B.2 LVDS
LVDS is an electrical signaling system that can run at very high speeds over inexpen-
sive twisted-pair copper cables. It was introduced in 1994, and has since become
very popular in computers, especially in very high-speed networks and computer
buses.
The ARK-3440 supports up to 48-bit LVDS display mode up to UXGA panel resolu-
tion, with transmit clock frequency ranges from 25MHz to 112MHz. The default set-
ting for "IGD - Boot Type" is "CRT + EFP". Please refer to Chapter 2/2.3.5 “LVDS
Connector” for setup details.
B.3 Dual Display
A multiple monitor setup increases the net display area of a system and can be an
inexpensive way of improving computer usage. Resulting display area after upgrad-
ing to a multi-monitor configuration is limited by the size, resolution, and number of
monitors. The two monitors used can be of different types (CRT+EFP, CRT+LFP)
and different sizes. The operating system manages the monitors' resolutions inde-
pendently.
