We got users complaining that accessing remote client on Remote Desktop does not bring up anything. When I try logging in to its Azure AVD, it opens up with a black screen and disappears in a second.
A simple start and stop on Azure portal seems to have fixed the problem. A restart did not fix it though. But, I am not sure why it happened in the first place and couldn't find a reason for it. Could anyone offer some suggestions please?
I tried to reproduce same in my environment. I got same error.
To resolve this issue, try the below.
The reason of this issue is slow sign-in process A black screen will appear for a while, until the regular desktop appears.
When the back screen shows to return to the previous screen, press CTRL + ALT + END. This launches Task Manager you will see the Desktop right away after Task Manager is called like below:
Make sure to disable the Bitmap Caching on the Remote Desktop Protocol (RDP) client like below.
Persistent bitmap caching is the combination of memory caching and glyphs. It will be reused throughout client sessions and also provide a bigger amount of cache space, which will result in a black screen.
And try to adjust Display size of your remote host's display like below:
Now I am able to connect RDP without any issue like below.
