The former LG TV must had been doing some HDMI wake up or something when<br>
switching from TV to HDMI input. Or kept all outputs under power/active in<br>
all times where is with today's power saving TV's this is not the case. I<br>
guess it's just a bad combination of ATI driver and TV, the driver fails<br>
waking up the HDMI and the TV not helping about this at all.<br>

It's a defective TV and it's not power saving that is causing it. The EDID<br>
circuitry should be powered by the device connecting to the TV so that it works<br>
when the TV is off. There are power wires in VGA, DVI and HDMI specifically for<br>
this. The circuitry is very simple, basically just a tiny EPROM. I would guess<br>
that the TV manufacturer has decided to cut costs by only having one and<br>
connecting it up to the active input rather than have one per input or doing<br>
something smarter. FYI my Sony Bravia does the right thing on HDMI and VGA inputs.<br>

...which might imply that one solution could be to try with your mythtv connected to each HDMI input in turn. I have a Hitachi TV with two HDMI inputs and they are definitely different in operation depending on what's connected where. In my case, HDMI2 is the only one with an "exact-PC" scale option.<span class="HOEnZb"><font color="#888888"><br>
