Title:
HP Envy 34c resolution maxes out at 1920x
Public bug reported:
Using get-edid, the best resolution is "Mode 0" below, but this doesn't
show up in the Display systems settings panel.
This is read-edid version 3.0.2. Prepare for some fun.
Attempting to use i2c interface
No EDID on bus 0
No EDID on bus 1
No EDID on bus 2

The only way to get a workable system is to move back to a 4.4 kernel. I
tried that before and still experienced some issues but trying this
latest 4.4 build.

Weird yes! Thanks for the feedback though. I'm on the 4.4 kernel now
and wanted to report this which is perfect. I'll switch back to the
stock linux-generic in a bit to run the same and post the output here if
that helps.
