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

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

</div></div></blockquote></div><br>I think the problem now is the VerticleRefresh. 1440x900_60 is not really 60Hz but 59.9Hz. Try changing yoru Vertrefresh to 20.0 - 75.0. You may want to change your HorizSync to 15.0 - 81.0 as well. The nvidia driver and the EDID information should be able to find a refresh rate to work within the specs of your TV.<br>
