A while back my Intel NUC failed, and I replaced it with a newer one.
Since then I have been having a few issues with my display.
The first is overscan - the NUC is used as a media PC, and is hooked
up via an A/V receiver to a HDTV using HDMI. Unfortunately there
doesn't seem to be a way to tell the TV to turn off the overscan.
With the older NUC, I used intel_panel_fitter (I think) to adjust the
display, and all was well. But that program doesn't work on the new
NUC. I can however, use xrandr's transform settings, and this seems
to be OK. If anyone has better ideas for accommodating overscan
(other than buying a new TV), I would love to hear it!
The second issue is that when I switch the TV away from the NUC, and
then eventually back to the NUC, the display is zoomed slightly - just
enough so that the KDE bar at the bottom is now off-screen. I can use
xrandr to reset the transforms to their default, and then re-apply my
desired transforms and it is back to where it should be. But I would
like to eliminate this annoying "zoom" altogether if possible. I
thought maybe treating it similar to a KVM switch, and forcing the
modeline within the xorg config would help, but it doesn't seem to
change the behavior at all.
The third issue is that sometimes I lose the display more-or-less
completely. I switch the receiver to the NUC, and I get a black
screen. If I reboot (via a ssh session), I get nothing. To get the
display back, I have to poweroff and cold boot. The login screen is
fine, but after logging-in, KDE seems to be set for a lower resolution
(800x600?) than the TV is using (1080i), and I have go into "System
Settings" to correct it - which is difficult when you can't really
read the display very well!
Any suggestions on these issues would be appreciated! My google
searches haven't come up with much help.
