I've just bought a new LCD TV.
About 1 year ago I calibrated my old LCD using some sample AVI videos, e.g. something like levels.AVI where I could check where I should set levels on my PC to 16-235 or 0-255. The video displayed black-gray-white bars where I could see if I get the whole luminance range.
I'm quite sure I found the link to this videos on the AVS forums. I have been searching for an hour now and cannot find them anymore.
I hope someone can help out.
