Hi,
I am having a black screen issue on a Windows (18362) machine. Using Viewer 6.10.10.0 and Host of the same version
This issue only happens when the computer is using an external monitor (DisplayPort) and has it's main screen off (lid closed). I have not tried with both screens on, since this is a laptop in use and I cannot bother the user much.
Everything worked "fine" before using the external monitor, and no particular change to the machine could be involved.
Installing the display driver (and rebooting) did not change anything. However, using legacy capture mode does bring the screen back. I'm assuming this is not a plan for the long term (being legacy), so I would be interested into having this issue fixed.
The weird thing is that I can still see the screenshots from the machine on the address book.
I am aware that being a free user does not entitle me to any help, and I am very grateful for any help you will provide. Your software really saved me from headaches.

Hello Andy,
Thank you for your message.
As for the legacy mode - the difference between the default capture and legacy modes has to do with how the screen capture is processed deep inside the operating system. However, I'll forward your question to our development department and ask for their input on this.
In addition, here's a related troubleshooting KB article that might be useful as well.
Looking forward to your reply.
Thank you for your message.
Please note that the Monitor driver is only used for the Blank remote screen feature. In case if you don't use this feature we advise that you uninstall the Monitor driver.Installing the display driver (and rebooting) did not change anything.
Could you please confirm that enabling the Legacy capture mode did resolve the issue?However, using legacy capture mode does bring the screen back. I'm assuming this is not a plan for the long term (being legacy), so I would be interested into having this issue fixed.
