Dual Monitor

Well as I'm posting the same again just in the other forum, so I'll just quote a problem.

Hello everyone,

I was having a problem with dual monitor using 7127 build. But only when I use newest NVIDIA drivers. My tv just flashes a few times, and I can see that fish a couple of times, but then it just goes to like no signal. If I use default drivers which are installed on windows install, then it works fine, but then I dont have NVIDIA control panel and some other features.
My video card is GF 8800GTS 650M 512MB DDR3 DUAL DVI TV PCIE. I would like to know if anyone else is having this problem and If it has been fixed in the newest build, so I could be arsed to do a clean install

Thanks,

And thanks again

I am running an 8800GTS Dual monitor with no problems. I am not connected via s-video though. I know that nvidia is having some serious issues with their driver (185) and windows 7. I recently had to remove my 8800GTX due to the issue.

On a side note, I sometimes have issues with my 2nd monitor turning on so I have to hit ctr.alt.del to get it to recognize it. Have you tried making the TV the main monitor? Can you see the TV in the display list? Will the TV come on if its the main? Have you checked the cable that you are using connected to the TV?

I would probably wait for nVidia to release new drivers if the cable is not the issue.


Thanks,
JV

Yes, TV appears in both control panels, everything shows like it's working perfectly. I've tried making TV as my main monitor too. I've also tried replugging cables, restarting pc/reinstalling drivers, then plugging in again etc. Nothing helps, it just flashes couple of times, like 2-4, during the flashes I can see the desktop, and then it goes to 'no signal'.

And yeah I'm using the s-video, but problem isnt there I'm sure, it works perfectly with the drivers installed during the windows installation.

Sorry for double post, but I've just tried to install beta 186 NVIDIA Drivers. Well dual monitor works now just great, but there's no NVIDIA Control Panel, I just can't find it..:sarc: Is there something I should know ? Or is it a known bug ?

Edit: I've just tried to do some testing. I've uninstalled the drivers, then installed nvidia display drivers from the windows update, because this is the only way to make NVDIA CP to appear so far, and then installed those beta 186 drivers, now there is the NVIDIA Control Panel option, but when I try to launch it it says ''Version mismatch. Reinstalling display drivers may solve this problem.''.

I have the same issue with my Intel GFX, if i install the drivers from Intel i get the Mobild GFX control panel, but as soon as i download the WDDM1.0 driver from Windows Update, the control panel is gone.

As far as i know there is no way to restore it. Did you download the 186 driver direct from nVidia?

Yes. Well as my card is from XFX I should use XFX drivers, but with those it's the same, and I dont think XFX has 186 beta drivers.

Conclusion would probably be that its a beta version and they didn't include the control panel. Wait for the official release and I bet it will be in there.

Well there's no CP in 185 either, nor XFX 185 drivers.

Try this, right click on the DESKTOP and select PERSONALIZE then click on DISPLAY (Bottom left). Click on CHANGE DISPLAY SETTINGS and select ADVANCED SETTINGS.

The tab to the right should name your video card, select it and see if you see START NVIDIA CONTROL PANEL.

Tried that also, says the same thing ''Version mismatch''.

Edit: I've tried to do a clean driver(186) install now, went to Advanced Settings and there's no more section with the name of the card now at all.

Give this a shot bud, (at your own risk)



If you have tried nearly anything to get the panel back, but with no results, then try these steps below:

Step 1: Make sure you install nVIDIA 185.xx driver (latest preferred). Install by any means so the driver worked. (nVIDIA control panel of course couldn't be launched because of some version mismatch/dll error/hanging explorer or whatever (otherwise you wouldn't read this post)).

Step 2: Download an application called "Universal Extractor". It's a freeware and can be found at softpedia.org. Install it.

Step 3: Go to "C:\NVIDIA\WinVista\185.85\IS\Display\". There must be an exe file called "NvCplSetupInt.exe". If you installed Universal extractor with shell integration, just press the right mouse and extract it to subdir with universal extractor (otherwise use the start menu). Universal Extractor will provide several extraction methods - try any of them till the job is done successfuly. P.S>The Universal Extractor might be needed to run as Administrator.

Step 4: Go to the extracted directory and once again using universal extractor extract the "NVIDIA Control Panel.msi" to a new subdir.

Step 5: Depending on the used extraction method the subdir's folder layout might vary, but there must be single directory containing *.dll, *.exe, *.cpl and *.xml files. Check their presence and reboot into safe-mode.

Step 6: Once in safe-mode navigate to the folder containing those dll/exe/cpl/xml files. Copy all of them and paste them into "C:\Windows\System32\" replacing any same files.

Step 7: Reboot normally and go to windows control panel and check if nVIDIA panel works. It should work (if it doesn't - a) you did something wrong, b) this method won't work for you). If it works - well done! But we're still not done. The driver must be initiallized at startup correctly so that the display brightness/gamma/color and other settings were loaded at startup.

Step 8: make a text file and paste in this:[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Run]
"NvCplDaemon"="RUNDLL32.EXE C:\\Windows\\system32\\NvCpl.dll,NvStartup"
"NvMediaCenter"="RUNDLL32.EXE C:\\Windows\\system32\\NvMcTray.dll,NvTaskbarInit" . Chenge extension to *.reg and add these keys to registry.

Step 9: Now reboot. No errors should occur and the driver must load correctly including autoloading display profiles.

Thanks for the idea tho. I've just tried it and Universal Extractor gave me this error ''Line -1: Error: Unable to execute the external program. The requested operation requires elevation.''. I've tried to extract the exe with all three options, the first said it cant be extracted because exe is InstallShield installer, the second gave that error and the last did nothing at all.

Run as administrator.

I've just did everything you said and everything works just perfectly. Just had to add ''Windows Registry Editor Version 5.00'' line to the top of the reg file for Windows to be able to recognize the file as registry file... Many thanks from me

Awesome, I am glad it worked. Hopefully everyone else with the Control Panel missing from nVidia can use this workaround.
