Dell D3100 - no 4K resolution available

Hello,

I missed your message the first round when I was away.

The resolution offered is the maximum of HDMI.
I believe the DP->HDMI adapter you are using is a passive adapter. Therefore it uses the DP++ feature which is, in simple terms, HDMI signals over the DP plug.
https://en.wikipedia.org/wiki/DisplayPort#Dual-mode

I suggest you get an active DP -> HDMI adapter so what is going through is actually DisplayPort and not HDMI.

Kind regards,
Alban
