  • AMD Graphics Card:  Sapphire Pulse 5700 XT (100416P8GL)
  • Desktop
  • Windows 10 64 bit (1903)
  • Driver installed:  19.9.2
  • Monitor 1 (Displayport): Acer XFA240
  • Monitor 2 (HDMI) that won't go to sleep: Asus VS239
  • Motherboard:  MSI B450 Tomahawk; Bios version: 1.A0
  • CPU:  Ryzen 9 3900X
  • Power Supply:  EVGA SuperNOVA 850 GS 220-GS-0850-V1 80+ GOLD 850W
  • RAM:  32GB DDR4


  • When Windows puts the monitors to sleep due to inactivity, my Asus VS239 (HDMI) does not go to sleep mode, it just blacks the screen out but it remains on.  However my Acer XFA240 (Displayport) does go to sleep mode.  I had no issues like this with my Geforce 2070 that I had prior.  I used DDU to fully remove the Nvidia drivers before installing my new 5700 XT.  Also for troubleshooting I tried using DDU to fully remove the AMD drivers and reinstall to make sure it wasn't a corrupt driver install, but the issue persists.
