Hello,
Can you hold down Windows +R keys, type in mmsys.cpl and press enter. In the pop up, do you see the monitor listed? If so, do make sure it is set as default device.
If above settings is already correct, can you share with me two screenshots please?
- Go to Device Manager > Display Adapters, I would like to see what's listed.
- Please type msinfo32.exe in the search on the taskbar and hit enter, then share a screenshot of the pop up.
Thanks!
