I have a fresh install of MythDora 10.21 that works fine with my Dell 15" monitor but when I try to use it with my Magnavox 37" flat panel TV I get nothing, no signal to the TV.
when I configure my nvidia display settings it sees the TV and I can make the config changes and save it but still no luck.
I have another Mythbuntu box I use that is connected via HDMI that works fine. this is the version of xorg:
X.Org X Server 1.5.3
Release Date: 5 November 2008
X Protocol Version 11, Revision 0
Build Operating System: Linux 2.6.18-92.1.18.el5 x86_64
Current Operating System: Linux localhost.localdomain 2.6.27.15-170.2.24.fc10.x86_64 #1 SMP Wed Feb 11 23:14:31 EST 2009 x86_64
Build Date: 11 December 2008 05:27:30PM
Build ID: xorg-x11-server 1.5.3-6.fc10

Any help would be greatly appreciated. Here is a copy of my xorg.conf file if it helps.

I'm an idiot, your right it didn't see it because their is a jumper setting on the xfx nvidia geforce mobo that enables HDMI, I had it on the DVI. Here is a link to a pic of the mobo and jumper.

It works fine now. I had to not let nvidia settings force scaling but let my tv do it and the picture looks and fits great on my 37" with the resolution set to 1024x768.

Same issue I had and resolved by moving the jumper (a row of 8 pair of jumpers). However, my Sharp LCDTV can sync correctly to 1920x1080, but my Dell monitor cannot (with it's HDMI connection). Anyone knows why this is happening? An LCDTV can sync correctly, but a Dell monitor cannot?
