There's really no much point in changing the resolution of the screen
to match the video being played.
To have the TV do the upscaling or Myth ends up being the same ;
except that now your OSD and menus will look crap.

You're much better off keeping the resolution at 1920x1080 and only
changing the refresh rate.

You can configure myth to also change the resolution, but it's rather
limited. You can configure up to 3 different resolutions to switch to
in myth and the setting must match the resolution you've set.

Remove those 2 settings; let myth do the upscaling...
