Four-port HDMI production switcher

The StarTech VS421HD20 routes four HDMI sources to one display, making it suited for presentation rooms, home-theatre racks or streaming desks where a single screen must show multiple 4K devices. It accepts sources up to 3840x2160 at 60Hz and passes 7.1 surround audio through the same cable.

4K 60Hz resolution ceiling

The switch tops out at 3840x2160 at 60Hz with support for 2560x1600, 1920x1200, 1920x1080 and 1280x720 at the same refresh rate. Buyers needing 4K at 120Hz, 8K at any refresh rate or HDR metadata pass-through will need a different class of switcher.

Fanless desktop operation

With no moving parts the unit runs silently on the included 100-240 V AC adapter that delivers 5 V at 2 A. The chassis stays cool enough for continuous use in ambient temperatures from 0 to 40 °C at 10-85 % relative humidity.

Questions about this item

What does 4K 60Hz mean for my sources and display?

The switch passes 3840x2160 at 60Hz from any connected source to the display without downscaling or frame-rate loss.

Which HDMI version does the VS421HD20 implement and what bandwidth limit applies?

It uses HDMI 2.0 ports, capping throughput at the 2.0 specification for 4K 60Hz 4:4:4 signals.

How much desk space and clearance does the unit need?

The chassis measures .80 by 4.80 by 2.00 inches and weighs .34 lb, so it fits on a shelf or rack shelf with minimal depth.
