Clicking on a video file makes monitor go black
I'm getting some really odd behaviour on my editing computer.
Whenever I right click on a video file (avi, mov, wmv, mpeg) on one of my hard drives to play it, the monitor screen goes black for a second and then comes back on. Sometimes, it doesn't go all black but it has a small momentary partial black glitch, but more often it goes totally black for about 1 second. I have no unusual software on this machine. Just video and audio editing related software. No internet or games or firewalls or virus checkers. It's optimized for video editing. The only software that has been installed in a while is the latest Avid Xpress Pro 4.6 upgrade. While trying to check on this problem, I noticed that device manager reported a default monitor and when I tried to reinstall the inf files for the monitor, windows failed to start after I restarted. I tried twice and windows would go black after the xp logo screen after the bios screens. I had to use last known good configuration to get back into windows. I reinstalled the latest drivers for the video card and the monitor inf file and it then worked ok. But all this happened after the original problems and did not make any difference to the problem. It's still going on. It happens all the time, whether I've been running programs or right after a fresh start. I have an MSI 128 mb Nvidia GeForce FX5700 ultra video card and an Iiyama Vision Master Pro 400 17" monitor set at 1024x768 at 32 bit colour and 85 refresh rate and am not using normal default settings in the options of the video card. Windows Xp SP1 is installed with a P4 3 ghz cpu and 2 gig ram. There is Direct X 9c, Media Player 9, and quicktime 6.5 installed on the system with the rest of the editing software. Can anyone please offer some advice on what may be going on here? Thanks a lot for any advice. |

I tried twice and windows would go black after the xp logo screen after the bios screens. That's probably because it was running at too fast a refresh rate for your monitor. You can push f8 at startup and start in vga mode to fix that. Can anyone please offer some advice on what may be going on here? All I can suggest is reinstalling directX Michael |

This causes the first flicker and unfortunately the auto-startup-entry can't be deleted. The flicker when right-clicking on video-files is caused by a shell- extension, which the nvidia-driver installs for all types of video- files. This shell-extension calls nvcpl.dll everytime you right click a video file to scan for connected TVs. If a TV is present, the shell extension shows up in the context-menu as "Play on My TV". I never tested this, but I suppose when you click it, the video is directly shown on your connected TV. This could have been implemented a lot better, this f...ing sync-flicker is driving you crazy when browsing a video archive. After scanning the registry, I found the key responsible for the shell extension. Just search for "PlayOnMyTV" in the registry and you will find some entries under "shellex" (shell extension). These entries contain an identifier, {FFB699E0-306A-11d3-8BD1-00104B6F7516} in my case, I'm not sure if this identifier is static or created dynamically, so in your registry, it might be another number. Now copy the identifier and search for it in the registry; delete every occurence when it's connected to video-file formats (.avi, .mpg, .mpeg and so on) and afterwards the "PlayOnMyTV"-shellextensions."

