I was over at a friend's house earlier tonight trying to test out his new 5850 Eyefinity setup in portrait mode with 3x Dell P2210H monitors. They have DVI and DisplayPort on them. I had two hooked up via DVI and the third hooked up through DisplayPort. However, when I tried rotating the picture to portrait mode, whether I was in grouped mode or extended desktop mode, the option was not available to rotate the picture. It would only let me work in landscape mode.
When I turned off the DisplayPort connected monitor, the other two would automatically adjust to two monitors, and then it would allow me to switch the two DVI connected monitors to portrait mode. Once I turned the DisplayPort connected monitor back on, all three of them would switch back to landscape mode, and I would be back where I started.
This is on the newest 10.2 drivers.
Anyone had similar problems? Solutions?
