I'm trying to use 3 monitors with a AMD5970 card. The monitors are pretty basic syncMaster 943N 20" with a max res of 1280 x 1024.
The problem is that the monitors won't extend to the monitor coming from the mini display port. That monitor shows up as a non generic pnp monitor whereas the other two show up as SyncMaster. It did seem to work initially for about 30 seconds but the minute I tried grouping them.....it stopped! And won't revert back. Now if it shows up at all it shows up with a resolution of 640 x 400!
