Given that several Linux distros identify (on boot) my display brand

identify just what package, module, or kernel part this "bug" hides
in?
I'm using a Sharp 32" LCD tv via hdmi cable, and it's identified as a 37".
That's not as important as the default resolution, which comes up as
1280x720, but should be 1360x768 (or 1024x768 if wxga isn't doable).
When I had a similar problem a few years ago, I was given a magic
spell that worked for me. Create a file, /etc/X11/xorg.conf, a put
the following in it:
Section "Device"
Identifier "Configured Video Device"
Option "UseBIOS" "off"
EndSection
This disables a section of the "BIOS" of the video display
monitor. (NOT the 'BIOS' of the computer) . Some manufactures
seem to have seem to have recorded operating parameters for
a CRT monitor into their flatscreen displays. Or some such
craziness. As I say, except for the crazy explanation, this
is purely a magic incantation that has worked for me.
YMMV, HTH, etc..etc.
See man xorg.conf for a more impressive explanation.
