Colorlight CL-VX20 4K LED Video Processor

The CL-VX20 boasts robust video processing capabilities, supporting a load capacity of up to 13.1 million pixels, with a maximum width of 16,384 pixels and a maximum height of 8,192 pixels. The device offers 3 work modes— Video Processor, Fiber Optic Transceiver, and Bypass—making it ideal for stage rentals, commercial events, and exhibitions.

The CL-VX20 features multiple inputs (HDMI 2.0, DP 1.2, 12G-SDI, HDMI 1.4) and outputs (1G Ethernet, 10G fiber), offering exceptional image processing that supports 8/10/12-bit video input and 8/10-bit output. It also supports HDR technology, image cropping, high-fidelity video scaling, BKG, OSD, and logos. The device ensures reliable, intuitive operation and maintenance management by integrating HD Multiviewer, input hot backup, processor redundancy, data backup, fiber port redundancy, Ethernet port redundancy, dual canvas views, and multiple ports. All these make it a perfect fit for medium-to-high-end rentals, large-scale events, and fine-pitch LED screens.

The CL-VX20 can be controlled via the front panel touch screen, iSet, and web app. The web-based control is compatible with Windows, macOS, and Linux, without extra software installation.
