Did a greyscale calibration a week ago by following the tutorial in http://www.curtpalme.com/forum/viewtopic.php?t=10457, I'm using eye one meter, 96" 1.3 gain grey screen and tried on User 1 mode.
Strange thing is: when adjusting red and blue RGBHighEnd (gain) for 80 IRE, red is way too high for initial setting (~300%), I tried to drop red gain all the way to 0, it was still way above 120%, This affected the final results quite a bit for 80-100 IRE (Delta E > 10). Although the tutorial does not advise to adjust green, I gave it a try, i had to tune up green gain from 50 to more than 80 to get all 3 colors in ~100% range, but somehow I feel the screen is greenish..... Need some advice here which part I did wrong? For User 1, which color mode should I use, warm, normal or other mode? Many thanks!
The detail step described in the tutorial:
STEP 6.3: Adjust the red and blue RGBHighEnd controls on your display until all three RGB Level bars are at 100% or very close. You'll have to play around the first time to figure out which way to adjust the controls to add or remove red and blue as all displays work differently. Once all three are close to 100% you should be close to the D65 point (x=0.313 and y=0.329).
Note that we only adjust red and blue. Green is typically the reference and should be left alone as adjusting the green RGBHighEnd control (and balancing the red and blue levels to match) has the same effect as simply adjusting the overall contrast.
Ok! So now the 80 IRE point is set correctly to D65! Don't get too excited, you're going to adjust it again very soon ...
If greyscale was accurate, how could you get greenish picture?
