RX 6700 XT black screen crash only in Diablo – driver breaks until DDU reinstall (dual monitor)

Hey everyone,

I’m running into a really frustrating issue and I’m trying to figure out if this is a known problem or something specific to my setup.

System:

• GPU: AMD RX 6700 XT
• OS: Windows 11
• Dual monitor setup with DP (different refresh rates 165/144 Hz)

Issue:

Everything works perfectly in general, including other games (Rocket League runs completely fine).

However, when I play Diablo IV, after some time (not always immediately), I get:

• One screen goes black and suddenly the PC freezes
• Audio continues (system still responsive in the background, even if Im on a call it keeps going )
• Driver reset (Ctrl + Shift + Win + B does NOT recover the display
• I’m forced to hard reboot

After reboot:

• Only the secondary monitor works
• Primary monitor stays black / not properly detected

Only fix so far:

• Boot into safe mode
• Use DDU
• Reinstall AMD drivers

After that, everything works again… until it crashes again in the game.

What I’ve tried:

• Clean driver installs (DDU multiple times)
• Different driver versions (not just the latest)
• GPU stress tests → no crashes, no artifacts
• Temps are fine (~60–70°C under load)
• Other games work perfectly

Important detail:
This ONLY started happening after going back to Diablo. Althought the first time it happened was playing ALSO Diablo a couple of seasons ago.

Logs:

• Event Viewer shows nothing related to GPU crashes
• Only Kernel-Power from forced shutdown

Has anyone experienced something similar?

At this point it feels like some kind of driver/game interaction or multi-monitor issue, but I’d really like to avoid having to disable monitors or limit my setup just to play one game.

Any help or similar experiences would be really appreciated.
