I have a Motile M141 laptop running Fedora 32 with KDE and completely
up-to-date on all software according to DNF. I'm really very happy
with the laptop. It's fast, light-weight, and capable. The built-in
screen runs at 1920 x 1080.
When I attach a TV using an HDMI cable, the laptop screen goes dark
and the TV screen lights up. I get the same effect if the TV is
attached before the laptop boots. The TV runs at a lower resolution
but the picture adjusts properly. But there doesn't seem to be any
way to get both screens to light up concurrently, either as a mirror
or extension.
Running KDE systemsettings while the TV is connected and viewing the
output on the TV, systemsettings reports two displays but only shows
one movable outline. The resolutions are reported differently for
the two with the laptop screen resolution showing as 1920 x 1080. But
nothing I've tried seems to make the laptop screen light up. Except
disconnecting the HDMI cable which, of course, makes the TV go dark.
Getting both screens working is my primary interest here and I'd
appreciate any suggestions. But if and when that is resolved, I'll
face the issue of overscan on the TV. To save time later, I'll ask
now: Is there a way to shrink the TV display so that the edges are
all visible?
