1720 * 720 (hidpi) not working with Big Sur #36

Hi! I recently updated my MBP 13inch from Catalina to Big Sur. 1720 720 (hidpi) worked perfectly with my Dell 3419W with Catalina. However, it did not work with Big Sur. I could find 1720 720 with the flash in the menu, but nothing happened when I clicked on it. I tried this workaround #23, but it did not work for me.

System: MacOS Big Sur RDM version: 2.5.0 Monitor: Dell 3419W

I had this issue and got it working by removing any of the files in /Library/Displays/Contents/Resources/Overrides/DisplayVendorID-10ac/ (Dell monitor). Then creating an entry from Edit... with only Retina & hidpi checked, rebooted. Choosing 1920x1080 hidpi worked (where previously nothing would happen).

Running into this problem trying to set my 16:9 screen to 1600x900. The above method doesn't work for me.
