I am using remote utilities on a laptop. Whenever I close the lid of the laptop the viewer PC screen will freeze. If I press logon again, a black screen will appear. The thumbnail in the viewer panel is correct. I have adjusted the power and sleep settings in Windows 10 to ensure that the laptop is always awake and also the settings for the screen are set to never turn off the screen. So a connection exists but the screen remains black. The hints that I found so far (reboot laptop, make sure on full control etc.) were tried in vain.
