17" LCD's use 1280x1024
so essentially, your comparing between a 17" version of a resolution to a 19", stretched version.
i chose 17", and i am happy
i own the samsung 730b and its a great monitor
i'd much rather an 8bit panel, but those are more expensive and not so great for gaming yet, but i think the samsung 970 is supposed to be a good performing 8bit model
in case you dont know, 8bit is more accurate color (16.7m colors) compared to 6bit (something around 260k+ colors, about 16.2 after dithering)... my panel produces some color banding, but all 6bit panels do
