Error connecting to TeamViewer – black screen

Black screen in TeamViewer is one of the most common problems that users face. In most cases, it occurs directly at the time of a remote session, that is, when connected to a partner’s computer. Fortunately, it is almost always possible to solve the problem by improvised methods.

Types of the problem

First of all, it is important to determine what type of black screen you are seeing. The two most common cases are:

  • all shortcuts are in place, and the usual desktop wallpaper is replaced by just a black screen;
  • a black background takes up all the space, and shortcuts and other desktop elements are not displayed.

Both types of problems can often be fixed on your own without leaving your computer.

Possible reasons

In the first case, there is no need to worry.

Disabling the background image is done by the program itself. In this way, TeamViewer improves computer performance and overall session stability when connected to a user’s desktop.

All other PC functions should work normally. If this does not happen, you should pay attention to the causes of the problem from the second paragraph.

The case when a black screen appears without shortcuts and the taskbar is not so common. Such symptoms appear due to incorrect settings of the program itself or occur when there is a conflict with the remote device to which the connection is being made. Less commonly, a similar problem occurs due to incorrectly installed video card drivers.

How to resolve the error

The automatic disabling of the desktop image can be configured in the TeamViewer menu. To do this:

  • open the menu,
  • go to Extras – Options,
  • proceed to the Remote control tab,
  • untick the select the “Remove remote wallpaper” box.

If the problem persists, a step-by-step diagnostic should be carried out on the remote PC according to the instructions below:

Make sure that the partner’s computer has not gone into sleep mode and has a stable network connection. This happens when the PC, just idle, stood for a while.

  • Check connection permissions. To do this, go back to the options, to the “Security” tab. Find the line “Rules for connections to this computer” and set the option “Allowed for all users.”
  • Set authentication method via Windows. To do this, at the time of connecting to the user, open the “Advanced” item (located in the password entry window) and select the “Windows” item in the “Authentication” form.
  • Reinstall the program and / or drivers on the video card, as well as check the settings for automatic login. It is worth working with video drivers only as a last resort and only when there are specific suspicions about this.

The proposed methods are very likely to help eliminate the appearance of a black screen at the time of connecting to a remote computer. If this does not happen, it is recommended to contact the TeamViewer support service and get professional advice from specialists. It is also recommended to study the thematic forums in which you can stumble upon a mention of a similar situation.
