VGA extender for four displays

The StarTech ST121UTP extends a single VGA source to two local and two remote monitors over Cat5e or better cabling. It reaches up to 150 metres with a 1024x768 image and shorter runs support 1280x1024 or 1440x900. The kit includes both extender units, two power adapters, a mounting bracket and rubber feet.

Cabling and resolution planning

Verify that your cable run uses solid-conductor Cat5e UTP or higher and does not exceed 150 metres. At the full distance the maximum supported resolution drops to 1024x768; 1280x1024 is available at 100 metres and 1440x900 at 50 metres. Each display requires a standard VGA connection.

Passive cooling and low power draw

The compact units measure 3.3 by 2.4 by 0.8 inches and weigh 181 grams with no moving parts, so they operate silently. Each side draws 0.6 amps at 9 volts DC from the supplied adapters, keeping heat output minimal in typical installations.

Questions about this item

Does the ST121UTP package include the Cat5e cables needed to link the local and remote units?

No, the box supplies the local unit, remote unit, two power adapters, a mounting bracket with screws, rubber feet and a manual; Cat5e or better UTP cable must be purchased separately.

Which resolution should I expect at the full 500 ft distance versus a shorter 150 ft run?

At 500 ft (150 m) the extender supports 1024 x 768; at 150 ft (50 m) it supports 1440 x 900, with 1280 x 1024 available at the intermediate 300 ft (100 m) range.

How many monitors can I actually drive at each end once the extender is installed?

The local unit provides one VGA input and two VGA outputs, while the remote unit provides two VGA outputs, so up to two displays can be connected at the local side and two at the remote side simultaneously.
