Driver version 9.003.3.3
I create a 4x1 display group @1920x1080 and then enable a 5th output @1920x1080 as extended. Works perfectly.
I create a 5x1 display group at 1920x1080 and then try to enable a 6th output as extended - does not work. It even leaves the driver in a bad state which prevents any extended display from working correctly without driver removal and reinstall.
Anyone else had similar?
