Desktop Duplication - second monitor black

[cyberstream]

Hello,

Is there a known limitation when using Desktop Duplication on Windows 10 (LTSC 1809) where the second monitor is blank? When turning it off, I can see the second monitor and interact with it without any problems.

Thanks!

What version are you using ? This was an issue in the first 1.2.2.2 test releases and fixed for update.
We tested the ddengine with 3 monitors on single and multiple video cards systems.

Else try the latest 1.2.2.3 available via this forum.

What's the data if the ddengine.dll ?
System with single or dual video card ( monitors are on the same video card ?)
What happen if you press the switch button . (left/Black/left+black)

Thanks all for your assistance. I tried the winvnc.exe from r1174 on the same machine and the problem is resolved. I will wait for 1.2.2.3 to be released.
