I can't figure out if I should buy this 20.1 inch widescreen monitor. It would be a perfect fit on my desk BUT I need to figure out if my X1800GTO will support it's native display of 1650x1050. I can't seem to find any info on what my card can support and when I check what resolutions are available now, with "hide modes this monitor can not display" unchecked, I can't find 1650x1050. Does this mean its not available on the card?
