2nd monitor goes black while gaming something like Battlefield 1 or Pro evolution soccer 2019 or something else. I play on one display but 2nd I use to monitor CPU GPU RAM performance graphs. I use for it MSI Afterburner. Few months ago everything worked well, but now it just goes black. When 2nd monitor is black the light (turn on/off) is on (not blinking). Is there any option make both screens don’t go black while gaming? Something like in NVIDIA control panel? PC: i7-4770k Geforce GTX 960
