I have a Radeon 9000pro supporting two monitors. Here are my questions.

1. I want both monitors to have 1280*1024. However the secondary monitor always turn out to be 1024*768. Does 9000pro not support dual 1280*1024?

2. My opengl program runs well on single monitor. But when I set the window size of two screens, the program goes intolerably slow. What's wrong?

My questions might be quite basic. Thanks for patience.

i am assuming that the 2nd monitor is either identical to the first or capable of supporting that res at a given refresh rate? if not, that could be the problem.

stretching the windows makes the gfx workload increase since it now has to process more pixels. so i am not surprised about it slowing down a bit when you stretch to 2 screens
