TeamViewer Black Screen

VPN
1

Has anyone noticed more black screens when connecting to remote computers? I have the full paid license of TeamViewer and manage many computers. I occasionally will have trouble seeing the screen, it connects and the mouse moves but the screen is black. Usually a reboot on the remote side fixes it. But over the last 2-3 days, I have had this issue with more than 1/2 the computers I have tried to connect to. Wondering if a recent update broke things or something else is happening?

In my experience, black screens are almost always caused by funky-ness at the remote side.

Laptop with the lid closed, PC with the screen off etc.

TV is just grabbing a video stream from the display buffer at the remote side. I have found a few ways to “fix” these issues though.

  1. In a TV session, under “view”, on the right there is a “refresh” button. It seems to pull the remote GPU out of low power states, but you may get some residual funk (like a teeny-tiny start menu for some reason)

  2. Start a VPN connection through TV then RDP over it. This turns on the RDP Virtual Display Adaptor and TeamViewer starts capturing that. Or just use RDP.
    Note: don’t minimise the RDP session or it stops generating an output.

  3. Dummy plugs - but these cost money and come up as duplicate screens.

  4. IDD - basically a software version of a dummy plug.

Many other remote desktop apps (splashtop, parsec, etc) have their own virtual display adaptor. I mentioned this the last time I spoke with support and they said that they are “working on it” - but no ETA.

Hope this helps.

Sometimes toggling hide/show wallpaper fixes it for me

Since it is newest thread regarding this issue, Hope below workarounds might help

  1. On the Windows tray menu, right-click the TeamViewer icon and select Options ➜ Remote Control ➜ on the field Display, uncheck the option Remove remote wallpaper ➜ click OK to save.
  2. Sometimes during a TV session, under “view,” toggling hide/show wallpaper might fix
  3. Lastly, if above workarounds don’t work, then right-click on desktop, click Personalize, then on Background from drop-down menu, select Windows spotlight or Slideshow as you like
  4. Restart the remote computer
  5. Try again, TeamViewer remote session; it shouldn’t remove now remote computer wallpaper
