black screen on viewer when closing laptop lid

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.

Hello Jurgen,

Thank you for your message.

Which program version do you use (Viewer and Host)? Also, dry install (or uninstall, if installed) the Host monitor driver. You can do so in Host settings -> Driver tab.

Hello.  I'm having this same problem.

If the lid on the laptop is closed, I get a black screen on the remote viewer.  Note that closing the lid during an active remote viewer session interrupts the session - the desktop on the viewer is no longer responsive.

In this case, I'm using remote utilities on a Dell Inspiron 7348 2-in-1 notebook running Windows 10 Pro.

Note that Windows Remote Desktop works regardless of whether the lid is opened or closed.  I'm pretty sure this isn't a power-down or sleep mode issue.

I have tried with the remote utilities display driver installed and not installed.  No change in behavior, even after restarting the computer.

Any ideas?

Hello David,

Thank you for your message.

Could you please clarify if you can still see/refresh remote screen previews on the thumbnails in the Viewer address book even if you close the remote computer lid?

If this is the case, please try enabling the Use legacy capture mode feature in the Settings for Host -General - Other tab:


Let me know if the problem persists.

I can use the View > Update previews feature to successfully update the thumbnails in the address book when the lid is closed and the viewer is "unresponsive".  So it looks like interactions on the viewer are taking place (mouse and keyboard actions), but the viewer is not updating the image.

Good news... I enabled legacy mode and restarted the notebook with the lid opened.  I connected with the viewer and confirmed that with lid open operation is normal.  Then I closed the lid, and the viewer continued to function normally!

My last test was to restart the computer with the lid closed and confirm that the viewer was still functional, which it was.

It seems legacy mode was the answer for my issue.  Thanks very much for the excellent tech support!
