SRS v2 2.0.2.0 input lag

The HDMI input feature of the Logitech SmartDock has quite a lag. We have a pc permenantly hooked up to the smartdock but the mouse movement is very slow and lagged behind. Is there any we can to do ...

Nope after 4 months of back and forth between MS and Polycom/Logitech

 

Microsoft have said its a design limitation and is working as intended. 

 

"We have got an update from our product group team that the " HDMI ingest does introduce extra latency due to the process of video capturing and UVC conversion. Per our PRD this process in HW should be less than 100ms. I don’t think the latency of the Polycom dock is significantly longer than others. Some people may perceive the mouse lag, but I’d expect it to be very mild."

 

HDMI ingest is slower than the actual screen that’s being presented. Hence this is a design limitation.

 

As per your last conversation with my Technical Lead Sandeep Jadhav, the issue is by design as confirmed by our product group team."

 

So not sure what we are going to do yet.
