ARK-3400 User Manual 60B.1 IntroductionThe ARK-3400 has an onboard Intel 910GMLE chipset for its PCIE controller. It sup-ports LVDS & DVI displays and conventional analog CRT monitors with 128 MBframe buffer shared with system memory. The VGA controller can drive CRT displayswith resolutions up to 1600 x 1200 @ 85 Hz and 2048 x 1536 @ 75 Hz and support24/48 bits LVDS display mode up to UXGA panel resolution with frequency rangefrom 25 MHz to 112 MHz.Figure B.1 BIOS VGA settingB.2 LVDSLow-voltage differential signaling, or LVDS, is an electrical signaling system that canrun at very high speeds over inexpensive twisted-pair copper cables. It was intro-duced in 1994, and has since become very popular in computers, where it forms partof very high-speed networks and computer buses.The ARK-3400 support 24/48 bits LVDS display mode up to UXGA panel resolutionwith frequency range from 25-MHz to 112-MHz. Refer to Chapter 3 “BIOS Operation”to find out how to change this setting. The default setting of “Boot Display” is “CRT”.B.3 Dual DisplayA multiple monitor setup increases the net display area of a system and can be aninexpensive way of improving computer usage. Resulting display area after upgrad-ing to a multi-monitor configuration is limited by the size, resolution and number ofmonitors. The monitors used for multi-monitor can be different types (CRT+LFP orCRT+DVI) and sizes. The operating system manages the monitors' resolutions inde-pendently.B.3.1 Display modes Clone modeInitially on PCs, the multiple output interface was designed to display the same imageon all output interfaces (sometimes referred to as mirroring or cloning). This reflectedthe fact that these video cards were originally used in presentations where the usertypically had his or her face to the audience with a duplicate of the projected imageavailable to the presenter.
