Multi-Port HDMI Switch Box | Automatic Switcher | IR Remote Control

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.

The StarTech.com Advantage

- Experience astonishing picture quality with support for resolutions up to 4K 60Hz

Returns FAQs

What is your returns criteria?
14 days from date of receipt, or expected date of receipt on non-tracked items.

How do I go about returning my order?
Please contact us via our contact page with your order number. We will provide you with an RMA number and return instructions, including your return deadline and whether a freepost label applies to your order.

Do I need to contact you before returning my order?
