Hardware Requirements and Recommendations

This section has information on the following topics:

The decision about which hardware to use when setting up a video wall depends a great deal on how the video wall can be used. In the most basic sense, any multi-display setup can be used. However, when in need of a an increased number of displays, clip playback capabilities, live streams, or complex graphics, the demands on the hardware increases significantly. A video board is required for clip playback and input capabilities.

Utilizing the NVIDIA Quadro M6000 or P6000 graphics cards and the Matrix X.mio3 video board, Viz Engine support video wall configurations with up to 16k by 16k output resolution, and up to eight SDI inputs. Depending on the selected configuration, Viz Engine currently supports the following inputs and outputs for video walls:

  • Four to eight SDI inputs, with resolutions ranging from SD to 4K, with a maximum of eight 1080i or one 4K concurrent input.

  • Four to 16 DisplayPort or DVI outputs, with up to 4K resolution per output.

    Note: More GPUs require more bandwidth and therefore decrease the performance. Therefore, it is strongly recommended to use only one physical GPU and split the outputs (4*4K on M6000/ 4*5K on P6000) with additional hardware like a Datapath Device.

Minimum Hardware Configuration for Video Walls

  • HP Z800-series Desktop Workstation

  • NVIDIA Quadro M4000 graphics card

  • Matrox X.mio2 video board with optional X.RIO expansion module

  • NVIDIA Quadro Sync synchronization card

Recommended Configuration for Video Walls

  • HP Z8 Desktop Workstation

  • NVIDIA Quadro M6000 or P6000 graphics card

  • Matrox X.mio3 or Matrox DSX LE4 video board

  • NVIDIA Quadro Sync synchronization card

Note: Videowall configurations require a DVI Max Resolution license.

IP based Video Walls

xMIO5 based topology boards do not have a genlock connector anymore, they only synced using PTP. (Older xMIO3 IP boards still have a Genlock connector)
To correctly synchronize a videowall using xMIO5 boards, you will need

  • a valid PTP signal

  • a blackburst signal to synchronize the nVidia gSync board

  • a blackburst signal for any additional device (e.g. Signal processors or the displays)

All of these signals need to be driven from the same source. Therefore it is highly recommended to use a system generating PTP and Genlock sources from the same clock.

The following diagram illustrates a basic synchronization flow:
