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.
• H/S-Processor Line processors supports eDP and up to 3 DDI supporting DP/
HDMI*.
• U-Processor Line supports eDP and up to 2 DDI supporting DP/HDMI*.
• AUX/DDC signals are valid for each DDI Port. (Two for U-Processor Lines, andthree
for HS-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.
2.5.2 eDP* Bifurcation
• eDP bifurcation is not applicable for U -Processor Line.
• eDP bifurcation for H/S-Processor Line can be used for: DP x2 upper lanes (DDIE)
for VGA support and eDP x2 lower lanes. Both eDP ports can be used
simultaneously.

3. 5xHPD (PCH) inputs (eDP_HPD, DDPB_HPD0, DDPC_HPD1, DDPD_HPD2, DDPE_HPD3) are valid for all
processor SKUs.
4. No Port D for U-Processor Line. DDI3_AUX are exists as reserved.
5. 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.
