Asus 21.5 in VE228 Monitor

Hey all, so I have this monitor as described in the title, the Asus 21.5 in Ve228. It has been a good monitor so far (2 months), but as of late I am noticing more and more light coming from all sides of the screen. You can see this white light especially when watching a movie with dark picture. I plan on upgrading my display setup to three monitors in nvidia surround quite soon. Question is, is this white light from all 4 sides of the screen normal with a backlit monitor? And, will this be a good model to use 3 in snync for gaming? Please let me know as it is a very affordable HD monitor and I would hate to get 3 whole new monitors if I dont have to. Thanks for the help,

Justin
