5700xt flashing black screen, rainbow snow, audio popping

Summary of Issue

A couple of times per week, my monitor (a 4K TCL TV connected via HDMI) will simultaneously do a few things: (1) alternate flashing a black screen and a "rainbow snow/noise" pattern with (2) violently popping audio--the kind of popping you might expect when you're plugging an audio cable into an amp that's on really loud.

The screen will continue to flash black and show this rainbow noise pattern and continue to make popping noises, intermittently displaying the desktop and being calm for 10-15 seconds, before going into another fit.

Each time this happens, a restart fixes the problem and it does not come back for multiple session. Today it happened after a wake from sleep--unclear if that is related, but it felt important to call out.

What this is not: "flickering" or low FPS. I wouldn't describe it as a "permanent black screen". I have not let it happen for long enough to figure out if it shuts down/restarts the computer by itself. I have never seen a BSOD due to this issue. This does not seem to happen exclusively while playing games and, so far, does not seem to be triggered by anything in specific. Temperatures are typically low while this is happening (not running anything intense).

System Configuration

  • Motherboard: ASUS ROG Strix B550-i GAMING

  • CPU: AMD Ryzen 5 3600

  • PSU: 650W SFX-L 80Plus Gold (stock in NZXT H1)

    • TCL 55" P6 Series 4K UHD TV (55P605)

  • System Memory: Corsair Vengeance 16GB DDR4 3200MHz

  • GPU (VBIOS): Sapphire NITRO+ Radeon RX 5700XT (Driver version:

  • OS (Version): Windows 10 x64 (Version: 19041.388)

  • Driver: Radeon Software 2020.0711.1742.31878

  • Applications: No specific apps affected

  • Background Apps: Typical background apps include Steam, Spotify, but do not seem to be related.

  • Radeon Software Settings: Chill ON, Image Sharpening ON Antilag OFF Boost OFF Enhanced Sync OFF, FreeSync OFF, GPU Scaling ON, HDMI Link Assurance ON

So far, I have not been able to determine how to reliably reproduce this.
