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 congured 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
splitter 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 resolution. While the splitter supports a maximum
resolution of 1920 x 1440 pixels, the maximum resolution 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 monitor 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-tomale 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 displays 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 monitor cable
(StarTech.com part number MXT101HQ), connect the male end to
any of the ports marked Video Out on the source splitter. Connect
the opposite 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.
