Do any of y'all experience a lot of screen-tearing in your games? What resolutions look best to everyone?
I get a bit of noticeable tearing, but I don't think it's my monitor (Samsung 24" Syncmaster 244T). I don't notice tearing at 1920x1200 on my PC games on the same monitor, but when I run my 360 at 1280x1024 over VGA or 1080i over component, I get noticeable tearing in NBA 2k7 and Oblivion.
Since games render to the 360's framebuffer in 720p, it seems like this should be the best choice as the other resolutions require upscaling from the box. I'm wondering if your games look best in 720p.
Of course, frame by frame, the cleanest picture is over VGA, but the tearing is impossible to ignore over it.
