Hello, I have recently got a second monitor from a friend, and connected it via DVI to my Graphics card (AMD Radeon R290) next to my old monitor (both monitors are plugged in the same graphics card) Everything worked fine, but now when I turn on the PC, the new monitor wont light up, the powerbutton does nothing, all other buttons do nothing, BUT the monitor is on, I can do stuff on it (drag the mouse on there, open a window and drag it to the working screen etc.) When I restart the PC over and over, eventually the monitor does turn on, but it seem completly random. I checked the powercord, exchanged the DVI cord with a HDMI cord, but nothing helps. I think the monitor just doesnt get the signal to turn on the light but virtual it is there. Should I try to reinstall the graphics card driver? Or is the problem in the monitor?
