Colorlight VX20 LED video processor
Colorlight VX20 combines 4K video processing with LED display control for stages, rental screens and commercial exhibitions. It supports up to 13.1 million pixels, twenty Gigabit Ethernet outputs and four 10G fiber ports. Three 4K layers, preview/program views and Multiviewer help operators prepare and monitor live layouts.
Prepare scenes before taking them live
In PVW & PGM mode, an operator can edit the preview image and send it to the display with the Take or Cut controls. In PGM Only mode, layer changes apply to the display while appearing in Multiviewer. Scaling, cropping, Picture-in-Picture, overlay opacity and fade transitions support different presentation layouts.
The processor supports background images, logos and OSD. Its web-based controls work with Windows, macOS and Linux through a network connection. Video processor, fiber optic transceiver and Bypass modes support different signal paths.

Fiber 1 and Fiber 2 serve as the primary outputs for Ethernet groups 1–10 and 11–20. Fiber 3 and Fiber 4 copy or back up those primary fiber outputs. In the documented output routing, primary fiber ports take precedence when both fiber and Ethernet are connected. Check the selected mode and module configuration before installation.
Frequently asked questions
Can Colorlight VX20 display three 4K layers at once?
Yes. The specification lists three simultaneous layers, each at 4K resolution, with scaling, cropping and Picture-in-Picture support. Total LED loading remains limited to 13.1 million pixels.
Can all four additional HDMI inputs run as HDMI 1.4 simultaneously?
No. The specification footnote limits simultaneous operation to two HDMI 1.4 inputs or four HDMI 1.3 inputs. This is separate from the two HDMI 2.0 inputs.
How does VX20 optical backup work?
Fiber 1 and Fiber 2 are primary outputs for Ethernet groups 1–10 and 11–20. Fiber 3 and Fiber 4 can copy or back up their respective primary outputs. Optical modules are optional.
What is the difference between VX20 processor and Bypass modes?
Video processor mode processes multiple sources and outputs three selected sources, with one frame of delay by default. Bypass mode selects one source for output and is documented as having zero-frame delay.
Can VX20 be controlled from a Mac or Linux computer?
Yes. The specification describes web-based control compatible with Windows, macOS and Linux using a network connection, without additional control software installation.
