Public bug reported:
After "original Ubuntu 16.04 LTS" installation on my
Intel® Pentium(R) CPU G4400 @ 3.30GHz × 2
Intel® HD Graphics 510 (Skylake GT1)
System with UHD TV (3840x216@30Hz)
Philips 49PUT4900
everything seemed fine. The resolution was totally ok with 3840x2160@30Hz.
Without further installs (no known updates or so, beside the OpenSSH Server
install) it falls back after a while to FHD (1920x1080) without option to
switch back.
It seems that the original installation recognizes all parameters as needed
from the TV, but afterwards at some point it cannot.
Several reboots of the system after the original installation it works still
fine, but from one day to the other it is wrong.
Additional information:
1.) I use an adapter cable converting from DP to HDMI (I have no DP monitor
available).
2.) I already tried to start without a monitor connected and then connect
3.) I already tried to disconnect and then connect again (after 15sec.)
4.) Now I have upgraded everything with "apt-get upgrade"
All without changing anything.
Result from "lsb_release -rd"
