System: Windows 8.1
Graphics Card: AMD FirePro W7000 (Max Resolution 4096x2160; 4 DisplayPorts)
Purchased a new P2815Q monitor, which should support up to 3840×2160 (4K), but the max resolution is only 1920x1080 now.
The monitor should support DisplayPort, Mini DisplayPort, HDMI and even USB, right? But why does my monitor only outputs to HDMI cable?
Anyone knows how to solve it?
