Assembled new computer March of 2019. Installed Win 10 64bit and fired up Samsung 4k monitor. Had flashing issues with monitor. Updated drivers for Motherboard and AMD Ryzen 5 2400G, new HDMI cable. Monitor had no issues, until I was informed the a new AMD driver was available. I updated and the flashing problem returned. I did the motherboard update and the AMD update and still had issues. I loaded the AMD drivers from July and the problem seemed to go away. Now when the computer goes into sleep mode, I wake it up and the display flashes and goes black, unless I restart the computer. Then it seems to function fine, until it sleeps again.
So the combination worked for 9 months and when I did an update it started with the flashing screen issue. I have tried going back to the old drivers, but that didn't seem to work. Right now I have the new Gigabyte driver installed and the AMD driver from July. Any ideas?
Thanks!!
