Fix: RDP ‘Remote Desktop’ Black Boxes/Bars and Screen Size issue

Remote Desktop Connection Manager provides a great way of accessing remote computers and their files over the internet. However, you might face a few problems on your end while accessing the remote desktop. On your end, the screen of the remote desktop might not resize properly. This means that the screen might be really big (some of its parts will be out of your screen) or the screen might get really small. There are different variations of the screen problem but the point here is that the screen won’t be normal. There are cases where users might see black bars on the bottom and on the right side of the remote desktop. The black bars might vary from user to user. Some people might see bars on the edges of the screen while some people might see black bars/squares randomly spread on the screen. The black portions of the screen won’t block your interaction with the screen though. You will be able to click through the black box or black bar meaning if the black box or a black bar is appearing on top of a start button then you would be able to move your mouse there and click the start button.

There are a couple of things that can cause this. The size of the screen can be adjusted via the properties or settings of the Remote Desktop Connection Manager. The black bars or black squares can be caused by video driver issues. Another reason that might be causing these black boxes is the connection speed. Switching to appropriate connection settings from the Remote Desktop Connection Manager and changing a few more settings rectify that situation as well.

Bitmap Caching is an option available in the Remote Desktop Connection Client. This option basically lets the user store the images locally so the client doesn’t have to send the images or data over and over again.
