By default, the GameHub remains powered to keep your spare battery fully charged, which is why the OLED screen stays on.
To manage this, you can either:
Set a Screensaver:
Press and hold the volume dial → System Settings → Display → Screen Saver. Choose your preferred mode and timeout (1–60 minutes, in 5-minute steps). This lets the OLED dim or turn off after inactivity while still charging your headset.

Enable Power Saving:
Press and hold the volume dial → System Settings → PWR Saving → On. This turns the OLED off completely when your PC or console is off. Note: charging will only occur while the connected device is powered on.

These options were added to help prevent OLED burn-in and to give you flexibility in how your GameHub behaves.
GLHF!
