It also depends on the video card you are attaching it to and what you are using it for ...

if you can find drivers for it i dont see why any kind of monitor cant do it, i can force my ENViSION monitor up to as high as 1900x1080x32@60 and down to as low as 320x280x32@220 useing my ATi Catalyst control panel.
