Confused about meters? See our FAQ: Which meter is right for me?

If you have been interested in calibrating your own displays but have been deterred by the high cost of color meters and good software, this bundle is for you! Finally, professional quality results at a non-pro price!

X-Rite’s new EyeOne Display 3 colorimeter (officially called the i1 Display Pro III) is truly groundbreaking! It performs three times faster and read lower light levels better than the Chroma 5, all at a lower cost!

It's not simply a successor to the Display 2, the Display 3 is based on a completely different design and offers a price/performance profoundly superior to the Display 2. In fact it's profoundly superior to any colorimeter at anywhere near the MSRP price of $299.

It is also one of the easiest devices to use because it requires no dark reading calibration. By comparison, the Display 2 requires a dark reading when the meter is initially connected. The EyeOne Pro and Hubble also require an initial dark reading plus periodic dark readings throughout the calibration session.

The Display 3 PRO takes the regular Display 3 one step further and offers professional grade accuracy at a price affordable to the amateur hobbyist or enthusiast. Our tests show that the Display 3 PRO offers accuracy for color and the white point that in the majority of cases exceeds that of the EyeOne Pro spectroradiometer. Furthermore, its luminance readings are far superior to the EyeOne Pro, both in terms of general accuracy and certainly in dynamic range. (Complete details below)

Quite simply, we believe that this meter is the best sub-$1000 meter for video calibration on the market today. Is it a true reference device? No. But at this price it comes as close as any device we are aware of to this standard.

Features

  • Excellent low-light performance (real-world performance shows good results down to approximately 0.003 cd/m2)
  • No dark reading
  • Built-in tripod mount
  • Built-in hinged high-quality diffuser
  • Very good accuracy
  • Extremely fast
  • Available in PRO configuration, which enhances accuracy even more
Design

The Display 3 is an enclosed, non-contact device similar to much larger and more expensive colorimeters, such as X-Rite’s own Hubble or the Klein K-10. Light enters the unit through a lens and is focused onto filtered photo-sensitive diodes. The diodes transmit discreet electrical signals representing red, green, and blue. The advantage of this design over contact meters (such as the Display 2 or Chroma 5) are many:

  • The lens is able to capture and focus more light onto the filtered diodes, which provides much better low-light sensitivity and much faster readings.
  • Because the filters are completely enclosed, they are less likely to deteriorate as a result of exposure to environmental factors.
  • The non-contact design is conducive to measuring front projectors, remains isolated from the heat of plasmas, and doesn't risk damage to LCD screens.
  • The Display 3 also includes a built-in hinged diffuser that swings in and out of place easily for measuring illuminance directly from a front projector’s lens. Unlike previous products, this diffuser is color neutral allowing for accurate readings in illuminance mode. Off screen readings are still the preferred method for measuring front projectors, but at least one can now measure from the lens without having to color correct the results.
The only drawbacks to this non-contact design are that it requires the extra expense of a tripod and it is more sensitive to contamination from ambient light. To address this, X-Rite designed the meter so that it can be used in contact mode as well. It has a counterweight firmly attached to the USB cable.

Performance

After testing for some time we've been nothing short of amazed at the level of performance it provides at its price point. Despite the fact that this colorimeter is a successor to the Display 2, it so vastly outperforms the Display 2 that a better comparison is probably the Chroma 5.

Speed: See Video (1:17)

The Display 3 is extremely fast. In fact below 10 cd/m2 we actually slow the unit down to improve repeatability. Above 10 cd/m2 its speed is comparable to the Klein K-10 and X-Rite Hubble, each of which costs several thousand dollars.

To test the Display 3’s speed, we used it for a complete auto-calibration run in ChromaPure. The process took 7.5 minutes to complete. The Chroma 5 clocks in at 23.5 minutes! This indicates that the Display 3 is about three times faster than the Chroma 5. To confirm this, both were run through a full grayscale run. See the video above which confirms the auto-calibration findings.

