samsung are famous for the back light bleeding.
my syncmaster 2494hs 3years old now has back light bleeding right around the outer edge traveling about an inch in. its not that noticeable but it is there... better try a different brand.
dell ultra sharp are some of the best, a m8 has 1 and its a very nice crisp led back lit screen.
my much cheaper but newer lg on the other hand is much crisper in colour and has no back light bleeding. i dunno if samsungs new led panels have the same issues today but to be honest i am less than impressed by there overall standard of quality...
a brand to stay well clear of are hanns-g there monitors last about 18 months and the power brick goes. i had 2 returns in the warranty period and the 3rd died 8 months after the inital 2 year warranty ran out. all 3 went with the same issue. also they do not honor there dead pixel warranty return. i had 2 dead pixels within 1 inch in the upper center of the screen and a 3rd at the edge, they refused to rma it because all 3 were not within 2 inches of each other. while there warranty said if you have 2 dead pixels they would replace the screen... that wasnt the end of it. each rma took weeks. the first took about 5 weeks from first email to replacement, the second took a week less and the third took nearly 2 months. never again will i buy or recommend a screen from them... they may have a good rep in Europe but in the uk it sux...
