I have a S21 updated to latest Android.
I know it will work on Dex pad but not all of us need a dexpad.
Laptop connected to ultrawide monitor works in ultrawide, running Dex on laptop won't go in to ultrawide.
Ive used hdmi adapter to usb c & cannot get the ultrawide to work on my ultrawide monitor.
Even using a 4k HDMI cable doesn't work.
Samsung please fix this!
