Viber Windows 10 Not Working

[Elnora Heidrick]

Myproblem is that some programs (Handbrake, NordVPN for example) only comes up with a white window when launching them. You can see the Title on top of the window and you have the "X" to the top right to close the program, but that's it.

Funny thing is that when I launch the program in front of the host and then later connect remotely the program does display everything correctly. Same thing if I reboot the computer and launch the program remotely.

Not sure what just happened, it was working just fine and suddenly applications just start showing completely white?? Just like that. No changes of drivers, applications, configuration, absolute nothing different than an hour ago... and bam, Teamviewer completely useless. How is that possible?

I think someone must have shut down the display/monitor connected to it by accident. It has a DVI input but dunno for sure what type of monitor is connected. Probably a cheap screen though since it's mostly used remotely. Thanks for getting back to me so quickly. I guess i'll stop trying to troubleshoot that remotely. I've reinstalled drivers, applications, installed chrome remote deskptop to try an other remote desktop application, same **bleep**. It's too frustrating, i'll wait a few hours until someone's physically in that room and turns the darn monitor on again. SMH.

Cheers.

Typically, monitors or notebooks display shall report their data (such as what resolution they support) to the graphic card once they are connected.

The monitor itself does not need any power, as the HDMI / DVI / VGA cable itself provides enough power.

Unfortunately, there are some monitors that will only pass their data to the graphic card when they are turned on/have power.

In this case, the graphic driver shall decide what it wants to do when the monitor is not detected. There have been 3 cases detected thus far:

TeamViewer grabs the screen as it is currently displayed.

In other words, if Windows did not draw anything, TeamViewer cannot grab the screen, so you will only see a black screen. Unfortunately, we cannot do anything against that.

Hi,

Do you use an integrated graphics chip or are you using stand-alone? --> I use a GTX1080Ti with the newest driver.

Does this only happen on Teamveiwer? --> It only happend with Teamviewer. At the PC the software works without any problems. I did not use any other remote viewing software.

Have you installed the Monitor Driver for the software, if so was that successful? --> No, how to install a monitor driver for a specific software, this is new to me.

Yeah, I got this problem now that I've installed SAMSUNG U28E590D 4K monitor, connected by DP cable, Firefox would whitescreen, I was able to fix this by disabling graphic acceleration but Windows Live Mail still only displays part of the screen, I may have to unplug the cable when I get home to see if it resolves this as I've been at this all night remotely, getting nothing done, I never thought switching a monitor would be such a pain. :-/

I've since found that connecting a HDMI cable to the mb port to monitor seems to fix this, I can still default to using the add on video card to monitor by DP cable when at home but somehow having that second connection resolved this issue.

When using teamviewer to remotely view other computer equipment (a WorkStation) I can not visualize the 3D screens (which have movement and allow you to model and visualize some data in 3D), this did not happen previously, but since I upgraded to the latest version it is not possible for me Visualize these data in 3d dimensions. Has something similar happened to you? How can I configure Teamviewer so that I can visualize those windows as I could before? Thanks in advance.

For me, I get black windows! I am remoting into a laptop media server, which used to work fine. However, as of a couple of days ago, I am starting to see black windows for VLC (I hear audio but see no video), Next PVR, and even Firefox and Edge browsers. It's the same whether I use TeamViewer or **bleep**. However, following the comments above, I have just realized that if I open the laptop lid, all the windows display correctly. If I close it again, they go black. So, yes, it's definitely a rendering issue. I wonder if there was something contained in a recent Microsoft update that caused this behavior?

Hey I have exactly the same problem and a Samsung monitor. When you say 'connecting a HDMI cable to the mb port to monitor' ... what do you mean by mb port to monitor? Just trying to resolve this issue so I can actually use TeamViewer? Thanks

This sounds like my exact issue, but the remote machine is a Mac.

The remote machine is mac mini that does not have a monitor attached at all. It is headless.

The issue only started after upgrading the remote host to Mac OS Mojave.

I have used Team Viewer without issues on this host for around 6-12 months, without a monitor attached.

Please note, **Third Party Product** is working perfectly fine and it's the only reason I can continue to work remotely on this machine.

With an external monitor plugged into the mac mini, the problem is solved. You can then unplug the monitor and the remote session continues to work.

After a reboot, the problem returns, unless a physical monitor is present.

I'm going to try the dummyplug, that could be a cheap solution. They are under $10 online.

When I open Internet Explorer Edge remotely with Teamviewer (latest release), it shows the start page fine. However if I go to any other page it shows a blank. If I grab on the edge of the window and drag it to make it larger, the page goes from blank to displaying the content, but only while dragging. As soon as I release my finger from the mouse button, the page goes blank again, How to fix this?

I found a workaround: I've installed the VPN driver on my client and on the TV host, and selected VPN when connected to the TV host and using the VPN tunnel I was able to create an RDP connection from my computer to the TV host and this connection can run and RDP client properly.

Hi. Same issue here. This is not a fix, but i found with my monitor that instead of I shut it down from power button, I change picture source to something else than DP, which i normally use. My monitor goes black since it has no signal and after a while it goes sleeping. With this i can sleep my nights and remote desktops work fine. (Teamviewer and google remote) If I shut down from power button neither of those does not work.

The teamviwer team can do something to prevent this form happening ... this software uses a virtual display driver that activates the videocard just like the physical display monitor ... use this software:

The remote desktop protocol is an approach to accessing windows from a remote area without really accessing your device from its actual location. Moreover, the users using the remote desktop protocol can utilize their windows platform anytime and any place they want. The remote desktop protocol is a product from Microsoft Corporation. The protocol came in to deliver the windows server at residence. Using the remote desktop protocol is easy. It is as comfortable as hitting an icon to control your Windows from any other external computer or smart device. The remote desktop control also enables you to share the mouse and keyboard activity with the remote device. Users accessing the remote desktop control can access the Windows/ computer as if they are working on the same computer. It creates an exact ditto environment to work on. The significance of RDP has made it popular among users.

If I do not want to block any applications then what is the point of using application control ("monitor" or "allow") in the "1" rule. What is the difference between "monitor" and "allow"? In both cases, the applications witch runs on HTTP and HTTPS will work. When I use the "monitor" settings then I will have a log entry in Securtity Events/Apllication control logs and when I use "allow" settings then not? That's all? What's the difference between setting application control on a firewall policy with alow and not setting up application control at all?

With the above rules the VIBER windows desktop application sometimes works sometimes not. I tried to add an appication control to the "1" rule with alowing viber, but it still dos not work well (could not send pictures).

Application signatures are useful to identify applications because today so many applications share the same ports, for example as you know 443 was used only by browsers but today is used by thousands applications, so allowing 443 does not make sense anymore.

there is only one Viber application signatur on fortigate and I'm only interested in the desktop app. About the ports: I only found the two pieces of information I wroted (according to Viber and according to Fortigate application control).

Yes, it can be very useful to know what applications are running on ports. You can "block" the categories you don't want and override olny the ones you do or you "allow", "monitor" the categories and "block" in override what you do not want. If you just want to know what's going through, you can turn on "monitor". Using "allow" and "monitor" in override only makes sense if you have blocked a category before. Somehow I thought that with "allow" fortigate would open the extra ports in the session that the application needs (like a helper).
