Skype Room Systems v2: known perf issue for Surface Pro (2017)-based devices

Skype Room Systems v2 devices based on the Surface Pro (2017) tablet may observe performance issues under meeting conditions where a combination of HDMI wired ingest sharing, dual front-of-room displays, and multiple remote video streams are being used.  Repro symptoms may not appear for 15 to 30 minutes after HDMI wired ingest sharing begins. Local symptoms of such performance issues include slow touch console keyboard response and dropped meetings.  Remote attendees may notice the room video rendered at a lower frame rate than normal.

 

Possible workarounds to alleviate these symptoms include:

- Desktop sharing into the meeting via the Skype for Business application (as a replacement for HDMI wired ingest).

- Reducing the front-of-room display configuration from dual to single screen.

 

The same symptoms have not been reproduced on Surface Pro 4 and non-Surface Pro-based systems.

 

Resolution: The Skype Room Systems Engineering Team is investigating a software-based solution to resolve this issue.  Release date for a potential fix is not determined.  I will keep this thread updated with any late-breaking changes in status.

    Agreed rodelmurex, but then Logitech SmartDock has flex coming soon to simplify cabling...

     

    Each option out there does 95% perfectly, just a different 95% depending on what you choose.

    Actually, using 1 Tv has no issue at all video + presentation . It just so happened that our china office has newly installed this device but they are using two TV . We have remove the the 1 tv display in china and test again and we don't encounter any issue .

    rodelmurex that's precisely the reason why it's a sporadic issue, overheating based on load. If you're only using a single screen, not presenting etc device does not overheat, throw more at it and issues arise. This is due to the Surface device disabling services to protect itself from overheating.

    Damien Margaritis I don't think so . using 1 TV works fine without any issue. its just dual display .

     

    we try to change to resolution of two tv's to 720p and seems it didnt disconnect or skype crash at the moment. 

     

    we will keep on testing tomorrow.

    I assume this is due to overheating issues with Surface Pro 5's which don't have fans, as opposed to Surface Pro 4's that do?

    thanks for the update. Our china office are all using 2 tv's and surface pro 2017  . We have experienced it today those you mention above .Anyway, i will ask my colleague to use 1 TV first and will test. Our main office are using mostly 1 TV without any issue except one room that is using 2 Tv.

     

    hoping for an update soon. By the way, is there a way i can make the skype app in windows mode so that i can minimize? we want to run wireshark on the device to investigate some network reconnecting issue.
