<pre>Just tried Kernel 4.8 from latest Ubuntu Zesty daily build and seeing some
(new) issues:
1. Using the HDMI port to the left side of the DisplayPort port (which is the
HDMI port that is being powered by the MegaChips MCDP2800 LSPCON), Broadcast
RGB suddenly is automatically being set to Limited 16:235, even though it's
connected to a DVI-D PC monitor via a passive HDMI to DVI-D cable. This is not
the case with Kernel 4.4 from Ubuntu Xenial. With Kernel 4.4 from Ubuntu
Xenial, it's properly being set to Broadcast RGB Full. So, this seems to be a
regression between Kernel 4.4 and Kernel 4.8.
2. Plugging the same monitor with the same cable into the HDMI port above the
DisplayPort, the monitor stops receiving a signal once KMS kicks in (it goes
blank and goes into standby).
Why is that? Could you please fix those issues?</pre>
