Hi
I brought the P2715Q monitor couple weeks ago, and connected it with my Mac pro via DP to mDP cable, and everything was working great. One day I brought a computer and wanted to connect it with my monitor so I do not need disconnected everything. Then there is a problem come out: When I connected the computer with my monitor via VGI to DP cable, it always showed " Entering Power Saving mode" and after I changed to HDMI to HDMI, the monitor did not show anything up, and I already spend much money to buy different cables and none of them works. Therefore, what should I do to make it work.
And there is my computer's information:
