Sounds like the background light to me. TFTs have one disadvantage: the brightness varies depending on the angle at which you look at it. I assume the more money you spend the less a problem it is. By tendency, I have an effect like this, too, but it is so minor that I only realise it in very dark, black pictures - then I have a very low, hazy grey shine at the upper and lower frame of the monitor, 2-4 mm wide. but again: very minor, it does not irritate me, and invisible in everything but very dark pictures. But after all I only spend 180 Euros for a regular priced 250 Euros-monitor. I could as well spend 400-500 Euros on a monitor of the same size.
