Anyone have the above combination and calibrated with Colorfacts?


After Toms comments about his DVI D1 calibration with Colorfacts, I'm curious to what settings need changing with a Radeon 9600 via DVI, and if the results are noticably better.


Anyone? :)

Gary,

Radeon 9700, DVI, Catalyst 3.0, TheaterTek 1.5 (default), Stewart StudioTek 96" 1.3, these are the values I found:


NEC HT1000

Reference setting = Movie

Gamma correction = Natural

Red = -16

Green = 6

Blue = 10

Yellow = 2

Magenta = -16

Cyan = 5

Color gain = 0

Color temperature = 6500°K


And here come some graphs:

Not bad, uh? ;)


Please refer to www.htprojectors.com , free section of the shoot out, to see testing environment & conditions.

Nice work, Andrea,


I like that you post the spectral scans at different IRE levels. I had never thought to do that until I saw you doing it. It's one thing to have the same x,y coordinates across the gray scale, but that can be done with metamers (colors that appear the same, but are created with different spectral output).


Seeing your actual scans shows just how linearly this machine tracks at those levels (especially with them all scaling to the same height like that). What bulb does this use that produces that Cyan peak in addition to the other three?

Wow - what did Mark just say?:confused:


LOL, thanks for the replies - I use PowerDVD, not TT, so the settings will differ, but I'll try them anyway. It's easy to put them back.


Great graphs - easy to see what's going on and understand.


I'll let you know what I find.


Many thanks,


Gary.

Thanks, Mark, and I'll go further!

As I posted elsewhere, I'm starting to understand WHY 3 projectors with similar RGB values can sport different colors:

SIM2 HT300 Plus

NEC HT1000

Marantz VP-12S2



It's obviously a matter of taste, but there's no question that the S2's red is more "calm" than the 300 (that I personally like the most).

But, without looking at the spectral graph. I would never had the chance to understand this behavior! :p


And I'll emphasize this on next graphs, since I guess we DO take into account the spectral response at different light levels...


Regarding the NEC cyan "friendliness", I must say this is typical to EVERY DLP I've examined, but doesn't apply to D-ILA, nor LCD or CRT. It's s common characteristic that seems related to the color wheel, I guess: the only thing that appears really DIFFERENT from other technologies. Only my guess, anyway! :p


Gary: thanks!
