So I've had a r9 270x for 2 years now, and since the first day i've had it it hasn't supported more than two monitors at once despite being advertised to support 4 displays at once.
Problem: I fixed this problem by enabling igpu in bios, and installing the Intel drivers. I managed to get 3 monitors to work! However this causes a problem with photoshop. I use photoshop constantly, but it crashes becasue it cant use either amd, or intel drivers. If I get rid of the intel it works, but them I only can use 2 monitors.
Facts: The gpu has 1xdisplayport, 1xhdmi, and 2xdvi. I have it using hdmi, and displayport on the gpu. The third, dvi, is on my motherboard. When I have all three in the gpu it says "disconnect this display" and setis it at 800x600. If I set it to "Extend this display" and hit apply, it says "Unable to save display settings"
Any body know what to do, because i'm stumped :/
