What would be unsatisfactory about it? I thought maybe low response time, but if it would blur games, it seems like it would blur movies, too. Maybe they only refresh at 30Hz or something... but being a LCD it wouldn't flicker, and I'm lucky to get 30 FPS out of most games anyhow.
It is simply the fact that most software doesn't support 1280x760 or whatever weird resolution these things have? [edit: 1280x720] I'm sure you could customize an X server with that resolution. But what would happen if a Windows app tried to go into fullscreen 1024x768 DirectX mode or something?