Low-light Sensitivity: See Video (2:18)

Another area in which the Display 3 excels is low-light sensitivity. The Chroma 5 is rated down to 0.01 cd/m2 and this seems about right. However, the Display 3 will read light that is one-third as bright. To test this we used the AccuPel DVG-5000 video test pattern generator to feed increasing lower intensity signals to a Pioneer Kuro, the champ of low black-level displays.

The results of this test confirm that the Display 3 reads down to 0.003 cd/m2, or 0.001 fL.

Consistency: See Video (1:23)

One of the most important aspects of a colorimeter's performance is its ability to return stable and consistent readings, especially at low light levels. We worked very hard to implement support for the Display 3 in such a way that ensures this. Here’s the Display 3 reading a 30%, 20%, and finally a 10% stimulus test pattern off of the screen from a front projector. As you can see in the video above, the consistency of the Display 3’s readings, even at very low light levels, is exemplary.

Color Accuracy

This performance parameter can only be finally determined after sampling a large number units. Often, the biggest variable in a meter's color accuracy is the unit-to-unit variation resulting from mass manufacturing with affordable materials. We can say that the production units tested are excellent in this regard. The Display 3 shows errors no higher than xy0.006 for both color and white relative to a $10,000 reference spectroradiometer. This is performance comparable to a stock Chroma 5.

It will take time before we can determine for certain the extent to which this level of performance can be maintained and, more importantly, how well the accuracy holds up over time. We believe that because the filters are in a sealed container that the Display 3 will age much more gracefully than either the Display 2 or Chroma 5. However, as with any filter-based device it will always benefit from calibration against a reference spectroradiometer.

Summary

The X-Rite Display 3 is a truly revolutionary product. It offers near professional performance at a price affordable to any enthusiast. In fact, its performance is so close to professional colorimeters, such as the Klein K-10 or X-Rite’s own Hubble, than it has become extremely difficult to justify purchasing such devices that come in at 10-20 times the cost of the Display 3. The Display 3 is not perfect. At low light levels, its otherwise blazing speed slows down considerably. Also, we would really have liked to see some type of aiming device, similar to the laser on the Hubble. However, this would have no doubt increased the cost of the unit.

The color analyzer is often the weakest link in measuring and adjusting a display device. Because of the unprecedented price/performance ratio of the Display 3, we would argue that it is among the most important products ever developed for display calibration.

What is the EyeOne Display 3 PRO?

While groundbreaking, the Display 3 is still a relatively low cost mass-market device whose tolerances are looser than what you would find with more expensive professional color analyzers.

Our ChromaPure partner has developed a version of the Display 3 which we've named the Display 3 PRO, that offers substantially enhanced accuracy across multiple display types including:

  • Generic LCD
  • Samsung Standard backlit LCD
  • Samsung LED backlit LCD
  • Sony Standard backlit LCD
  • Sony LED backlit LCD
  • CRT
  • Plasma
  • Front Projection-Screen
  • Front Projection-Lens
What they have done is provide a software-based refinement to and expansion of the existing calibration tables in the individualized license file delivered with each unit.

To understand how this works, it is important to first understand the source of errors in tristimulus colorimeters.

In an attempt to accurately model human color vision, in 1931 the CIE defined the standard observer, which is characterized by three color matching functions, shown below.



A filter-based colorimeter attempts to mimic human color perception by matching these curves. However, accurately matching these complex curves using any reasonably affordable filters requires correction with a reference spectroradiometer. Otherwise, you cannot achieve the desired accuracy with different display types. A spectroradiometer does not rely on filters as a way of mimicking human color vision, but rather measures the spectra of a display directly. Its accuracy depends only on the bandwidth, sensitivity, and resolution of the device.

