Back when SGI was producing workstations with Trinitron monitors we had complaints from PC users (probably running Windows for Workgroups) that colors in images we produced were bad. In fact, every PC was different.
I'm not surprised. PCs had wierd pictures because their monitors were different from everything else that had gone before it, likewise with Macs. They have a different gamma than TV monitors, so people editing video on a computer had a different-looking picture than the end-user. And you had the same issue with printed media (ink or photo).
I'd forever be seeing video with the black level pushed up to about 30%, as they'd maladjusted a normal signal to suit their monitor, instead of calibrating their monitor, and adjusting their video using a scope. To be fair, we'd see the same thing with non-computer edited material, for the same reasons. Edited on uncalibrated monitors, and the editor had no real idea about what they should be doing.
Real video (TV/DVD) on the LCD computer monitors looks awful, for same reasons (gamma, pale phosphor, mal-adjustment, a different video 0 to 100% range than PCs used, different resolutions with awful scaling, and a different frame rate). Trying to do the wrong with with the wrong monitor just looks bad, and using it as your reference messes it up further for everything else.
