[mythtv-users] No Display

[Ian Latter]

Hello,


  You've gone further than I have in debugging - I have just
converted my AV/Stereo setup to HDMI too, but the HDMI
Amp that I bought last year won't forward the picture to the
set, so I've just skipped that until my patience returns ;-)

  Is it possible that the TV/Display is only configured to show
a picture when it has audio?  I suspect this is/was the
problem with my Amp (I only just bought and configured an
nVidia GT220 (216) so that I have both picture and audio
in the same cable - two days ago).

  My old 4:3 set used to display a blue screen when it 
detected no signal - maybe your TV is doing a modern 
equivalent ... Try exploring the TV's config options ..

  Actually one other thought .. my set had 4 x HDMI inputs,
and one was specifically flagged as a PC HDMI interface ..
maybe you've just seen why that's important?  I haven't
tried one of the other HDMI ports ...



Good luck,

 It was.  I tried "Play music" and lo and behold, I had
sound and picture.  It worked like normal.  But when I
exited back to the mythtv menu, I got the "No Signal" message.
