TeamViewer 12 and black remote screen not working

Question

I've been looking for a solution to this, but I cannot seem to find anyone who has solved it (or even have the exact same problem).

My problem is that "Show black screen" option when connecting to a client doesn't work. "Disable remote imput" works, though. But the remote screen simply doesn't go blank.

I tried enabling the "Enable black screen option in the settings on the teamviewer "server", but when I did that the client couldn't even connect - it got stuck on "Initializing display parameters" forever.

Since I'm trying the free version of TW before buying, there also is absolutey no help to get from the TW team.

Anyone got any suggestions?

I've installed and reinstalled the TW monitor drivers on both the local and the remote computer, but it doesn't even seem to ATTEMPT to black the remote screen.

UPDATE: When connecting from Computer1 to Computer2, it doesn't work (as described above). However, when connecting from Computer2 to Computer1, it works.

So the problem seems to be with TW and the display drivers on Computer1.

Solution 1

No one has an answer to this. This is no wonder, since TeamViewer themselves has verified this as a known issue/bug. With no scheduled fix, of course.

The problem is with the NVIDIA drivers. Some further research seems to suggest that the problem occurs in the latest handfull of versions. I've not got the details of that, and I don't find it very relevant as TW doesn't seem to prioritize the issue.

Solution 2

I have it finally working on my computer. The issue is pretty simple and a complete embarrassment or lack of technical skills on TeamViewer's point. The driver is not "digitally signed" with a correct date so Windows rejects it. If you go into your BIOS and allow drivers once to be approved without signature then the TeamViewer black screen works correctly. Just search in google for

"Windows cannot verify the digital signature for this file" error

There are plenty of links on how to fix this and you don't have to make it permanently accept all unverified digital signatures. Just this accept it this once.

Again this 100% TeamViewers lack of professionalism by having a simple low level driver not digitally signed and approved. Hope this helps

Here are the details of the NVidia driver issue.
NVidia driver version and will black screen work...
368.69 - OK
375.70 - OK
376.09 - OK
378.92 - OK (3-20-17)
--------------------------------- Breaks here
381.65 - NO (4-06-17)
381.89 - NO

As of 5/10/2018 - (over 1 year!) The issue is still not fixed.

I got it by mail from their support team. There's also a thread about it in their support forums.

This one?

Yup. That's the one where I answer my own question, referring to the answer I got from TW.
