Not that i'm necessarily agreeing with ThatGuy, but i do have to disagree with some of the things you're saying.
They aren't. Steam survey says < 30% of monitors are 1080p or higher. Most popular resolution is 1680x1050, with 1920x1080 and 1280x1024 just behind. And that's a survey of gamers, which is almost certainly going to be biased towards people with nicer than average hardware.If it isn't there ask your self why is it that a majority of TV's and monitors are 1080p nowdays?
I know all of your hardware is 1080p, and that you do all sorts of fancy DVR stuff on your machines, but you shouldn't then assume that everyone else must be doing the same thing.
