Intel Quick Sync Video (QSV) is a technology available on some Intel processors, that provides hardware acceleration for video encoding /decoding. QSV offloads video encoding/decoding to a dedicated hardware CPU core, providing faster results and reducing the video footprint on server CPU performanceand decoding. This technology provides faster and more energy efficient processing of video content.

    Depending on the BIOS version, it the option may be named differently (iGPU , Internal  Internal Graphics , Integrated Graphics  Graphics Adapter -  – PEG).


  2. In general,  the simultaneous use of the integrated graphics unit (iGPU) and external GPU has to be avoidedIt is not allowed to use an integrated graphics core and an external graphics card at the same time. In this case, to use Intel QSVQuick Sync Video, do as followsthe following:
    1. Enable Multi-Monitor in the BIOS settings.

    2. Connect a “Fake/Virtual” Monitor/Display on Windows and then connect it to your iGPU and select Extend desktop to this display in the Multiple displays list.

  3. Go to Settings → Options → User interface (1–2).
