  • Startech 4K 60Hz 4-Port HDMI Automatic Switch | VS421HD20

    This 4-port HDMI video switch lets you share an HDMI 2.0 display or projector with four HDMI 2.0 video sources. The switch features four independent video inputs that can each support 4K resolution at 60Hz, making it the perfect solution for connecting four video sources to a display that has a limited number of HDMI 2.0 ports.

    VS421HD20

    Astonishing picture quality with support for Ultra HD 4K at 60Hz
    The HDCP 2.2 HDMI switch lets you harness the High Dynamic Range (HDR) capability of your HDMI 2.0 video sources and deliver it to your UHD 4K60 display. Unlike many 4K switches that only support a 30Hz refresh rate, this switch works with HDMI 2.0 displays with output resolutions of up to 3840 x 2160p at 60Hz.

    Don't be fooled by a clever spin on old technology. Many HDMI switches support 4K but will only work at a 30Hz refresh rate, or claim support for 60Hz but heavily compress their signal to a lower 4:2:0 chroma subsampling in order to work at inferior bitrates. This 4K 60Hz HDMI switch uses the latest components to offer full support for your HDMI 2.0 equipment, supporting true 4K resolution at 60Hz with 4:4:4 chroma subsampling. Support for HDMI 2.0 devices means this switch can transmit bandwidth up to 18Gbps, making it ideal for high-resolution computer tasks. 

    The switch is backward compatible with 4K 30Hz and 1080p displays, which ensures that it will work with lower resolution displays such as TVs or projectors around your site or in a digital signage application.

    Hassle-free Operation with automatic switching
    This switch 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. In your classroom or office boardroom, the automatic switch makes it easy to share your projector between multiple sources, which encourages on-the-fly collaboration among colleagues.

    The HDMI switch also supports manual operation, using the included IR remote control or the built-in front-panel toggle switch.

    The VS421HD20 is backed by a 2-year StarTech.com warranty and free lifetime technical support.

    Applications
    Share 4K60 display with four different video sources
    Collaborate on the fly with colleagues, by connecting multiple users to the same display and switching between input devices
    Use in digital signage applications to display multiple source devices at different times
