So I'm just about to buy the parts to build my first PC. One of my friends recently bought the Dell SX2210 (a 21.5" 1920 x 1080) for his custom PC and I saw it and fell in love. I wanted to spend around $200 for a monitor and I wanted it to be glossy. I went to buy the SX2210 for $189 but I noticed they have a 23" 2048 x 1152 (SP2309W) for sale for $209. I calculated the pixel density to be about the same for both, and the price per pixel is slightly cheaper for the 23".
What I want to know is, is there any advantage over the higher resolution? The graphics card I'm buying can definitely support this resolution (HD 5750), but will watching HD movies be stretched or messed up?
I love the idea of higher than full HD for gaming but I don't want HD movies and such to be LESS quality than with 1080p.
I'm trying to buy a monitor tonight so any help would be really appreciated!
