VM-4K-2X2
4K/60 2X2 Seamless Video Wall Processor
Version: V1.0.1
Introduction
Overview
The LightSpeed® VW-4K-2X features a compact enclosure, instant switching, and free scaling up to 4K@60Hz SDR and HDR. It
supports two video working modes including matrix switcher mode and video wall mode to meet different application
requirements. In matrix switcher mode, it allows four HDMI inputs to be switched to four HDMI outputs. In video wall mode, the
matrix supports a 2x2 video wall layout, which can select any input for video wall outputs, configure bezel correction, and set
image rotation. It also provides both analog and digital S/PDIF audio de-embedding for outputs 1 & 2. The product can be easily
managed and controlled, for example, through front panel buttons, IR, RS232, web UI, and TCP protocols.
Features
•Seamless switching without seeing a black screen between four HDMI inputs and outputs.
•Each HDMI input and output support video format up to 4K@60Hz SDR and HDR.
•HDCP 2.2 compliant and backward compatible.
•EDID management including EDID presets, EDID copy, and custom EDID.
•Advanced video processing capabilities:
✓Supports free scaling between 480p and 4K@60Hz.
✓Supports conversion between SDR and HDR formats.
✓Supports conversion on color space, chroma, and color bits.
✓Supports instant switching between sources so black screen transition is avoided.
✓Supports rich scaler processing modes, including auto scaler, manual scaler, and video bypass.
•Supports two video working modes:
✓Supports matrix switcher mode, which can route any input to any output.
✓Supports video wall mode (2x2 layout), and configures its output distribution, bezel correction, input selection, and
image 180° rotation (to facilitate 2x2 video wall setup using TV display) through API commands and web UI.
•Can be easily managed and controlled through front panel buttons, IR, RS232, web UI, and TCP protocols.
•Supports firmware upgrade through web UI and Micro USB port.
