I'm facing a seriouse issue with 4K resulaution on Dex mode.
I have a 4K TV ( LG b7 ) + 4K cable + USB hub support 4K ( from 3d barty )+ S10e using the last update.
but still unable to run Dex on 4K as below snapshot shows.
The display on the S10e is too small to support higher resolutions so it can only support up to 1080p by max only
i am talking about dex mode resolution