The inaccuracies of a filter-based colorimeter arise from a variety of sources:

  • The standard modes that the factory Display 3 ships with are based on a generic correction from a reference device. The same correction is applied to all Display 3's.
  • There may be some unit-to-unit variation. This was certainly true of the Display 2. Only extended experience will reveal the degree of unit-to-unit stability that the stock Display 3 offers.
  • The instrument's accuracy may decline as it ages. However, because it is essentially a non-contact design whose newer generation filters are installed in a sealed environment, it will likely age more gracefully than previous models, such as the Display 2 and Chroma 5.
  • There is a natural variation in consumer displays—even displays of the same type!—so the operating modes of the colorimeter are no more accurate that these variations allow. The calibration tables of the factory Display 3 can only be derived from the general performance characteristics of the display type, not the specific display being calibrated.

Taken together, these four sources of inaccuracy—generic factory calibration, unit-to-unit variation, degradation from aging, and a lack of consistency among displays—result in a device that, on average according to our tests, typically deviates from a reference spectroradiometer in the range of 2-9 dE (CIELAB), depending on the display type and age of the probe. Our PRO version of the meter will cut this source of error in half.

Of course, the best way to minimize these errors is to use your own reference spectroradiometer to correct the Display 3 for each calibration session on a single display. ChromaPure provides an Meter Correction module for just this purpose. However, the vast majority of consumers cannot afford a true reference device, which are very expensive. SMPTE requires a reference instrument to have a minimum accuracy of ±0.002 for the measurement of xy chromaticity coordinates at any luminance above 3 fL. The only instrument capable of this level of precision is a 5nm spectroradiometer. A tristimulus colorimeter will not offer this level of accuracy, nor will an 8nm or 10nm spectroradiometer.

The Display 3 PRO virtually eliminates 3 of the 4 sources of error and lessens the fourth for a small fraction of the cost of a true reference device.

  • First, we individually test each meter against a reference spectroradiometer on a CRT, several LCD flat panels, a plasma flat panel, and front projector with a standard UHP lamp in both luminance and illuminance modes.
  • Second, we include correction figures in the individualized license file that align the standard Display 3's response to our reference device. These two steps alone greatly improve the built-in calibration tables for the Display 3 and completely eliminate any unit-to-unit variation.
  • Third, for a modest fee, we will periodically re-calibrate your Display 3 PRO to ensure it retains its initial accuracy. This service eliminates the problems associated with exposure to the elements over time.
The Display 3's accuracy is reasonably consistent when reading CRTs, plasmas, and front projector screens. The biggest problem by far lies with LCDs. Using the Standard mode the Display 3 may read one LCD very accurately and yet be considerably off on another. There simply is no consistency when reading LCDs. Contrary to one widely-repeated myth, this is not an issue directly related to the difference between CCFL backlit and LED backlit displays. Some LED displays actually give the Display 3 less trouble than their CCFL counterparts. Also, the Display 3 can maintain considerably different levels of accuracy when comparing two CCFL displays. The problem isn't with LED backlighting. The problem is LCDs period. To address this problem, the Display 3 PRO ships with 5 different LCD modes. We may add additional LCD modes as needed.

Is the EyeOne Display 3 meter modified in any way?

No. The meters sold by us are NOT password protected or altered in any way, so they may be used with other software products.

Some vendors password-protect or alter meters such that their software will only work with meter(s) sold by them as well as not allowing their meter(s) to work with other software.

As a policy we do not password-protect or alter the meters we sell in any way. Once you purchase a meter from us, it is yours to do with as you wish.

Can my Display 3 be recalibrated?

Yes. For the same modest fee, your Display 3 can (and should) be periodically recalibrated to the same PRO level to ensure it retains its initial accuracy. This service eliminates the problems associated with exposure to the elements over time. We recommend doing this yearly. See our BUY NOW buttons above. You pay for shipping to us and for US customers we pay for shipping back to you. (International customers pay shipping in both directions)

The service includes a certificate of calibration that itemizes all the corrections that were applied to the meter.

Recalibration is the same as upgrade to PRO. The same steps are performed.

Can I calibrate front projectors?

