Default FX5200 DVI -> Sony HDMI Signal Issue?

Hi all,

I've recently bought a shiny new Sony Bravia KDL32W5500 that I am using with MythTV 0.21 on CentOS 5. The visuals work fine, pretty much out of the box, however I have a small but annoying issue with the PC/TV. The FX5200 is connected to the TV with a DVI to HDMI cable and I am using the NVidia drivers 173.14.20.

If I boot the PC with the TV turned on everything initialises correctly. If I turn the TV off and then back on again, I just get a black screen as though the TV has no signal. If I log in remotely and restart X I still get a black screen. In fact, the only ways that I can get the TV to show the image that the PC is still (presumably) outputting is by:

- Changing the resolution of the X server in xorg.conf and restarting X
- Rebooting the PC with the TV turned on
- Unplugging the DVI/HDMI cable and plugging it back in again

It appears to me that the PC isn't sending "something" to the TV that it needs in order to recognise that a signal is present despite the fact I can see the picture! Another side effect that I've noticed is that occasionally the TV reports that it is about to go to sleep, again presumably because it doesn't think that it is receiving a signal.

Has anyone come across this before? Any ideas on how I can resolve it? I've spent many hours digging around the 'net and haven't yet found the cause/solution.

I thought it may be related to this: http://www.mythtv.org/wiki/Nvidia-ca..._before_the_TV, but I've tried what is described without any joy. That said; the symptoms I've described don't really match that anyway.

Something like this: http://thydzik.com/hdmion-a-solution...nal-on-hd-tvs/ sounds right ... but I don't know how to do this in X.
