Introduction

Thank you for purchasing a StarTech.com VGA video

splitter. This product splits the VGA output from one

computer to 2, 4, or 8 VGA displays (depending on

the model purchased). Perfect for use with any VGA

monitor or projector, this product is ideal for auditori-

ums, tradeshow displays, kiosks, and any other appli-

cations that require the use of multiple monitors. It is

designed to maintain excellent video quality and

requires no software or the configuration of compli-

cated setup options.

Features

• Video bandwidth of 250 MHz

• Maximum resolution of 1920 x 1440 pixels

• Supports up to 3 levels of “daisy chaining”

• Maximum distance of 210 feet (65m)

Before You Begin

System Requirements

• A computer with VGA output

• 2/4/8 displays with VGA inputs

• 1 high-quality VGA “switchbox” cable for each

monitor to be connected, and 1 VGA male/female

cable for the source computer

Basic Setup

Before connecting the splitter to the source computer

and displays, you should ensure that the workspace

is configured so that the minimal amount of cable will

be used between the computer and the splitter, and

between the splitter and the displays. While the split-

ter will work at distances of up to 210 feet (65m) from

the connected displays, keeping the cable distance

between each device to the shortest possible length

will ensure you can use the highest possible resolu-

tion. While the splitter supports a maximum reso-

lution of 1920 x 1440 pixels, the maximum resolu-

tion you will be able to use for your application

will depend on the length and quality of the

cables used, and how many interference-causing

devices are nearby. You may not be able to use the

maximum resolution at longer distances. For the best

possible performance, keep the length of cable from

the source computer to the splitter to 6 feet (1.8m).

Connecting the computer to the splitter

Using a high-quality HD-15 VGA male-to-female mon-

itor cable (StarTech.com part number MXT101HQ),

connect the male end to the VGA out port on the

source computer. Connect the opposite end (female)

to the port marked Video In on the splitter.

Connecting the splitter to the displays

Using a high-quality HD-15 VGA switchbox male-to-

male cable (StarTech.com part number

MXT101MMHQ), connect one end to the cable to any

of the ports marked Video Out on the splitter.

Connect the opposite end to the VGA input on the

display. Repeat this process for each display to be

connected. You may also plug the display directly

into the splitter’s Video Out port if possible.

Powering the splitter

Connect the tip on the power adapter (provided) to

the port marked DC 9V on the video splitter. Connect

the opposite end to a wall outlet or other suitable

power source.

Once you have completed the steps above, you can

power on the displays. Each will now display the

image from the source computer.

Daisy Chaining Splitters

These splitters have the ability to be “daisy chained”

to one another so that the overall number of total dis-

plays is increased. You can have a maximum of 3

splitters daisy chained to one video source.

Complete the following steps to daisy chain two or

more video splitters:

Using a high-quality HD-15 VGA male-to-female mon-

itor cable (StarTech.com part number MXT101HQ),

connect the male end to any of the ports marked

Video Out on the source splitter. Connect the oppo-

site end (female) to the port marked Video In on the

next splitter in the chain. Repeat this process if you

wish to connect another splitter.
