Just tried 185.18.14...

Overscan situation is unchanged.  Furthermore, Mythfrontend doesn't come
up all the way.  I get the background, but no menu items.  Tried
kill/restart several times, no good.

Back to 180.60.


Hi Dale
Without checking I assume your TV is a SD TV?  (Yet it has HDMI input?)
If so why not use an older (?pre 8xxx series or even earlier) card and use the older driver which has overscan correction abilities?
I'd like to also acknowledge your comments about apportioning blame, there are threads on NVIDIA's site about this and the one I was 
following has yet to enjoy a response from NVIDIA, as best as I can tell it seems unlikely to get one now.
I have not tested beyond NVIDIA cards and your observations are interesting.  It suggests to me the "good" machines do have overscan 
correction built in, and presuming this to be the case it seems another competitive reason for NVIDIA to match what the competition 
do - or risk sales.... It may be that other branded cards may be better for these problematic TV's and will enjoy increased support? 
I've not looked into the overscan corrective abilities of other branded cards, can anyone clarify? Maybe we should have a new thread 
simply called Overscan correction?
