This is what you need for a 4m screen Very Happy

Not 100% correct.

For a blend you need 2 ! Wink

The tv One Units are not HDCP compliant, right?

They say they are but I have had issues. the pic come and then turns to snow. So i use the MUX-HD which works perfectly and doubles as the HDMI splitter and has 4 inputs which is perfect for me. I just have the sat box and two Blu ray players. My Oppo and the LG BH200 combo unit.

I keep telling them its not working right and they keep trying to fix it with each firmware update. At least now I can see it trying to sink and lock on. before it was just a black screen.

Athanasios,

why are you using two Lumagen XS for video output ? Is there a reason ?

The Radiance has two video output ports.

Yes there is. both PJ need perfect color calibration and gamma. without the two radiance's its very difficult . you need to have a perfect gamma for all % white. In a perfect world a 256 point gamma adjustment would be great!! Also you need to make sure the luminance of RGB are equal and also the Hue of CMY. all this is key. many many hours of messing around made me realize this.
Both PJ's need to match as closely as possible otherwise the blend zone will be visible where the gamma is off since the blend scalers can only choose a single gamma point in the blend zone. If they were able to choose say an 11 or 21 point gamma for each % white
then it be much easier, but then again you still might not have both PJ showing the same gamma point at each % white pattern.

I hate to say it, but when all is said and done, a good digital is going to take about 1% of the time and might not be that much more expensive overall. And the new ones have pretty damn good black levels and color anyway.

If I had the dinero (which you must if you're considering the hardware required to do the blend), I'd probably only do a blend in these circumstances for the fun and technical challenge. If you want to actually watch movies, digital is going to have vastly better sharpness and ANSI, only slightly worse blacks, and take three hours from cutting the tape to watching a movie - including running the cable and mounting it, instead of 300 for the blend.

Nash, how many movies have you watched on yours, how long have you been working on it, and how close is it to optimal? I'm not ragging on you here; it's obvious you've loved every minute of it and that's a great reason to do it, but it's important for someone to know if they're considering doing it themselves...

I agree peri, but where is the fun? I know some dont understand but I love the challenge of doing things most would not want to attempt.

Just yesterday i went to my local high end audio shop and they have an LED Runco set up. Sure it was sharp as hell but I still like CRT better.
there is just something about it. If i did not enjoy dealing with the complications of a Blend and CRT in General i would have stuck with Digital.

As I said many times it's personal preference. And at this moment in time I prefer a CRT Blend.

And I have have many E-mails for people wanting to blend , I always tell them its not for the faint of heart.
It take lots of patience , time and know how. Unless you have a pro calibrator like Ken Whitcombe to set it up
i discourage them and tell them to stack.

I have watched the past few weeks about 4 movies a week. before that maybe 2 movies in the past 5 months.
With each calibration session I am learning more about blending and more about calibrating having fun and frustration along the way.

Watch I'll get the blend all done and looking perfect and I'll switch Wink

I have spent some hours in the past weeks to see some digitals:

Runco Full HD DLP (1-chip), Sony SXRD Full HD, JVC D-ILA Full-HD.

It does not take long after watching some material to see that CRT is still the KING for me.

Some scenes just do not have the "film look" i wanna have when watching.

on a single marquee with the peaking circuit this is also true, the difference is huge, the increase in shadow detail with lower gamma setting is something to be experienced.
i have a testpattern 1920*1080 with all 1on 1off vert and horizontal squares and i wonder which dig pj fully resolves that.
tested on a plasma tv (fullhd lol) and it didnt pass the test not by a long shot.

I think 1064X800@72Hz on the Barco 909 will be tack sharp. Haven't tried it till now.

Will easily compete with a digital.

I need to go, but I remember measuring MTF with Scott and I think it wasn't till we got to 800x600 that MTF shot up. I don't think it ever gets anywhere near digital though.
