Dear Hale,
This is a known Windows 11 kiosk/always-on display issue — the display output driver or connected monitor goes into a low-power state and fails to wake, even though the PC is still logged in.
Fixes that actually work and stop it from happening:
Disable all display sleep/turn-off timers
Settings → System → Power & battery → Screen and sleep → Set all to Never.
Also disable screen saver.
**Force GPU to keep output alive**
In GPU control panel (Intel/NVIDIA/AMD), disable adaptive power saving for the display.
For NVIDIA, set **Power management mode** to **Prefer maximum performance**.
**Disable “Fast Startup”**
Control Panel → Power Options → Choose what the power buttons do → Uncheck **Turn on fast startup**.
**Use “Presentation Mode”**
Run `Windows + P` → Extend or Duplicate as needed, then enable **Presentation Settings** (`presentationsettings.exe`) so display never blanks.
**Update graphics driver & firmware**
Install the latest GPU driver directly from Intel/NVIDIA/AMD, not just Windows Update.
If using a display hub or extender, update its firmware.
**If still intermittent** — turn off **Hardware Accelerated GPU Scheduling** and/or **Variable Refresh Rate** in Settings → System → Display → Graphics.
Most kiosk deployments stop this issue by combining #1, #2, and #4 so Windows never tries to power-save the display.
Best Regards,
