Hi,
I built a PC about a month ago and the last few days, my main monitor would disconnect (go black and display only "DisplayPort"), then my screen switches to my secondary monitor, then back to my primary (when it turns back on after a few seconds). Basically, my primary monitor acts like it was just unplugged for a few seconds. Both monitors are identical, other than primary having V sync. It happens 90% of the time when waking the PC up from sleep/lockscreen/etc. It was happening during use a few days ago, but is doing it less now. I have uninstalled and reinstalled drivers for my graphics card and changed the DisplayPort cable. I've restarted the monitors.
CPU: Intel Core i5-10400F 2.9 GHz 6-Core Processor
CPU Cooler: Cooler Master Hyper 212 EVO V2 62 CFM CPU Cooler
Motherboard: Asus ROG STRIX B460-I GAMING Mini ITX LGA1200 Motherboard
Memory: Corsair Vengeance LPX 16 GB (2 x 8 GB) DDR4-3200 CL16 Memory
Storage: Samsung 970 Evo 1 TB M.2-2280 NVME Solid State Drive
Video Card: EVGA GeForce RTX 3070 8 GB XC3 ULTRA GAMING Video Card
Case: Cooler Master MasterBox NR200 Mini ITX Desktop Case
Monitor: 2 x Samsung CJG54 27"
Any help would be greatly appreciated. Cheers.
