Help - DVI signal from PC gets dropped by TV

[ahedberg]

Otto -

I changed the following setting on my tv and then reinstalled the drivers and have not had an issue for three days.

menu > setup > other adjustments > no signal shut off = no.

I still think it is a driver issue and something 'stuck' the last time I installed. I don't know if it will last. Can you see if you have the same setting on your TV?

Now, my remote stopped working .... argh!!!!!!

PS - no love from xfxforce yet.

[Otto]

Hmmm. What if you unplug/plug in the cable?

XFXForce didn't say anything?

[ahedberg]

I can plug and unplug to my hearts content... I rebuilt the machine last week end and the problem did not resurface. Do you have a simular setting?

I stopped trying to work with XFXforce, they didn't have much to say until I tried it on another HDMI TV (which I don't have).

I still think it was a problem with the driver, and the reinstall finally took. We will see if it re-surfaces.

[Otto]

Hmmm. I know my TV has an auto-off feature, but I'm not sure if I can control it. I'll have a look tonight (if I remember). But I think last time I did a fresh XP install, I was using a Dell analog flat panel, and it died as soon as I unplugged and plugged it back in (i.e., there was no TV in the loop such that the auto-off feature wouldn't matter).

I think I'm going to buy the same motherboard you have and just build a new machine. One question about your motherboard -- do you know if it will output analog and digital audio at the same time? I really need that feature!

Thanks.

I had both an auto-off and a no signal shut off, but if you are having issues on a monitor, that blows my theory out of the water.

I don't know if the MB does both analog and digital, I am using a Xplosion card. Is there a quick way to tell? One thing to note is it does not have firewire...

Hey Andy,

Not sure if there's an easy way to tell if it does analog and digital at the same time. I'd only suggest hooking it up and trying, but that can be a pain. Don't worry about it; I just figured that if you knew right off the bat, it would help me make the decision tonight.

Thanks.

Hi Andy,

Is it possible that you have a Logitech wireless keyboard in your system? I bought the same motherboard that you have (Gigabyte GA-P35-DS3L) and I have the same problem with the video card (that motherboard will do analog and digital audio out at the same time, btw). I was reading on the NVidia site, and they said a similar problem could occur if you have a Logitech camera installed, but I don't have one. I am using the Logitech DiNovo keyboard, though, and I'll try removing it from the system tonight.

I can't believe that there is simply no end to this. I have replaced everything except the RAM, the processor and the drive. I believe more and more that this is a video driver problem.

Hi all,

Just come to this thread late, so apologies if I've misunderstood along the way.

Are we saying that if you disconnect the PC Video Card's output and then reconnect it you have now lost the output and/or blue-screened the PC? If so, that's common to most modern video card drivers. It doesn't matter whether the diconnect is done manually (pulling the plug) or electronically (switching over using a switch).

There's no fix other than using the latest drivers (which probably won't be any better) and/or switching off the pc prior to disconnecting the video output.

Modern video card drivers simply don't like to see no monitor connected, and they either lock up or crash when that is the case. You really can't blame the card manufacturers; the cards are designed to be permanently connected to a monitor.

Regards,
Tony

Otto - No logitech here. I have been using a wired keyboard... bought the microsoft verson, but it was junk.

I agree that it is a driver issue... Not to rub it in, but my problem has not resurfaced. As I write this, I am thinking I should take a snapshot of the OS drive when I get home, just in case it resurfaces.

I imagine that you completely reinstalled the OS if you have anew motherboard. When you rebuilt, did you have your PC connected to the Internet? Was the video card in? With Vista, the install will look at the MS Update site and download drivers for the device, which would then be over written when you installed the ones from XFXforce. Maybe there is some legacy from that. When I installed, I have the videocard in, but was not connected to the internet. Beyond that, all I can say is ***!

Andy

[Otto]

Yep, reinstalled the OS multiple times between this motherboard and the last one. Used both XP Pro and MediaCenter. Not sure if I was connected to the Internet or not. I don't have Vista, though, and when I installed XP, it was SP1, and I had to upgrade to SP2. Previously, I used "Driver Cleaner" or something like that, which they (XFXForce) said would remove all drivers. Same problem.

I'm talking with NVidia directly about their drivers since XFXForce just directs me to the NVidia site for driver downloads. Therefore, I think it's NVidia's problem to talk about drivers.

Thanks again.

Hello!
I have the same problem with my TV.
I have an HTPC with ATI X1250 (also tried ATI HD2600pro) and the picture dissapear when i turn off the TV and back on.
The only thing that helps is to unplug HDMI cable and set it back in, or restart the HTPC or last to set the PC in sleep and back on. (I can set the PC in sleep for 0,1 sec and back on for the picture to come back on).
Here in Sweden there are more people who has the same problem, as i can se most of them with ATI Graphic cards.

Hi Kristain, and welcome to the Shack.

I think that's a slightly different problem. I also have an ATI x600 video card, and I'm using it because I have so many problems with the NVidia 7600GS card. The ATI card only sometimes loses sync for me, so it's the much lesser of two evil. Plus, as you say, it will come back if you sleep and wake the system, which (while a pain) is easy to do.

Anyway, I've also been trying to fix that problem. The latest thing I've tried is to allow "clone" mode in the ATI Catalyst Control Center software, but make sure that my primary monitor is in the "Monitor 1" position. I haven't seen a problem with that mode yet (a day or two), so I'm not sure it's the answer. However, it definitely resolved a problem I had in which PowerDVD was displaying a blank picture.

Anyway, good luck. I can't seem to beat this thing myself...
