Some guy on this forum has a set up like that but used 20" widescreens for the secondary and tertiary screens. It look really cool. In portrait mode they will be 1680 pixels vertical---very close to the 1600 of the 30".
Thanks. Did not think about the vertical pixels. So if I went with a Samsung 27" Widescreen (275T) (1920x1200) it would make sense to use maybe a Samsung 19" Standard (940BX) (1280x1024). The 1200 and 1280 are close. I assume the horizontal pixel count doesn't really matter. Getting ready to buy now that the new 8800gt is out. Thanks.
