Colorlight VX20 is a professional-grade video wall processor built for real-time control of LED displays in staging, rental, and commercial environments. Unlike basic scalers or switchers, the VX20 processes high-resolution video inputs—up to 4K at 60Hz—and outputs them across multiple LED panels with precise synchronization and minimal latency.

As part of Colorlight’s VX series, it functions primarily as an LED video processor, handling tasks like windowing, layer mixing (Main/PIP1/PIP2), frame rate conversion, and signal redundancy. It supports three operational modes:

• Video processor mode (full processing for LED walls),
• Bypass mode (pixel-perfect pass-through without processing),
• Fiber optic transceiver mode (for long-distance signal extension).

Users manage the VX20 through a web-based interface accessible from any device on the same network—no additional software required. This makes it especially useful for live events where quick setup and remote control are essential.

Understanding the technical capabilities of the Colorlight VX20 helps determine if it fits your project’s resolution, input, and reliability requirements. Below is a breakdown of its key specifications based on official documentation:

• The VX20 accepts standard 4K signals from cameras, media servers, or laptops via HDMI 2.0 or DisplayPort 1.2.
• It can handle non-standard resolutions often used in creative LED setups (like ultra-wide or portrait-oriented walls) thanks to custom EDID support.
• While it doesn’t support HDR or interlaced video, this is rarely a limitation in professional staging environments where progressive, SDR content dominates.
• Audio is passed through only on HDMI 3—useful for monitoring but not for multi-channel audio routing.

Colorlight VX20 video wall processor delivers field-tested functionality for live events, broadcast, and fixed LED installations. As a full-featured LED video processor, it combines real-time control, redundancy, and web-based management in a single 1U chassis.

• Video Processor Mode: The VX20 processes up to three inputs (Main + PIP1 + PIP2) and outputs to LED receiving cards with just 1-frame latency—ideal for dynamic stage visuals.
• Bypass Mode: Provides zero-latency, pixel-perfect pass-through for critical feeds like camera returns or IMAG.

• Fiber Transceiver Mode: Extends signals over long distances by receiving from another Colorlight LED processor via fiber and retransmitting over Ethernet.

• Supports dual-unit processor redundancy: Connect two VX20 units (primary + backup) to the same display for automatic failover—no external switcher needed.
• Dual SFP+ fiber ports allow signal duplication or backup paths.
• Dual Gigabit Ethernet ports ensure network continuity during cable faults.

Access the full interface from any device on the same network using a browser—no proprietary software. This makes the Colorlight VX20 easy to configure from a laptop backstage or a tablet in the control booth.

• Upload custom background images or set solid colors (with R/G/B input) for clean standby screens.
• Add scrolling text overlays (OSD) with adjustable speed, direction, opacity, and position—useful for lower-thirds or event branding.

The front-panel HDMI OUT shows PVW, PGM, and all input sources simultaneously, giving operators immediate visual feedback without needing a separate multiviewer.

Colorlight VX20 video wall processor isn’t just about handling signals—it directly improves reliability, flexibility, and operational efficiency in real-world LED deployments. Here’s how it makes a measurable difference on site.

Many LED processors downscale 4K sources to HD before output, creating quality loss. The VX20 accepts native 3840×2160@60Hz input and maps it pixel-accurately across your LED array—critical when using high-resolution media servers or broadcast feeds for stage backdrops or corporate events.

With built-in layering (Main + PIP1 + PIP2), you can overlay graphics, lower-thirds, or backup cameras without adding external switchers or mixers. This simplifies cabling, reduces points of failure, and cuts setup time—especially valuable in fast-turnaround rental scenarios.

As an LED video processor, the VX20 includes multiple redundancy layers:

• Dual-unit failover ensures your show continues if one unit fails.
• Fiber 3/4 ports provide backup data paths in fiber transceiver mode.
• Dual LAN ports maintain network control even if one cable is damaged.
• These features are not theoretical—they prevent costly blackouts during live performances or broadcasts.

The web UI lets operators adjust scaling, position, or source selection from any device on the network. Need to swap a camera feed mid-event? No need to climb scaffolding—just open a browser on your phone. This remote access capability is especially useful for large or elevated video walls.

When no program signal is active, the VX20 video wall processor can display a custom background or solid color—no blank screen or “no signal” message. You can also add scrolling text (e.g., event name, sponsor logo) via OSD, turning idle time into branding opportunity.

If you’re already using Colorlight receiving cards (like the HUB75-based RX series), the VX20 integrates out of the box. It outputs directly over Ethernet using standard protocols—no gateway or converter needed.

Installing the Colorlight VX20 video wall processor takes minutes when you follow this practical workflow. No special software is required—just a network cable and a web browser.

• Colorlight VX20 unit
• Power supply (included)
• HDMI or DisplayPort source (e.g., media server, laptop, camera)
• Ethernet cables (Cat6 recommended)
• LED receiving cards (e.g., Colorlight RX series)
• Computer or tablet for configuration

• Install the VX20 in a 19″ rack or place it on a stable surface with ventilation.
• Connect the included power adapter and turn it on. The front-panel LEDs will indicate power and status.

• Use HDMI or DisplayPort to connect your primary video source to one of the input ports (HDMI 1–3 or DP 1–2).
• For multi-source setups (e.g., Main + PIP), connect additional sources to other inputs.
• Tip: HDMI 3 supports audio pass-through if you need embedded audio monitoring.

• Connect Ethernet Port 1 (or Port 2) to your first LED receiving card using a standard Cat6 cable.
• For redundancy: Connect both Ethernet ports to form a loop between receiving cards (primary and backup paths).
• Note: The VX20 outputs video over Ethernet using Colorlight’s native protocol—compatible with RX series and most HUB75-based receiving cards.

• Connect your computer to the same network as the VX20 (via switch or direct cable).
• Open a browser and enter the VX20’s default IP (usually 192.168.1.100—check label or use DHCP discovery).
• Log in (default credentials: admin / admin).

• Go to Preconfig > Layout.
• Define your LED wall resolution (e.g., 1920×1080 pixels) and map it to the number of receiving cards.
• Assign which Ethernet port controls which section (if using dual outputs).

In the main interface, click Main, PIP1, or PIP2 to assign input sources.
Use the PVW (Preview) area to position, scale, or crop layers before taking them live.

• For critical shows: Set up a second VX20 as backup.
• In More > Advanced > Processor Redundancy, enable sync mode and link the two units via Ethernet.
• Both units will share configuration; the backup auto-takes over if the primary fails.
