I know I already posted regarding an issue with my 21" base screen having a tint issue. (Pure white at top quarter of screen running into off white/yellowish at bottom 3/4). But yesterday my advanced replacement arrived. It is significantly better. Although still has this issue to a certain degree! But. It has some backlight bleeding at bottom whereas the other has none!! I have them both side by side on my desk at the moment trying to do a migration. Very unsuccessfully I might add! I know a lot of people will advise me to exchange again until I get a perfect one. But I just really can't be bothered and the way I see it nothing in life is perfect and I might get an even worse unit! I keep switching between the 2 and am leaning towards the newer one with backlight bleed. As it is only really noticeable on black backgrounds, playing movies with black bars top and bottom! Whereas I will mainly be looking at white backgrounds. Safari, calender, email etc. and it was very distracting when moving around the screen! I was just wondering if anyone had a similar quandary. Or could give me their thoughts. Well actually. Make my mind up for me!!
