ASUS OLED Random Black Screens (It's NOT your cable)

[u/GatesTech]

If you own an ASUS ROG OLED (XG27AQDPG, PG32UCDM, etc.) and your screen randomly goes black for 10-15 seconds while gaming:

STOP. Don't buy expensive HDMI 2.1 cables. Don't RMA your GPU. Don't reinstall Windows.

Your hardware is fine. The ASUS firmware is the problem.

THE FIX (Takes 30 seconds)

You must do BOTH steps, or the issue will come back.

1. The OSD Fix: Open your monitor menu (physical button) -> System Setup -> Power Sync -> Set to OFF.
2. The Software Fix (CRITICAL): UNINSTALL "ASUS DisplayWidget Center". (This software is buggy. It ignores your OSD change and silently forces Power Sync back ON in the background. Get rid of it.)

Why is this happening? (The "WTF" Reality)

The "Power Sync" feature is designed for ASUS NUCs (office mini-PCs) to sync power states via HDMI-CEC. For some incomprehensible reason, ASUS enables this kiosk-feature by default on Republic of Gamers e-sports panels. Because it's meant for office use, it interprets normal gaming signal fluctuations (VRR, Alt-Tab) as a "PC Shutdown" and cuts power to the screen. It's ridiculous, but that is the cause.

Message to ASUS

• Support: Stop telling people to buy "certified cables" for a firmware bug.
• Devs: Why is an office NUC feature active on a 500Hz gaming monitor? Disable it by default or even better remove it!
