Hi @saboreq,
Can you tell us your current network connection? wired/wireless?
Can you also please monitor the CPU, memory and network load of spacedeskService.exe in your task manager while spacedesk viewers are connected?
And please also send us the diagnostic logs of your primary machine while spacedesk videowall is active.
Just open the spacedesk Driver Console -> Diagnostics, then click the “Save All Information” button.
PS: Saving all information will take a few seconds, then please send us the whole folder which contains all the diagnostic logs collected.
Please right-click the folder -> Send to -> Compressed (zipped) folder, then attach the *.zip file in your next reply.
