I am running a 21" color graphic monitor at 1,200 X 800 pixels and it still goes off the end quite a bit. It is not a matter of resolution on the monitor, graphics card, etc, it is due to the absolute number of pixels in the image and the number of pixels the monitor is set to run at. Since there are so many different monitors out there, all pictures should be posted at 640X480 pixels at 72 dpi.
