Attached. The MDF does go up to 1980 x 1080. But that would totally fill
the display here!

Yes. I increased all the bandlimit values by a factor of 10 some time ago.
At present I'm not sure what has been causing the various errors. It may be
the large modes, or something else. I'll experiment again if after various
other changes they cease or become rare. But for now, if it works OK, 1280
x 1024 actually suits me OK as per an old AKF MDF.
Here is the LG1920 MDF that I used along with the ones you sent.
