For your information....
If you have any machines that have Q43/Q45 graphics and you just updated those machines to W10 1903, you will have a BLACK SCREEN if you try to Remote Desktop to those machines.
Accessing those machines locally does not have a problem.
If you do remote to any of those machines, and have a black screen, you can CNTL-ALT-END, select Task Manager, and kill the remote desktop process.
As we all know, the Q43/Q45 is not supported. So, a fix, if any, will have to come from Microsoft.
Al.Hill, Thank you sharing those details.
Thank you very much also for providing that feedback we are sure it will be very helpful for all the peers viewing this thread.