Sometimes, it doesn't go all black but it has a small momentary partial black glitch, but more often it goes totally black for about 1 second. could be a nVidia driver problem with nvcpl.dll REPOST from someone not so long ago: my monitor displays goes black (as though the video signal has stopped) randomly for a few seconds and then comes back. Occasionally it is long enough for the monitor to go into standby mode so fairly certain the signal is ceasing. In fact, I've already disabled nvcpl.dll a long time ago, because it was causing unstability under Win98SE (ISTR) running Nero. I took the opportunity to clean also other non desired programs. [HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Curr entVersion\Run-] [...] "OWCCardbusTray"="ocbtray.exe" "WinFast Schedule"="E:\\My_Programs\\Multimedia\\WinFast WFTVFM\\WFWIZ.exe" "WinFoxV2"="E:\\WIN98\\SYSTEM\\WF2K.EXE" "WinFast2KLoadDefault"="rundll32.exe wf2kcpl.dll,DllLoadDefaultSettings" "NvCplDaemon"="RUNDLL32.EXE E:\\WIN98\\SYSTEM\\\\NVCpl.dll,NvStartup" "nwiz"="nwiz.exe /install" "nForce Tray Options"="sstray.exe /r" Then I looked for the value you said (PlayOnMyTV). Unfortunately it's not in my Registry. I found two other occurrences of nvcpl.dll : [HKEY_CLASSES_ROOT\CLSID\{67E0E3C0-3068-11D3-8BD1-00104B6F7516}] @="NVIDIA CPL EXTENSION" [HKEY_CLASSES_ROOT\CLSID\{67E0E3C0-3068-11D3-8BD1-00104B6F7516}\InProcServer 32] @="E:\\WIN98\\SYSTEM\\nvcpl.dll" "ThreadingModel"="Apartment" and [HKEY_LOCAL_MACHINE\Software\CLASSES\CLSID\{67E0E3C 0-3068-11D3-8BD1-00104B6F 7516}] @="NVIDIA CPL EXTENSION" [HKEY_LOCAL_MACHINE\Software\CLASSES\CLSID\{67E0E3C 0-3068-11D3-8BD1-00104B6F 7516}\InProcServer32] @="E:\\WIN98\\SYSTEM\\nvcpl.dll" "ThreadingModel"="Apartment" Dunno if this helps the diagnostic. -- Regards, SPAJKY ® & visit my site @ http://www.spajky.vze.com "Tualatin OC-ed / BX-Slot1 / inaudible setup!"

Maybe your computer's power supply is not enough to support high power.

Thanks for the very informative reply.
I also have another nvidia card, a GeForce fx 5200 128 mb on my internet computer which doesn't misbehave at all, yet the computer is a general purpose family computer loaded to the gills with all sorts of crap, plus broadband and firewalls and virus checkers and games. And it has all the same software as the editing computer as well. The cards are from different manufacturers, but the computers are very similar in other respects such as motherboard, cpu, ram and monitor brand. Why do you think that the barebones editing computer monitor would be playing up when I right click on a video file while this other computer is rock solid? Could the problem perhaps be in any way connected to a fault in the monitor itself or something else like a cable? Thanks. "Mac Cool" wrote in message ...

Mac,
I tried your advice and it worked!! Thanks a lot for your help. Let me report, though, that the search on my computers regedit failed to turn up any Play on My TV instances, and there was nothing about shellex at the location you mentioned. But as it happens, my internet computer also has another nvidia card, a 5200, and a search on this computer's registry did turn up several instances within the local machine/software/classes directories under various video file extension names (avu, mpeg, wmv) although not others such as mov and omf. Using this, I was able to find the play on my tv entries on the video computer and after I deleted them, the problem disappeared. But the problem doesn't occur on my internet computer with its nvidia card, so I've left that one alone. They both have the same driver although they are from different manufacturers (the problem card was a 5700 ultra from MSI, the other one I forget but its only a 5200, which is not classed as a performance card by nvidia like the 5700 is. ha ha). Now the only time that I get a screen blackout is when I'm in the display properties window itself and I click on some tabs in the advanced area, mostly monitor and adapter, but also just by going to advanced. I tried to see if these had some similar settings in regedit but I don't know enough to find them. But I use this so rarely that I'm not too concerned. Nothing like this happens on my internet computer and its cheaper nvidia card. Thanks again for your help. "Mac Cool" wrote in message ...

Luis ORTEGA:
Why do you think that the barebones editing computer monitor would be playing up when I right click on a video file while this other computer is rock solid? I don't know. Each time I have had the problem it just started happening. It didn't seem to coincide with a new driver any other change, it just seemed to start out of the blue. Could the problem perhaps be in any way connected to a fault in the monitor itself or something else like a cable? That was my original thought, but changing monitors or cards doesn't solve the problem. Glad to hear it worked for you. -- Mac Cool |
