Switch between four HDMI video sources on a single display with support for Ultra HD resolutions. 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 60 Hz, making it the perfect solution for connecting four video sources to a display that has a limited number of HDMI 2.0 ports. The HDCP 2.2 HDMI switch lets you harness the High Dynamic Range (HDR) capability of your HDMI 2.0 video sources & deliver it to your UHD 4K60 display. Unlike many 4K switches that only support a 30 Hz refresh rate, this switch works with HDMI 2.0 displays with output resolutions of up to 3840 x 2160p at 60 Hz. Don't be fooled by a clever spin on old technology. Many HDMI switches support 4K but will only work at a 30 Hz refresh rate, or claim support for 60 Hz but heavily compress their signal to a lower 4:2:0 chroma subsampling in order to work at inferior bitrates. This 4K 60 Hz HDMI switch uses the latest components to offer full support for your HDMI 2.0 equipment, supporting true 4K resolution at 60 Hz with 4:4:4 chroma subsampling. Support for HDMI 2.0 devices means this switch can transmit bandwidth up to 18 Gbps, making it ideal for high-resolution computer tasks. The switch is backward compatible with 4K 30 Hz & 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. This switch ensures effortless operation with automatic switching that detects & 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 opera ...
