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.

    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.

    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?

    Deleted - The only change in 3.1.104.3 was an updated version of the recovery tool.  The application update itself contained in this MSI will bring you up to 3.1.104.0.

     

    We're evaluating a fix to the perf issue described in the article above.  I'll publish an update on status this week.

    Tristan Griffiths We have a 3.1.112.0 update that's been released to address the issue.  It's currently throttled up to 20%.  We'll monitor results a little longer before throttling up to 100%.

    Jed Ellerby When we release an update, we typically do so in a gradual manner to devices in the field.  "20% throttling" means that 20% of deployed devices are being offered the update.

    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.
