Win10 upgrade 1607 anniversary update official version of the external display part of the background lost solution

Now, Microsoft has released the official version of the Windows 10 1607 anniversary update, but users encountered a lot of problems after the upgrade. For example, one user fed back his own notebook with an external monitor, and the background part was lost after updating the Win10 anniversary update. Depending on the situation, the external display may have a 4/1~3/1 partial background display that will be pure black, and the mouse cursor will still display properly. What is going on here?

There are some indications that the following scenarios may trigger this issue:

1) In the <;Display” setting, connect the external monitor through “Copy” mode and restart the computer.

2) Connect the external display in the “Extensions" setting in “Extended" mode with low or medium resolution set and then remove the display link.

Microsoft has discovered and tried to solve this problem. In the meantime, you can try the following alternatives:

1, put your notebook or tablet into sleep mode, and then wake up again.

2. Unplug the Mdp/DP/HDMI interface of the external monitor and re-access it, which may solve this display problem.

The above is a solution to the loss of the background of the external version of the Win10 1607 Anniversary Update. I hope to help everyone. If you have any questions, please leave a message, Xiaobian Will reply to you in time. Thank you very much for your support of this website!
