Hi,<br>
I have had MythTV up and running at 1080p on the older sharp 42" LCD but I<br>
recently moved and purchased a new LC-42D64U since I liked my old unit.<br>
When I first booted up my Myth machine connected to this new TV it seemed<br>
to just lock up. Upon closer inspection I found I was able to boot into<br>
text mode ok, the problem only seemed to happen when the system tried to<br>
start the X server. It seems when X tries to initialize the display it just<br>
locks up. If I try to start X at 1920x1080 I get a black screen on the<br>
display and the system doesn't appear to load X. Control-Alt-Backspace does<br>
not get me back to the prompt - I have to reboot. If I start it at a lower<br>
resolution (say 640x480) I get the same thing on the screen (nothing) but I<br>
CAN use control-alt-backspace to kill X and return to the prompt. Also,<br>
based on the hard disk activity and messages after killing the server, X<br>
appears to load normally at this resolution but the display remains black.<br>
<br>
I read the EDID information from the using monitor-edid (This machine is<br>
running Fedora 7):<br>

The video card is a Geforce 6150, Nvidia driver is version <a href="http://173.14.05." target="_blank">173.14.05.</a> The<br>
monitor is connected via a DVI->HDMI cable. I ran startx -- -verbose 5<br>
-logging 5. The log is too big to post and will make a mess of this<br>
message, but here are the interesting parts that I believe may be the cause<br>
of this problem:<br>
<br>

<br>
Why can't it seem to find the display even when it is plugged in and<br>
operating in text mode? Any thoughts on how to get around this? Has anyone<br>
got Myth working on this TV? If so I'd love to have a look at your<br>
xorg.conf.<br>
<br>
Your help is greatly appreciated.<br>
<br>
Regards,<br>
Erik<br>
