Hi guys,
I have asked for help a couple weeks ago and I didn't recieve any responses Sad

. So, I tried to give it another try myself and this time with I1 display 2 and CHCFR software on my Samsung LN40A650. The graphs can be found at this link

If i adjust the brigtness based on the fact that "The Y value at 10 IRE should be equal to 0.65% of Y value at 100IRE", I need to adjust the brightness slider to around 60 or so on my sammy. On the other hand, if used the pluge pattern, I will hae to adjust the brightness slider to only around 45 or so. The question is how reliable is I1 display 2 at 10 IRE?

Also, the TV comes with a gamma setting which can be varied from -3 to +3 in increments of 1. The gamma graph is not close to 2.2. I had set the gamma to be +2 on my TV ? How do I adjust gamma?

I hope I can recieve from input from you guys this time.

Thanks,
Dagarshali

I am not familiar with your TV, but the Probe is pretty accurate and the 65% method worked better for me but i got the same results looking at pluge too(CRT Front Projector)
Try doing a set up with the gamma setting to 0 then move up a notch and measure again, see what changes were made. The best way to learn is from experimentation and watching and documenting results. Keep note on what you do and what the changes are.
