Hi @Cheeseman442 ,

Thank you for contacting ASUS support.

Regarding your issue with the USB ports on your PG34WCDM monitor, where the system displays a message stating that the USB device may not function properly when connected to USB 3.2 or red USB ports, but seems to work on regular USB ports, here are some troubleshooting steps you can try:

Update drivers:

  • Display driver: Check and update your display driver to ensure it is compatible with your Windows version.
  • USB 3.2 controller driver: Ensure the USB 3.2 controller driver is up to date.

Power management settings:

  • USB selective suspend: In Windows power options, check if USB selective suspend is enabled. If enabled, try turning it off to ensure USB ports are always powered.
  • USB power management: Check the USB power management settings on the monitor itself.

USB port malfunction:

  • Replace the USB device: Try using a different USB device to see if the problem is with the USB port itself.
  • Replace the USB cable: Try replacing the USB cable to rule out a cable fault.

If the problem persists after you have tried the above steps, we recommend that you bring your monitor and all the included cables to the nearest ASUS service center for inspection by a professional engineer.

Thank you.

Please note that response times may be delayed due to upcoming regional holidays. For urgent inquiries, please contact your local service center. Thank you for your patience.

So I have tried updating stuff and whatnot (it is a brand new PC so everything was uptodate) 

 

Looked at my ports and it says there is an unknown usb device (port reset failed) (Code 43) so i dunno if that is the monitor or not

 

Checked settings on monitor but no clue how to change power settings for monitor in monitor settings. I have seen online that there are other people experiencing this issue.

 

Have tried differnt ports and cables

 

 

 

The other info you requested, I am not sure how to get so if you could tell me that would be amazing

Also am I able to have the firmware update for the monitor as I cannot find it online
