DisplayPort - 4K 60Hz
Product ID: VS421HDDP
This 4-input HDMI video switch lets you share an HDMI 2.0 display or projector with three HDMI video
sources and one DisplayPort video source.
Enjoy Astonishing Picture Quality
The multi-port HDMI switch lets you deliver the capabilities of your HDMI 2.0 video sources to your UHD
4K60 display. Unlike many 4K switches that only support a 30Hz refresh rate, this switcher box works
with HDMI 2.0 displays with output resolutions of up to 4096 x 2160 at 60Hz.
With full support for HDMI 2.0 devices and 4:4:4 chroma subsampling, this 4K HDMI video switcher
supports a bandwidth up to 18Gbps. As well, the switch supports DisplayPort 1.2 with HBR2, making it
ideal for high-resolution computer tasks.

Flexible Input Options
This multi-port video switcher offers four input options, including one DisplayPort and three HDMI ports,
enabling you to switch from one of four sources to your HDMI video display. The mix-and-match input
options provide users with a flexible solution so they are not limited to one specific input.
Hassle-Free Operation with Automatic Switching
This HDMI switcher box ensures effortless operation with automatic switching that detects and selects a
newly connected device. It's perfect for automatically switching to a 4K media player such as a 4K UHD
Blu-ray™ player as soon as it's switched on.
This automatic HDMI switch also supports manual operation, using the included IR remote control or the
built-in front-panel toggle switch.
VS421HDDP is backed by a 2-year StarTech.com warranty and free lifetime technical support.
