After updating my M1 Mac Mini to the latest macOS Sequoia 15.2, my QHD 2K monitor now only allows display resolutions of 1920 x 1080 and 1280 x 720 (default). Previously, macOS allowed me to use
2560 x 1440. How can I revert to the 2560 x 1440 resolution again ? Thanks in advance.

If you are using the long cheap ViewSonic supplied HDMI cable.
Test a short high speed HDMI cable > https://www.amazon.com/dp/B09J55JYN9/ref=sspa_dk_detail_1?
or short high speed USB to DisplayPort cable > https://www.amazon.com/dp/B09J55JYN9/ref=sspa_dk_detail_1?
Use the option key when opening the display settings and see if any others are shown.
Just tried..only changing the [Night Shift..] to Detect Displays.
Click detect display nothing happen.
What brand and model is that display..?
How is the display connected the the Mac mini..?
VIEWSONIC -VX3276-2k-mhd with HDMI cable.
Finally get the new cable, doesnt seem to work.
