Check for Hardware Issues

If none of the above solutions work, there might be a hardware issue. Here are some steps to diagnose hardware problems:

1. Test with Another Monitor

If possible, try connecting your ASUS ROG Ally to a different external monitor. This will help determine if the issue is with the monitor or the device.