Yes. For best accuracy, we recommend calibrating front projectors by taking readings directly off the screen. However, for those who wish to take readings directly from a projector's lens, the Display 3 offers a built-in color neutral diffuser.

What's included

The Display 3 ships together with ChromaPure software. The Display 3 has a built-in tripod mount (for use with any camera tripod) and hinged high-quality diffuser.

So is there any difference in the hardware itself between a regular and a pro model?? From the description it sounds like it's the software only that's different - "calibration tables", and it's not clear if those are built into the unit or in the chromapure software. Either way, the words "Recalibration is the same as upgrade to PRO. The same steps are performed." seems to confirm that the upgrade to the Pro is basically just a calibration against a reference spectroradiometer. Can anyone confirm this?

No, no difference.

It is built into the license file.

Yes, it is calibration against a reference spectroradiometer.

It's a little disappointing that they don't all come that way when new, but I understand, given that there's extra labor involved...

In any case, which would you recommend; recalibrate a chroma 5 (if it's even possible, given that it's tied to an old-ish version of calman) or get this one?

Hello Tom and Kal.

First sorry for my english i use translator

I have some questions on the display 3 pro.

Since I do not have tripod, and it will use patterns APL

The display 3 was working well as colorimeter of contact?


It affects the temperature of the screen (principally in plasma) as 2 or LT, or this affects the model less like to her chroma5.

All the time must be on the screen to obtain precise measurements on a plasma.

In case of her buying,all that the time to come to Spain (the model pro)

Thanks and regards

It works well in the contact mode.

The filters are sealed and not sensitive to changes in temperature.

Very, very fast.

Shipping to Spain takes 2-3 days. Then it usually takes another 3-4 days to get through customs.

NOVEMBER 1, 2011: New lower price on Display 3 meter packages



Effective immediately, we've just dropped the prices on our Display 3 / ChromaPure meter packages.

The new groundbreaking Display 3 meter performs three times faster and is able to read lower light levels than our previously recommended general purpose meter, the Chroma 5. Better features, better performance, and at a substantially lower cost - now even lower still!

The new X-Rite Display 3 offers near professional performance at a price affordable to any enthusiast and home user. In fact, its performance is so close to professional colorimeters, such as the Klein K-10 or X-Rite’s own Hubble, than it has become extremely difficult to justify purchasing such devices that come in at 10-20 times the cost.

For complete details on the performance of the new Display 3 including videos, see our Display 3 order page here: http://www.curtpalme.com/ChromaPure_EyeOneDisplay3.shtm

Display 3 PRO Calibration SALE



Looking at getting a new TV or projector this holiday season? Make sure to calibrate it for the best results. To aid in this endeavour, Display 3 PRO calibration packages are now on sale. Only until January 15, 2013.

When it comes to home theater calibration, the color analyzer is often the weakest link in measuring and adjusting a display device. Because of the unprecedented price/performance ratio of the Display 3, it is most certainly one of the most important products ever developed for display calibration in the last 10 years.

The Display 3 PRO takes the standard Display 3 meter one step further and offers substantially enhanced accuracy across 10+ display types with colour and white point accuracy that in most cases exceeds that of the EyeOne Pro spectroradiometer.

When someone needs to choose one single sub-$1000 meter for video calibration, the Display 3 PRO is the number one choice as it offers professional grade performance at a price affordable to the amateur hobbyist or enthusiast. No other single meter even comes close.

It is a phenomenally fast reading meter, perfect for performing completely automated calibration using ChromaPure Auto-Calibrate with a Lumagen Radiance video processor in record time. ChromaPure Auto-Calibrate allows anyone with little or no training to calibrate their display to professional standards. Just select a few options, click Auto-Calibrate, and then just go have a cup of coffee while the process completes. Curious? Watch the Auto-Calibrate demo video to see how easy and fast it is.

For complete details on the Display 3 PRO meter see our Display 3 PRO order page:
