4-Port VGA Splitter (1 In, 4 Out, Powered)

Show one screen on four displays at once

A powered 4-port VGA splitter that takes one VGA source from a laptop or PC and duplicates it to four VGA outputs, so the same image shows on up to four monitors or projectors at the same time.

It is an active unit that buffers and amplifies the signal, so every screen stays clean and sharp instead of fading as you add displays.

This is a powered VGA splitter with one VGA HD15 female input and four VGA HD15 female outputs. You plug your computer's VGA output into the input, then run a VGA cable from each output to a monitor or projector.

The splitter copies the signal to all four outputs at once and shows the identical picture on every screen, which makes it a simple way to put one presentation in front of a large room.

It supports resolutions up to 1920x1440 at 60Hz and carries video only, because VGA has no audio channel, so any sound has to travel on a separate lead.

Being an active splitter rather than a passive one, it runs from an external power adapter that lets it amplify and regenerate the signal on each output, so the four screens do not go dim, fuzzy or ghosted the way a cheap passive splitter would when it is stretched across several displays.

It works with any monitor or projector that has a standard VGA HD15 socket, which makes it a good fit for the older projectors and screens still common in Sri Lankan halls, classrooms and offices.
