Graphics (LVDS or eDP, and DP++)
The COMe-mEL10 supports up to two simultaneous displays on the Digital Display Interface (DDI), where DDIO (port A)
is LVDS by default with the option to overlay to eDP requiring a hardware assembly and DDI1 (port B) supports DP++.
The following table lists the display features.
DDI

Description
Max. Resolution
DDI0 (port A) LVDS (default)
Single channel 24-bit color (1 pixel per clock)
1920 x 1200 @ 60Hz
eDP (option)
eDP overlay option requires hardware assembly
4096 x 2160 @ 60Hz
DDI1 (port B)
DP 1.2 V (DP++)
4K resolution with multiple active displays
4096 x 2160 @ 60Hz
Supported Flat panels with Extended Display identification Data (
EDID)/DisplayID.
It is recommended to only use a DP-to-HDMI or DP-to-DVI passive adapter compliant to the
VESA DP Dual-Mode standard. Display detection issues may occur with use of with FET level
shifter adapters for DDC translation.
At 4K resolution, to increase link margin a DP redriver on the carrier is recommended.
