SOLUTION for Black Screen Flash After Windows Loads

I was scared that it might be a dying screen, glad I saw this!

 

I didn´t know I had this problem until I found this thread...

Thanks a lot!

 

It's not a "problem" per se, it's more of an annoyance. But be aware that if you use an external projector or second monitor, fixing the annoyance will disable two things.

The automatic detection of the monitor or projector is one.

The other is if you use either in "multi-monitor" mode, where you have different things on both displays, the default operation of Vista is to automatically move things back to the primary desktop for you when you disconnect the second monitor (or projector). If you fix the annoyance, this automatic action goes away. Let's say you have Word open on the second monitor and disconnect the monitor. Word will be "orphaned" with no way to get it back to your main display, until you reconnect the second monitor and drag it back. With some apps if you close them and do not move them back to the primary monitor, the next time you open the app it will be "orphaned" since it opens on the second monitor even though it is not attached.

If you never use a projector or second monitor, none of this matters.

Something I did previously - but not this time (recent reinstal) was move the task responsible for the black monitor to the boot up phase.
That means it flashes black when the screen is black anyways - that should keep it running.

Gary - do you know anything more about it? Would that be a better solution, or not?

 

What a cool idea! I never though of it, and don't remember your sharing the idea before. I do think it is a MUCH better solution, provided it maintains the functionality I mentioned earlier to efrain_lopez.

Can you give the specifics of how you moved the task? I will try it right away as I have a second monitor right here on my desk and can make sure it works. I never disabled the task because the blanking never bothered me in the first place.

I actually hadn't suggested it before...

Basically:
Open the task sheduler, navigate to the task.

Double click the task to get a little pop up window.
One of the tabs is called "trigger" in German - possibly the same in English.

Double click the trigger and you get another pop up.
This one offers a drop don menu where you can select when you'd like the task to start.
The default is "at log in".
In German its "Beim Start" - so in English it sould be called "at startup" - then it loads before the Windows Vista logo, but after the status bar.

Hope its understandable

Edit: I don't know about functionality - it should still be there - but I don't have a projector or second monitor at home to test it.

 

It was. I do. And I did!

Your instructions were quite clear. I do have a second monitor on my desk that I use for development work. I tried your idea and all of the functionality is there!!!! It recognized when I plugged in the display and automatically moved the apps OFF the scond display when I disconnected it. No orphans.

Very nice! Thanks and +rep for you!

Thank you

 

I'd like to open up this discussion again for Windows 7/Windows Server 2008

I could not find a "MobilePC" task listed in the branch under Windows. Has this setting been renamed, removed or changed for Windows 7 or Windows Server 2008?

Here's how to fix that annoying black flicker on boot:

1. Click on the Start button (pearl? ball? orb?).
2. Type "Task Scheduler" and hit Enter.
3. On the left-hand side, click "Task Scheduler Local" (you should already be there, but just in case).
4. Expand "Task Scheduler Library," then "Microsoft," then "Windows," then click "MobilePC."
5. Up top, you'll see a task called "TMM." Click it, and on the right-hand side, click "Disable."
6. You're done. ​

 

It's not an issue in Windows 7 anymore...

 

If it's not an issue then why is my screen flickering after waking from Sleep mode in Windows Server 2008 R2?

I noticed that HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\TMM is listed in the Registry.

 

Maybe because Windows Server 2008 is not Win7? Sorry, I couldn't resist. The TMM schduled task was what was causing the flash and it does not exist in Win7. If you don't see that as a schdeuled task, I am not sure what the cause of your screen flash migh be. Just because you see TMM in the registry doesn't mean it is be invoked.

Gary

 

I noticed that too! And my wireless reconnects instantly as well instead of the old connect-disconnect-reconnect cycle we had before with this.

Gary

 

Windows 2008 isn't the same as Windows 7? Well, it seems similar enough as far as screen flickers go.
It seems several others are having similar problems with screen flickers after updating to Windows 7. If anyone has information on a fix, I look forward to reading it. Thanks.

 

It went away after my upgrade to Win7. That's pretty much all I can offer. Thes TMM task still is scheduled undr Mobile PC, but the flash is gone.

Gary

 

The whole networking system has been so much improved in win7.. god that connect dialog was slow in vista

 

I would just like to point out that this solution was contributed by NinjaNoodles to Les' Vista Tips and Tweaks thread a long time ago.

 

Not only that but NN originated this very thread. (Click back to the first message.)

Haven't seen any messages from NinjaNoodels in a long time though. The last one was over a year ago.

Gary

 

agreed. I'm getting the flickers on win7. I only get it with my laptop set to speed mode (discrete graphics on). Any ideas?

 

I have Mobile Pc, but no TMM just "hotstart" which is set to trigger at log on of a user..could this be it renamed?
