- All the above is related to bit depth of 24.
- The data rate for a given video mode can be calculated as- Data Rate = Pixel Frequency * Bit Depth.
- The bandwidth requirements for a given video mode can be calculated as: Bandwidth = Data Rate * 1.25 (for 8b/10b coding overhead).
- 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 - To calculate what are the resolutions that can be supported in MST configurations, follow the below guidelines:
- Identify what is the link bandwidth column according to the requested display resolution.
- 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: - Docking two displays: 3840x2160@60 Hz + 1920x1200@60hz = 16 + 4.62 = 20.62 Gbps [Supported]
- Docking three displays: 3840x2160@30 Hz + 3840x2160@30 Hz + 1920x1080@60 Hz = 7.88 + 7.88 + 4.16 = 19.92 Gbps [Supported].
