Waking your PC from sleep to find a black screen with your AMD GPU is a long-standing issue that has affected RX 5000, 6000, and 7000 series cards. Your PC fans are spinning, RGB is on, but the monitor says 'No Signal.'
How to fix it:
- Disable ULPS (Ultra Low Power State): open Registry Editor, search for 'EnableULPS', set every instance to
- ULPS puts the GPU into a deep sleep that it sometimes cannot wake from
- In Windows Power Options > Change Advanced Power Settings > PCI Express > Link State Power Management: set to 'Off' for both battery and plugged in
- Disable Hybrid Sleep: Power Options > Advanced > Sleep > Allow Hybrid Sleep: Off
- If using DisplayPort, try switching to HDMI temporarily. DisplayPort link training after wake is a known failure point on AMD GPUs
- Update your monitor firmware if available — some monitors handle AMD wake signals poorly
- In AMD Software > Graphics > set all power-saving features to disabled
- As a nuclear option, disable sleep entirely and use hibernation instead, or just let the display turn off while keeping the PC awake
- Check your motherboard BIOS for any AMD-specific sleep/wake settings
