ASRock A55M-DGS: 2. Installation

2.6 Dual Monitor and Surround Display Features

Dual Monitor Feature

This motherboard supports dual monitor feature. With the internal VGA output sup-

port (D-Sub and DVI-D), you can easily enjoy the benets of dual monitor feature

without installing any add-on VGA card to this motherboard. This motherboard also

provides independent display controllers for D-Sub and DVI-D to support dual VGA

output so that D-Sub and DVI-D can drive same or different display contents.

To enable dual monitor feature, please follow the below steps:

1. Connect D-Sub monitor cable to D-Sub port on the I/O panel, or connect DVI-D

monitor cable to DVI-D port on the I/O panel.

DVI-D portD-Sub port

2. If you have installed onboard VGA driver from our support CD to your system

already, you can freely enjoy the benets of dual monitor function after your

system boots. If you haven’t installed onboard VGA driver yet, please install

onboard VGA driver from our support CD to your system and restart your

computer.

When you playback HDCP-protected video from Blu-ray (BD) or

HD-DVD disc, the content will be displayed only in one of the two

monitors instead of both monitors.

Surround Display Feature

This motherboard supports surround display upgrade. With the internal VGA output

support (D-Sub and DVI-D) and external add-on PCI Express VGA cards, you can

easily enjoy the benets of surround display feature.

Please refer to the following steps to set up a surround display environment:

1. Install the PCI Express VGA cards on PCIE1 slot. Please refer to page 13 for

proper expansion card installation procedures for details.

2. Connect D-Sub monitor cable to D-Sub port on the I/O panel, or connect DVI-D

monitor cable to DVI-D port on the I/O panel. Then connect other monitor cables

to the corresponding connectors of the add-on PCI Express VGA cards on PCIE1

slot.

3. Boot your system. Press <F2> or <Del> to enter UEFI setup. Enter “Share

Memory” option to adjust the memory capability to [32MB], [64MB], [128MB],

[256MB] or [512MB] to enable the function of D-sub. Please make sure that

the value you select is less than the total capability of the system memory. If you

do not adjust the UEFI setup, the default value of “Share Memory”, [Auto], will

disable D-Sub function when the add-on VGA card is inserted to this

motherboard.

4. Install the onboard VGA driver and the add-on PCI Express VGA card driver to

your system. If you have installed the drivers already, there is no need to install

them again.

5. Set up a multi-monitor display.

®

For Windows

XP / XP 64-bit OS:

Right click the desktop, choose “Properties”, and select the “Settings” tab

B. Right-click the display icon in the Display Properties dialog that you

wish to be your primary monitor, and then select “Primary”. When

you use multiple monitors with your card, one monitor will always be

Primary, and all additional monitors will be designated as Secondary.

C. Select the display icon identied by the number 2.

D. Click “Extend my Windows desktop onto this monitor”.

E. Right-click the display icon and select “Attached”, if necessary.

F. Set the “Screen Resolution” and “Color Quality” as appropriate for the

English

second monitor. Click “Apply” or “OK” to apply these new values.

G. Repeat steps C through E for the diaplay icon identied by the number

one to four.

of display icons determines how you move items from one monitor to another.

HDCP Function

HDCP function is supported on this motherboard. To use HDCP

function with this motherboard, you need to adopt the monitor

that supports HDCP function as well. Therefore, you can enjoy

the superior display quality with high-denition HDCP

encryption contents. Please refer to below instruction for more

details about HDCP function.

What is HDCP?

HDCP stands for High-Bandwidth Digital Content Protection,

®

a specication developed by Intel

for protecting digital

entertainment content that uses the DVI interface. HDCP is a

copy protection scheme to eliminate the possibility of

intercepting digital data midstream between the video source,

or transmitter - such as a computer, DVD player or set-top box -

and the digital display, or receiver - such as a monitor, television

or projector. In other words, HDCP specication is designed to

protect the integrity of content as it is being transmitted.

Products compatible with the HDCP scheme such as DVD

English

players, satellite and cable HDTV set-top-boxes, as well as few

entertainment PCs requires a secure connection to a compliant

display. Due to the increase in manufacturers employing HDCP

in their equipment, it is highly recommended that the HDTV or

LCD monitor you purchase is compatible.

3 CIR sensors in different angles

1. Only one of the front USB port can support CIR function. When

the CIR function is enabled, the other port will remain USB

function.

2. Multi-Angle CIR Receiver is used for front USB only. Please do

not use the rear USB bracket to connect it on the rear panel.

Multi-Angle CIR Receiver can receive the multi-direction infrared

signals (top, down and front), which is compatible with most of

the chassis on the market.

3. The Multi-Angle CIR Receiver does not support Hot-Plug

function. Please install it before you boot the system.

2.8 Jumpers Setup

The illustration shows how jumpers are

setup. When the jumper cap is placed on

pins, the jumper is “Short”. If no jumper cap

is placed on pins, the jumper is “Open”. The

illustration shows a 3-pin jumper whose

pin1 and pin2 are “Short” when jumper cap

is placed on these 2 pins.

Jumper Setting Description

Clear CMOS Jumper

(CLRCMOS1)

(see p.2, No. 26)

Clear CMOSDefault

Note: CLRCMOS1 allows you to clear the data in CMOS. To clear and reset the

system parameters to default setup, please turn off the computer and unplug

the power cord from the power supply. After waiting for 15 seconds, use a

jumper cap to short pin2 and pin3 on CLRCMOS1 for 5 seconds. However,

please do not clear the CMOS right after you update the BIOS. If you need

to clear the CMOS when you just nish updating the BIOS, you must boot

up the system rst, and then shut it down before you do the clear-CMOS ac-

tion. Please be noted that the password, date, time, user default prole, 1394

GUID and MAC address will be cleared only if the CMOS battery is removed.
