2048x1536 is the max res support by the GF2MX, not the card.
Plus, i notice that sometimes the OS matters too. WHen my radeon was in WinME. The res only goes up to 1600x1200.
But now in Win2000, it goes up to 2048x1536. So it can be OS limiting the res, or the card is limiting it.
But, if u set the res up to 2048x1536, the task bar and all the icons will shrink so bad that u can barely see it. U will need aleast a 22" monitor to make it useful.
