 | | color, contrast and brightness problems - any idea?

|
Hi all, I have a problem and no idea hox to fix it. I'm working on a notebook with active tft-display. Rendered pictures seem to be brilliant with enough brightness and contrast. Whenever I see one of these pictures on a PC with CRT I'm shocked. (...) (21 years ago, 11-May-04, to lugnet.cad.ray, FTX)

(...) One thing you can do is try to make your notebook match the CRT. Turn down the brightness and/or contrast some. I don't know if you have this option on your notebook, but all freestanding monitors have some controls built in to them which (...) (21 years ago, 12-May-04, to lugnet.cad.ray)

(...) Basically, the problem you're seeing is that Windows does no gamma correction, and your two machines have different monitor gammas. (see (URL) for an explanation) To fix this, in theory, you basically have to calculate your current monitor's (...) (21 years ago, 12-May-04, to lugnet.cad.ray, FTX)

So why does my monitor come in at about 1.7 on the first chart, and 2.4 on the second? I'll accept that the second makes it far easier to find the best match, but I won't accept that my estimate is off by 0.7 on the first chart. There's absolutely (...)

(...) Hi, I agree with you that the viewangle has a big influence on the picture if you use a TFT. As a result of this I think it doesn't matter how I finetune my TFT or grafic card settings. I have no real chance to fix the viewangle... hmm maybe (...) (21 years ago, 13-May-04, to lugnet.cad.ray, FTX)

(...) Well, I found both of those charts off of google, so i don't know which one is more accurate. At the risk of confusing things even more, I found another page with a similar test: (URL). I believe this one is accurate, since he give the formula (...) (21 years ago, 14-May-04, to lugnet.cad.ray, FTX)
