing chip to have to setup and wait for.

A bit of trivia: The powerful FPGA chip used in the Radiance Pro costs more than all of the parts in the Radiance 2020 combined. This and other aspects of the Radiance Pro architecture mean it sits well above the previously top of the line Radiance 2144 in terms of processing power and flexibility for future upgrades.

Key Features:
  • Up to eight 4k60 HDMI 2.0 inputs (4K60 UltraHD) with 1080p@72Hz and 1080p@120Hz support
  • Up to four 4k60 HDMI 2.0 processed outputs (4K60 UltraHD)
  • Up to six switched (unprocessed) HDMI 2.0 outputs (4K60 UltraHD)
  • Up to seven independent zones (processed outputs are one zone, plus up to six switched zones)
  • Inputs and outputs support HDMI 1.x and HDMI 2.0, with HDCP 1.x or HDCP 2.2, at up to 4k60
  • Outputs are independently programmable for video, audio, or both

Radiance Pro 5348 Features

The Radiance Pro 5348 is the newest version and features 10 x 18 Ghz HDMI inputs, 2 x 18Ghz HDMI outputs, and 1 audio-only output. It uses the same software as the 4XXX models so video processing operations are currently identical. A single 12V trigger is included. Some differences from the 4XXX series include:

Dramatically reduced output jitter and noise

What sets the Radiance Pro 5348 apart is the electrical improvements in the design. While using the same HDMI chips, and FPGA, the use of linear regulators for 28 critical power supplies, and the addition of an HDMI dejitter output buffer, has dramatically reduced output jitter and noise. The use of Faraday cages for all nine DC-to-DC switching-regulators dramatically reduces EMI. As an example, the current 18 GHz Rev 1.4 output card in a 4446 has a HDMI data jitter of about 80 pS (HDMI specification requires 102 pS or less for 18 GHz). In comparison the measured HDMI output data jitter on the Radiance Pro 5348 is 45 pS, or just about half. More importantly for audio, the HDMI output clock jitter has been measured at about 10 pS. This is a nearly ideal clock to send to the audio processor.

People have asked if reduced jitter and electrical noise matters. Yes, it does. Based on A-to-B testing with the Lumagen Demo Theater’s Trinnov Altitude 16, the Radiance Pro 5348 does make a significant improvement for appropriate content (e.g. Greatest Showman “Never Enough”). Some have asked about the current 4XXX product line: “The Radiance Pro does not process audio. So how come audio sounds better when it is running through the Radiance Pro?” The difference is lower jitter and reduced electrical noise. The Radiance Pro 4XXX output jitter and electrical noise are already dramatically better than other products we know about, but the 5348 takes jitter and noise reduction to what we consider is the ultimate audiophile level.

Some have said that a high-end audio processor’s dejitter circuit can handle higher jitter levels. In Lumagen's experience, audio processor dejitter circuits can improve the jitter as the signal works toward the DAC’s, but there is a limit to the improvement. The advantage the Radiance Pro has compared to traditional dejitter circuits is it completely regenerates the HDMI audio output using a very low jitter crystal clock chip for the HDMI audio clock, and then passes the HDMI signal through two stages of PLL dejitter circuits. Using linear power supplies also helps keep the jitter low by isolating the noise from the digital circuits away from the HDMI integrated circuits.

Lumagen is also being asked if the lower jitter of the 5348 will improve video. Since the 4XXX series already has output jitter well below specification, the 5348 going from 80 pS down to 45 pS for the data is not likely going to improve the Bit-Error-Rate (BER) on the HDMI connection. The data reaching the projector/TV should be identical and so there should not be any visible difference.

But, what about the reduced electrical noise on the Radiance Pro 5348 output? This gets into the question of can electrical noise injected into a projector through the HDMI cable affect the image’s background “analog” noise. For a digital display technology such as DLP, the answer in Lumagen's opinion is no. For a projector with an underlying analog display chip technology (LCOS, DiLA) the answer is that there is a chance it might make a visible improvement. Each system needs to be evaluated individually to determine if there is any visible change. As with any image quality analysis, the final assessment must be done at viewing distance (typically 1X screen width for 4k). If you cannot see a noise reduction at viewing distance, any improvement is moot.

Lumagen has customers who say they can see a visible improvement due to lower noise using an external linear power supply and they believe they saw a slight image improvement (lower background noise) using the 5348 versus the 4446 in the Lumagen Demo Theater RS4500 with the supplied Radiance Pro external digital power supply. These difference are small, and unlike the audio where Lumagen is convinced they could tell the difference in a blind test, for video the difference would be difficult to tell which technology is in play in a blind test (in their opinion). So, thye are not claiming you will see a visible improvement on an analog projector chip such as used by Sony and JVC. However, they believe they did see an improvement, and you can test this for yourself, assuming you have both a 4XXX and a 5348. They admit this may be hard to accomplish for most people.

The Radiance Pro 5348 uses a HDMI PLL re-clocking chip on each of the three outputs. Lumagen believes this HDMI buffer integrated circuit has slightly slower output edge rates that will be more forgiving when used with projectors with marginal HDMI input designs. These chips reduce jitter, and edge rate, but they also give the 5348 control of the output signal for level and EQ. Note that the default for the 5348 is to not have output EQ. The 4XXX series always have output EQ.

