2.3.5.2.
Display Resolution
The following table lists the maximum display resolution of the supported display interfaces.
Display Interfaces
Maximum Resolution
eDP
3840 x 2160 @ 60 Hz
DP 1.2 (++)
4096 x 2160 @ 60 Hz
HDMI 1.4
3840 x 2160 @ 30 Hz
DVI-D
3840 x 2160 @ 30 Hz
At 4K/UHD resolution, to increase link margin a DP redriver on the carrier is recommended.
2.3.6.
LVDS
Single channel LVDS with one pixel per clock and up to 24-bit color is available. The eDP to LVDS bridge is only
necessary for LVDS support and can be removed if LVDS signals are optionally overlaid with eDP signals.
The following table lists the basic LVDS features.

2.3.7.
Audio
The Intel HDA link allows for a maximum of one codec to be connected.
2.3.8.
PCI Express (PCIE) Lanes [0-3]
Four high-speed PCI Express Gen2.0 lanes support the PCIe lane configurations options (4 x1), (2 x1 + 1 x2), (2 x2), and
(1 x4) allowing for up to four separate external PCI devices.
The default configuration is (4x1) and supports four separate PCI devices if LAN is not supported. If LAN is supported,
only three external PCI devices can be used, as LAN uses the fourth PCIe lane (PCIe #4).
The following table lists the supported PCI Express lane configurations.
