2.5 Display Interfaces
2.5.1 DDI Configuration
The processor supports single eDP* interface and 2 or 3 DDI interfaces (depends on
segment).
• DDI interface can be configured as DisplayPort* or HDMI*.
• Each DDI can support dual mode (DP++).
• Each DDI can support DVI (DVI max resolution is 1920x1200 @ 60 Hz).
• The DisplayPort* can be configured to use 1, 2, or 4 lanes depending on the
bandwidth requirements and link data rate.
• DDI ports notated as: DDI B, C, D.
• S-Processor Line processors supports eDP and up to 3 DDI supporting DP/HDMI.
• AUX/DDC signals are valid for each DDI Port. (three for S-Processor Lines)
• Total Five dedicated HPD (Hot plug detect signals) are valid for all processor SKUs.
Note: SSC is supported in eDP*/DP for all Processor Lines.
Note: The processor platform supports DP Type-C implementation with additional discrete
components.

Notes:
1. For more information, see Section 2.5.2, “eDP* Bifurcation”
2. 3xDDC (DDPB, DDPC, DDPD) are valid for all the processor SKUs .
3. 5xHPD (PCH) inputs (eDP_HPD, DDPB_HPD0, DDPC_HPD1, DDPD_HPD2, DDPE_HPD3)
are valid for all processor SKUs.
4. VBT provides a configuration option to select the four AUX channels A/B/C/D for a given port,
based on how the aux channel lines are connected physically on the board.
