I have come across a Samsung 2233SW+, the same as this but with a higher contrast ratio and 1920x1080. I was actually just wondering if it would downscale to 1680x01050 as my 9800GTX+ won't cut some games with high AA/AF with VSync.
My old 9800GTX used to run most things fine at 1920x1200 with no AA.
You don't really need AA when you're running HD and on the 22" screen most things will look sharper anyway!
