I was thinking about getting a 2560x1080 wide screen monitor but will certain games even run at this resolution? and what will happen to videos or movies running at 1920x1080
If you're referring to those new Super Wide Screen Monitors... I'm WITH YOU. I've been thinking about grabbing one myself. It's true that some games aren't designed for that particular aspect ratio... BUT that is only because it's only now becoming mainstream. Expect all popular games coming out to pretty much support it and a few older ones to have patches or "workarounds" created.
As far as movies... yes, you could have black bars... but I think it's possible for movies and shows to support this ratio very soon. Remember when regular widescreen came out.. almost everything was square..
But getting back to games... playing a game at this aspect adds a new level.. or I'm told. Since I'm an AMD user, I've decided to get an LG monitor since they support FreeSync and seem to have the best prices.
