My PA32UCX-PK shows a very strange behaviour. If I connect my Apple TV 4k A2169 to HDMI2 of the monitor, Apple TV only sees 1920x1080 SDR as the max resolution. If I connect it to HDMI3, it detects the monitor as 4k Dolby Vision capable.
Is this a known behaviour? Are the HDMI ports in any way different?
Thanks for any hints.
