Hi!
I recently installed a sapphire Radeon RX 580 GPU in my desktop PC.
Through HDMI I connected two (identical) full HD monitors.
When i try to play a game (for example, Sims 4) in full screen mode (on one monitor) the screen flashes wildly, different colors appear with each flash, like the GPU cannot handle it. If I close the game, the wild flashing stops, but now and then (roughly once a minute) a single flash appears. If I restart the PC, everything works as it should (until I load a game). The problem seems to get worse if there are more moving parts on the screen.
If I play a game in windowed mode, there is no problem at all. When I remove the HDMI cable from my 2nd screen, everything works as expected even in full screen mode.
I didn't test this with the Sims in-game, the problems already start in the main menu.
I cannot capture these "flashes" with ReLive. In the recordings it all looks normal.
I'm wondering if this is normal behaviour for a brand new GPU, or if there is something wrong.
- should I be able to play a game full screen on one monitor, while the other screen just shows windows desktop?
- could my CPU be the problem? (Intel i5 6402P)
Thanks in advance for your reactions!
