VGA signal extension over Cat5 cabling

The StarTech.com ST121UTPEP kit transmits a VGA signal from a single source to one remote display using Cat5 UTP cable. It includes a local transmitter, a remote receiver, a mounting bracket, a VGA cable and a universal 12 V DC power adapter. The aluminium enclosures measure 5.4 by 3.9 by 1 inches and weigh 36 g each. This point-to-point extender is designed for digital signage, classrooms or meeting rooms where the display sits far from the computer.

Installers needing up to 80 metres reach

The system supports 1920 x 1200 or 1600 x 1200 at 50 metres and 1280 x 1024 or 1024 x 768 at the full 80 metres. Cat5e UTP cabling is recommended for best results. It does not carry audio, cannot be daisy-chained and provides only a single local and single remote connection. Buyers who need audio transmission, multiple remote displays or longer distances should consider a different solution.

Maximum resolution at your cable length

Resolution drops as the Cat5 run increases, so the distance between source and display is the specification that decides suitability. At 50 metres you can use 1920 x 1200; at 80 metres you are limited to 1280 x 1024. Cable quality directly affects the achievable resolution, so verify the run length before purchase.

Questions about this item

Will the Cat5 cables or power adapter need periodic replacement during long-term use?

The kit includes a 12 V 0.6 A universal power adapter and uses standard Cat 5 UTP cabling; solid-core Cat 5e is recommended for best signal integrity over the full 80 m run.

At the full 80 m distance, which resolution limit appears first?

At 80 m (250 ft) the maximum supported resolution is 1280 x 1024; higher resolutions such as 1920 x 1200 are only guaranteed up to 50 m (164 ft).

How much heat or fan noise does the transmitter and receiver produce when running continuously?

Both units are passively cooled in aluminium enclosures measuring 5.4" x 3.9" x 1" and weighing 36 g, so they generate no fan noise and minimal heat during all-day operation.
