After coming out of suspend the display is not receiving any data and

I guess Windows is good at compatibility and defaulting to 8bpc is safe.
But unless we have a GUI that allows users to then select 10bpc,
defaulting to 8bpc is not something we should do.

Yeah the world is full of subtle connection problems. In this particular
case, dropping back to 8bps would fix it. But I'm not sure how we would
detect that, or if it's even the right thing to do in most cases.

Thanks that does seem to be an old EDID v1.3 with no defined bit depth.
But there are some vendor-specific blocks there that do advertise
support for 10bpc and 12bpc.
In this case I think it's correct to try and default to 10bpc or 12bpc.
It's probably only the cable or dongle letting it down. I
I found that `find /sys | grep edid$ | xargs file -i` will always report
the file is empty.
Please use `find /sys | grep edid$ | xargs cat` to find out which one is
non-empty and attach the EDID here.

I forgot a display signal doesn't include any alpha channel, so yeah 8
bpc will require less bandwidth than 10 bpc.
The maximum capability of the monitor should be advertised in its EDID.
At least modern monitors do. You can check it using the 'edid-decode'
command and grepping for 'bits per
