• The processor supports only 3 streaming independent and simultaneous display
combinations of DisplayPort*/eDP*/HDMI*/DVI monitors. In the case where 4
monitors are plugged in, the software policy will determine which 3 will be used.
• Three High Definition Audio streams over the digital display interfaces are
supported.
• For display resolutions driving capability Refer Table 2-29, “Maximum Display
Resolution”.
• DisplayPort* Aux CH supported by the processor, while DDC channel, Panel power
sequencing, and HPD are supported through the PCH.

Notes:
1. All 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 Table above is partial List of the common Display resolutions, just for example.
The Link Bandwidth depends if the standards is Reduced Blanking or not.
If the Standard is Not reduced blanking - the expected Bandwidth will 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 the resolutions that can be supported in MST configurations, follow the below
guidelines:
a. Identify what is the Link Bandwidth (column right) according the requested Display
resolution.
b. Summarize the Bandwidth for Two of three Displays accordingly, and make sure the final
result is below 21.6 Gbps. (for HBR2, four lanes)
c. For special cases when x2 lanes are used or HBR or RBR used, refer to the tables in
Section 2.5.14 accordingly.
For examples:
a. Docking Two displays: 3840x2160 @ 60 Hz + 1920x1200 @ 60 Hz = 16 + 4.62 =
20.62 Gbps [Supported].
b. Docking Three Displays: 3840x2160 @ 30 Hz + 3840x2160 @ 30 Hz +
1920x1080 @ 60 Hz = 7.88 + 7.88 + 4.16 = 19.92 Gbps [Supported].
6. Consider also the supported resolutions as mentioned in Section 2.5.9 and Section 2.5.10.
