DVI - nvidia problems

Where is a good place to get information on XP/nvidia/DVI/HDTV? I've got a few issues, and the nvidia forum is pretty useless.

I have XP Pro SP2 32 bit, GeForce 8800GTS 320MB, GeForce 8 series driver, dual DVI, one to console display and one to Philips HDTV. I set the nvidia control panel to clone mode, and this works usually, until I set the HDTV to a new channel or turn it off. The nvidia driver/firmware whatever then shuts down the secondary DVI output, so if I go back to the DVI input on the HDTV there is no signal. The DVI line drop doesn't occur right away, takes about 5 min. or so. I want to lock the nvidia settings to clone mode forever; the computer is in a different room, there is an annoying bit of walking back and forth sometimes. The nvidia drivers are pretty variable from one release to the next and none has solved this problem. At least one of their releases won't detect the Philips tv at all.

AVS forum has a pretty good HTPC section.

Have you tried running drivercleaner before reinstalling the newest drivers?

There may not be a satisfactory answer to your setup problems.
I would email nVidia directly, and start there.

This is done to save power.

One trick would be to use some active HDMI accessory to load down the HDMI
output, even when the TV was turned off. I suspect that a HDMI splitter
(they are about $30 on eBay) would do this for you.

You are the first person to have any idea. Sounds reasonable. Just to be clear, do you think it's the video card that is trying to save power?

Very interesting idea, and again no one has suggested this before.

The overall idea is that I can run a beyondtv feed on one hdmi input, but be able to use the built-in tuner to watch something else. That, plus not have to set it up every time I turn on the set.

"You are the first person to have any idea."

I did your searches for you. (in: alt.comp.periphs.videocards.nvidia,
and the nvidia forum..... and the AVS HTPC forum)

Your problem has little (directly) to do with saving power, although they
say it may be triggered by some power-saving scheme on your PC.

I found the specific problem is that your videocard is losing your display's
"EDID" info ["Extended Display Identification Data"].

I read that ATI cards have handled the EDID issue much easier than the
nvidias, so I'd consider switching it out.

In-depth Nvidia/EDID exploration he http://www.geocities.com/jgeneedid/
The bottom line seems to be:
a.. "Contact your display device manufacturer and obtain an updated firmware
that addresses the EDID problems
a.. Wait for the device drivers from nVIDIA that can address EDID-related
issues
a.. Overwrite the EDID on your display device and or use a hardware device
(see below) to work around the issue caused by the faulty EDID "

a.. ++++++++++++++++++++++++++++++++++++++++++++++++++ ++++++++

As another hardware device work-around [made specifically for EDID issues],
here's a $70 Gefen "DVI Detective".
Gefen sez:
"Once installed and connected, the DVI Detective continually transmits the
EDID to the computer, essentially "tricking" the computer into thinking that
the video is present, even when it is not connected."

Excellent, I didn't even know what to search on. EVGA support, nvidia forums, etc. never said anything about this.

Loss of signal appears to be solved with the nvidia 175.16 driver and the latest tv software from Philips.

Glad you didn't have to add the black box. Kudos. :-)
