[Nouveau] NV130 - gtx 1050 ti

[Ilia Mirkin]

First things first -- I've alluded to this before, but let me be clear
-- there is no global database that contains monitor-specific
information which is used by any linux drivers. Please forget any
notions you had of such a thing existing or being used.

The information comes from the EDID blob supplied by the monitor.
Presumably hwinfo has a primitive EDID parser, which is where that
information comes from. A more complete EDID parser is available at

https://cgit.freedesktop.org/xorg/app/edid-decode/

For example,

$ ./src/edid-decode/edid-decode /sys/class/drm/card0-DVI-D-1/edid

Prints the full EDID information for the monitor connected on that
connector. Note that some monitors require special settings in order
to expose the higher resolution modes, and others only make them
available on some inputs but not others. No idea if yours is that way
or not.

It's quite likely that nouveau doesn't support using YUV outputs
though (which I'm guessing is what the 4:4:4 thing is referring to...
I always get confused by such notation), only RGB. Also there's no
HDMI 2.0 support in nouveau as yet, mostly due to lack of interest and
hardware. However you should still see a 4k at 30 mode exposed
(probably).

Cheers,
