We are sorry that we do not always have the capacity to review all
reported bugs in a timely manner. You reported this bug some time ago
and there have been many changes in Ubuntu since that time.
Ubuntu 16.04 (xenial) reached end-of-standard-support on April 29, 2021.
Do you still see a problem related to the one that you reported when
using a currently supported version of Ubuntu? Please let us know if you
do otherwise this report can be left to expire in approximately 60 days
time.
Thank you for helping make Ubuntu better.

Title:
1920x1080 HDMI output is corrupted in 16.04
Status in xorg-server package in Ubuntu:
Incomplete
Bug description:
Ever since upgrading to 16.04 from 14.04 on my Lenovo x230 the HDMI
output to a Benq W1070 is corrupted if run at 1920x1080 (native
resolution). At 1280x720 the display looks fine. Looking at similar
reports for other graphics cards it seems similar to cases when the
frequency is too low. I've tested that the projector still works fine
with the same cable and another computer. I've attached a photo of the
kind of corruption that shows up on screen. It's mostly green/magenta
pixels sprinkled across the screen.
