[mythtv-users] HDMI - no signal

[Mick Sulley]

Update - The card arrived and I installed it, played around a bit and I 
now have a video and audio on the TV via HDMI.

That is the good news, the bad news is that resolution is all over the 
place and I have no idea what to try next!

This is a straight Mythbuntu install with the xfce desktop.  When I boot 
up I see the normal Ubuntu 12.04 on purple screen, there is a small 
black border to that but it looks pretty much as I would expect  When 
MythTV starts (using MythCentre theme) the blue scree is about half the 
width of the monitor and 2/3 the height and it is in the top left 
corner.  If I exit that and drop to the desktop the resolution is so low 
that it is virtually unusable.

I can access it via ssh from another machine, so I can live with the 
desktop issue, but I do need MythTV to use the whole screen.  I guess 
there must be a config setting for this somewhere, any ideas???

Thanks
Mick
