What is your current screen resolution? Mine is 1024x768, I've used larger displays in past but I've noticed that most of that space is usually empty and I prefer information density. 1024x768 was also the standard when most of the software I use was made, so things tend to fit neatly.
ideally, I would have some kind of crazy 600hz screen, but I play rhythm games and thus actually do need the extra framerate so notes don't just jump down the screen in big, hard to read steps when I increase my scroll speed
when my trinitron was still working i used 1280x960@90Hz, then the green gun gave up the ghost, and now i'm stuck with a 1024x768 LCD and i absolutely hate it, because i don't know how to fix the trinitron. 16:9 just feels wrong to me now.
>>11 16:9 is cool for watching stuff and work but 4:3 is perfect for everything else The web alone has never looked good on a 16:9 screen To the point where modern websites are either zoomed in (which looks terrible) or have borders. For games, it depends. I'd say only FPS are worth playing on a 16:9 screen (except maybe the older ones like Doom ).
