2.5 Display Interfaces
The processor supports single eDP* interface and 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.
The technologies supported by the processor are listed in the following table.
Table 2-17. VGA and Embedded DisplayPort* (eDP*) Bifurcation Summary
Port S-Processor Line
eDP - DDIA
(eDP lower x2 lanes, [1:0])
Yes
VGA - DDIE
2
(DP upper x2 lanes, [3:2])
Yes
1
Notes:
1. Requires a DP to VGA converter.
2. DP-to-VGA converter on the processor ports is supported using external dongle only, display driver
software for VGA dongles which configures the VGA port as a DP branch device.
Table 2-18. Embedded DisplayPort (eDP*)/DDI Ports Availability
Ports Port Name in VBT S-Processor Line
2,3
DDI0 - eDP Port A Yes
DDI1 Port B Yes
DDI2 Port C Yes
DDI3 Port D Yes
DDI4 - eDP/VGA Port E Yes
1
Notes:
1. Port E is bifurcated from eDP, when VGA is used need to use available AUX (if HDMI is in used).
a. For example, DT can use eDP_AUX for VGA converter which is available as free Design but HPD
should be used as DDPE_HPD3.
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. N/A
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.
