Ryzen 5 2400G Display flashes after update

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?
