I've reviewed the screenshots and I see on the screenshot with the Full Control window that both Display 1 and Display 2 are listed in the dropdown menu for the Remote Monitor switch. Could you please clarify if anything happens if you sel ect Display 2 or the Entire desktop options fr om the list?
I am also still experiencing this problem intermittently. It usually works, but occasionally when I connect, I see both screens and am unable to change the monitor using the menu. Restarting the remote utilities service and reconnecting has always resolved the issue (at least temporarily) for me.
Could you please confirm if the issue occasionally occurs when using the latest 126.96.36.199 Beta 2 version? If this is the case, could you please try recording a short video of the issue and send it to us to email@example.com? We will forward the video to our development department to see if there might be a fix for it.
In case if the issue occurs when using version 188.8.131.52 or any previous version (on any side of the connection), then please update it to the 184.108.40.206 Beta 2 version as well as the mechanism of fetching the remote monitors list was replaced in this release.
This problem went away for several months but seems to have returned with at least the most recent version (220.127.116.11), which I have on both my viewer and my host side. Same symptoms/behavior as before for me.
Please try enabling the Use legacy capture mode checkbox in the Host Settings -> Other tab and see if this helps to resolve the issue. After enabling the checkbox please make sure to restart Host in order for the changes to be applied.
Additionally, please make sure that the remote Host machine has the latest graphics card drivers installed.
Please let me know if the solutions above did not help and the issue persists.
