Thanks - I tried your recommendations, however - now, it sets the
resolution to 1024x768, however the TV displays simply a blue screen -
'No signal'
I've tried to trim and paste the relevant parts of the Xorg.0.log file
here. It looks to be like its validating the 1440x900 resolution, but
it falls back to 1025x768 which gives me 'blue screen' :( My Xorg.conf
file is pasted below too.
Any ideas?I don't understand why mythbuntu driver can display 1440x900
but NVIDIA can't ?

Looks like it sets 1440x900 - but a few lines later it sets 1024x768?
