Video Payload Resolution RRS feed

  • Question

  • Hello,we have an installation with Lync Server 2013 and SkypeforBusiness client.

    Target client machine:

    CPU: core i7

    RAM: 8GB

    Video Card: Intel HD 530

    Webcam: Microsoft LifeCam Studio

    OS: Windows 7 32bit

    We have noticed that only one client does a Full HD with video payload resolution logged into Lync in tracing (Lync-UccApi-0.UccApilog) to 1920x1080. The Others client connect only to HD resolution (720p).

    We ran DxDiag tool and in the log does not appear di XDVA2 mode, but only "DXVA-HD: Supported".

    How is possible to verify if Windows or Lync client is able to use the full hardware acceleration with XDVA2?

    Thank you in advance
