|
|
I ve read on the Calibration for Dummies thread that contrast should be set to 30-40 ftL if you have an lcd. After googling I ve read some other people saying that up to 80 ftL is ok for lcds. The reason why I am asking is that my living room, where my tv is, I have no windows. So setting my tv at 30-40 ftL will make it look really dull during the day.
Also, I was wondering if I could set the gamma higher than 2.2. I have finished calibrated (with 80 ftL contrast) and all the values are really excellent(all colors close to 100%, DeltaE Values less than 3, luminance follows the line, Gamma 2.2) , but to my eyes it looks like theres something missing. it looks to me a bit washed out to my liking. Before I calibrated it the blacks looked really black. Is it ok for lcds to go higher in gamma, lets say up to 2.5?
Will the combination of too high contrast and too high gamma be bad, if all the other values are properly calibrated?

I ve already tried calibrating with 40 tfL. The picture wasnt bright enough to watch during the day. I even tried 70 tfL and it still wasnt enough.
Funny thing is that before the calibration the tv was at 130 tfL and the black levels were really good.
I just want to know what the limits are that I can push the gamma and the contrast before the calibration is not optimal.
Also, is it still correct to use the 0.65%x 100 IRE Value to find the correct brightness if your contrast is at 80 tfL?
And what the correct percentage would be if your target was gamma of 2.5?

I always find myself reducing Gain/Contrast below the manufactures recommended settings to get a better contrast ratio and Gamma.