In the Lumagen demo theater all supported combinations of 5348 level and EQ work well. Not having EQ is intended to assist active fiber cables which do not have the appropriate amount of attenuation in their input buffers to account for the fact that normal HDMI outputs have cable EQ. This EQ typically in HDMI outputs, and the output edge rate, must be attenuated by a cable, or a well-designed input buffer in the case of the active fiber cable. With the default “no EQ” setting a passive cable should be in the 2-meter to 3-meter length range. For a projector with a marginal HDMI input design Lumagen believes this programmability may help the projector lock on to an 18 GHz HDMI video signal.

Upgradeability to LAN interface

The Radiance Pro 5348-USB has the same RS232 plus USB (USB to RS232 internally) connections as the Radiance Pro 4XXX models. One of the 5348 design changes is that the 5348 can support a Lantronix XPort Ethernet-to-RS232 interface on the small 5348 microprocessor daughter card. If you buy the 5348-USB and tell us in your order you want the option to upgrade to the LAN interface, we will use a different case bottom sized for the LAN port connection. You could later purchase the LAN version of the microprocessor board, and then swap out the microprocessor board in the field for one with the XPort option. This is a straight-forward task and almost identical to swapping an I/O card in the 4XXX units. Note that the XPort LAN connection would replace the USB port. If you do not order the 5348-USB with the LAN case, you can still upgrade but the unit has to be sent in for the change.

Reviews/Testimonials

"So far I have tested [my] 2041 with the actual set-up of my [old] XS and I was very impressed. The 2041 gives a tad clearer picture than the old XS, even if Darbee Vision is disabled. At low levels DarbeeVision really improves the picture quality without adding annoying artifacts." - Stephan G.

"Just to say thanks for convincing me to buy the Radiance Mini! Calibrating my TV is now so much easier and the 125 point calibration fixed the problems I had with oversaturated Red and Green, it's subtle but my image is now more natural and my greyscale is now perfect. This device has also a lot of side features that are really nice like the gamma factor and the fact that the radiance has many memories is really great for day/night viewing settings. That really brought my TV to another level." - Stephane S.

"It's obvious that I love the Radiance XS. There isn't a component that I used it with that wasn't improved by using it, nor a feature that I found it to be missing. There is so much inside of the Radiance products that any review that doesn't go for 10,000 words isn't going to be able to cover it all. Lumagen has packed their Radiance line with more features than anything else I've used and really brings something to any system you use it with. Since I finished testing the Radiance just a couple weeks ago, Lumagen has improved it to allow you to convert to any of the 3D formats for output, made it easier to use Reference or Adjustable patterns, and they have plans to add even more feature going forward. In addition to offering these free updates at their website, they also run their own support forum as well as actively monitoring the forums at AVS to support their users. You can even call and actually talk to their employees to get support for your issues. Their website also has an archive of Tech Tips to help you setup certain features that might be fairly complex to do. With a device as capable but complex as the Radiance, this level of support is important and sometimes essential. Unless a display is absolutely perfect in all aspects, and each component is as well, any theater can benefit from the Radiance. You may not use all the features, but it has the power and ability to grow as you change your system around. There have been very few products that I can enthusiastically recommend as highly as I can the Lumagen Radiance. It really is a component you need to try and see for yourself to understand the difference it can make." - Chris Heinonen of HomeTheaterHiFi.com (read full review)

"I'm not a scaler/processor type of person, and really saw no real need for one since you can get HD directly from a Blu Ray player. Of the ones I've seen in action in the past, the only one I've been impressed with was the VP-50, but never to the point of wanting one for myself. And based on the cost of these units, the reason for having one could never be justified enough for me to ever consider one.  However, today was a real eye opening when Craig connected his Lumagen Radiance up to my Electrohome Marquee 9500LC CRT projector. At first we had it hooked up 1080p/60Hz. Then Craig noticed that it would be best at 24Hz into the Radiance. After switching my Sony BDP-360 Blu Ray to 1080p/24Hz and running the output of the Radiance at 1080p/72Hz everything I had ever thought about a video processor changed. My 9500LC interpolated the 1080p/72Hz and without any adjustments to the projector. The image I saw on the screen stunned me. It was tight, bright and very sharp. Even sharper than anything I've been able to get using 1080p/60Hz. I asked Craig to find out what one would cost... 1080p/72Hz is now a must have for me. Since the Radiance does it so well, owning one is now tops on my list. Finally - a processor that does not muck up the signal!" - Mike Parker (Projector/Home Theater guru)

"The Radiance XD is the Swiss Army Knife of video processors. ...In my experience, there is nothing out there that converts SD to HD as well as the Radiance XD. Lumagen's proprietary up-conversion is excellent. As good as the best Gennum VXP and Silicon Optix HQV processors are, the Radiance XD has a clear (pun intended) advantage in the quality of up-conversion. ...The Radiance XD is an amazing product. It will elevate the performance of any video display beyond what is possible with the display's internal controls. The results are amazing for video displays in any and every price range." - Doug Blackburn, Widescreen Review, Issue 139, March/April 2009

"The Lumagen RadianceXD is the single most useful piece of A/V equipment I work with. I use it for my own setup, and frequently recommend it to clients. It can correct for virtually all errors in both display and source, and make a inexpensive set behave like a professional display. Lumagen support is unsurpassed. Bugs are promptly addressed, and set-up questions quickly answered." - Carl, New York City, ISF Calibrator

"Anyone who owns the Radiance will tell you how amazing it is. It does everything you've heard it does, and then some. It is the most important and most powerful piece of equipment in my setup. But even more incredible is the way Lumagen stands behind its product by listening to us owners, with a constant influx of updates and bug fixes. No issue stays unresolved, and new features are added all the time, long into the lifecycle of the product." - Dave (Madison, WI)
