I have a MacBook Air 2017 (Dual-Core Intel Core i5) and a Samsung curved display (34” ViewFinity Ultra WQHD High Resolution Monitor with 1000R Curvature -Model : S34A650UXN) that used to display fine using a J5 JUD380 dongle to go from the USB A from MacBook to dongle.
The dongle is connected to the Samsung monitor via a HDMI cable.
Before I shared screen with a 3rd party during an IT session, my screen displayed beautifully.
After I ended that session, I delete the software (don't recall what it was) and maybe an additional plist file(s).
Now my display is stretched with resolutions options limited at 1920x1080.
I have reset the monitor 3 times, and reinstalled OS (currently Montery 12.7.5 beta) 4 times. I deleted the NMRAV.
I have tried a different dongle, and tried 3 different HDMI cables.
I'm out of ideas and I am NOT a techie - please help!
