I am looking to buy a 19 in. widescreen LCD. It has a native resolution of 1440X900. How can I verify that my graphics card can meet that resolution. One computer has a Radeon X800GTO AGP card and I think it might work, although the highest resolution listed is 1280X1024. The other computer came with on board graphics which has been discontinued in favor of a EVGA FX5500 PCI solution. How can I tell if these cards will work.
