Multi-Stream Transport (MST)

  • The processor supports Multi-Stream Transport (MST), enabling multiple monitors to be used via a single DisplayPort connector.
  • Maximum MST DP supported resolution:

Notes:
  1. All the above is related to bit depth of 24.
  2. The data rate for a given video mode can be calculated as- Data Rate = Pixel Frequency * Bit Depth.
  3. The bandwidth requirements for a given video mode can be calculated as: Bandwidth = Data Rate * 1.25 (for 8b/10b coding overhead).
  4. The link bandwidth depends if the standards is reduced blanking or not.

    If the standard is not reduced blanking - the expected bandwidth may be higher.

    For more details, refer to VESA and Industry Standards and Guidelines for Computer Display Monitor Timing (DMT). Version 1.0, Rev. 13 February 8, 2013

  5. To calculate what are the resolutions that can be supported in MST configurations, follow the below guidelines:
    1. Identify what is the link bandwidth column according to the requested display resolution.
    2. Summarize the bandwidth for two of three displays accordingly, and make sure the final result is below 21.6 Gbps. (for example: 4 lanes HBR2 bit rate)

    For example:

    1. Docking two displays: 3840x2160@60 Hz + 1920x1200@60hz = 16 + 4.62 = 20.62 Gbps [Supported]
    2. Docking three displays: 3840x2160@30 Hz + 3840x2160@30 Hz + 1920x1080@60 Hz = 7.88 + 7.88 + 4.16 = 19.92 Gbps [Supported].

Notes:
  1. Maximum resolution is based on the implementation of 4 lanes at HBR3 link data rate.
  2. bpp - bit per pixel.
  3. Resolution support is subject to memory BW availability.
  4. Resolutions will consume two display pipes.
