Thank you Daniel; I've installed kernel version 6.0.3, but it does not appear to have substantively affected the issue



b.p.

 Given you CPU is relatively new compared to the kernel version I suggest
trying a newer kernel like

  sudo apt install linux-image-6.0.0-1009-oem

or something from https://kernel.ubuntu.com/~kernel-
ppa/mainline/?C=M;O=D

Title:
  [i915] Kernel cannot detect HDMI connection

Status in linux package in Ubuntu:
  New

Bug description:
  xrandr lists four disconnected DPs (though my laptop has zero Display
  Ports) but does not list an HDMI, which is what I use to connect
  external monitor. Cable is sound b/c I have a dual boot setup and
  Windows recognizes the display without issue.

  Using Ubuntu 22.04.1 LTS
  I expected OS to recognize that I have a an HDMI port or alternatively that something is plugged into it
  OS does not seem to acknowledge same
