I am connected with my MacBook Air M1 but I can't get resolution higher than 1920x1080 (also after pressing option+scaled). I am connected on HDMI via the Dell multi-adapter (https://www.digitec.ch/de/s1/product/dell-usb-c-zu-hdmi-vga-usb-a-dockingstation-5668957). Should I change cable? Helpez moi please :(
Issue can be due to several reasons. I imagine you have an outdated/old HDMI cable (version <1.3).
If you have a sufficiently newer version of HDMI cable (say HDMI 2.0), then perhaps its the dell usb-c adapter. Product description does not say thunderbolt, so it's only USB-C. Plus Apple is not among list of compatible brands. Is 1080p is the max you can get with all other slots unused on the dell adapter?
