LightWare DA4-HDMI20-C 1 input 4 output HDMI 2.0 distribution amplifier with EDID Management and Pixel Accurate Reclocking

Product Overview

The Lightware DA4-HDMI20-C is a 1-input, 4-output HDMI 2.0 distribution amplifier engineered for professional AV installations where signal integrity and display synchronization are non-negotiable. With Pixel Accurate Reclocking on every output and full EDID management, this unit delivers a stable, identical 4K signal to four displays simultaneously — without the signal degradation common in passive splitters or lower-tier active solutions.

Product Description

The DA4-HDMI20-C supports HDMI 2.0 at 18 Gbps bandwidth, accommodating 4K/60Hz at 4:4:4 chroma, HDR10, Dolby Vision, and HDCP 2.2. Pixel Accurate Reclocking regenerates a clean clock on each output port, eliminating jitter artifacts that appear when driving long cable runs or marginal displays. The integrated EDID management system lets integrators store, emulate, and assign custom EDID profiles — critical for ensuring source devices output at the correct resolution regardless of which displays are connected downstream.

The unit ships in a compact 1U half-rack form factor suitable for equipment racks, AV furniture, or wall-mount enclosures. Power is supplied via an included IEC cable. Available from Creation Networks.

Frequently Asked Questions

Does the DA4-HDMI20-C support 4K HDR content?

Yes. It passes HDR10 and Dolby Vision metadata intact on all four outputs, provided the displays connected downstream support those HDR formats.

What does Pixel Accurate Reclocking do?

Reclocking regenerates the TMDS clock on each output, eliminating accumulated jitter from long cable runs or source devices with marginal signal quality. This prevents image artifacts such as sparkling, noise, or intermittent dropouts on displays.

Can I use different EDID profiles for different outputs?

Yes. The EDID management system allows you to assign independent EDID profiles per output port. This is useful when the four connected displays have different native resolutions or capability sets.

What cable length can I run from each output?

With standard 28 AWG passive HDMI cables, reliable 4K/60Hz operation is typically achievable up to 5–7 meters. For longer runs, use 24 AWG cables, active HDMI cables, or HDMI fiber extenders.

Is the DA4-HDMI20-C compatible with control systems?

Yes. It integrates with Lightware Device Controller software and supports RS-232 and Ethernet control, making it compatible with third-party control systems including Crestron and AMX.

Does it support audio pass-through?

Yes. All audio formats carried within the HDMI 2.0 signal — including Dolby Atmos and DTS:X — are passed through to all four outputs without modification.
