4K 18Gbps HDMI 2.0 Distribution Amplifiers
About 4K HDMI 2.0 Distribution Amplifiers
VigilLink's HDMI 2.0 distribution amplifier family delivers 4K@60Hz 4:4:4 at 18Gbps to multiple displays simultaneously from a single source, with active signal regeneration at every output to maintain full resolution, HDR, and HDCP 2.3 compliance regardless of output count. Available in 1x2, 1x4, 1x8, and 1x16 output configurations — the widest output range in the VigilLink distribution amplifier lineup — this family covers everything from dual-display boardrooms to large-scale digital signage networks. The VLSP-14H20D adds an integrated 4K-to-1080p scaler for installations with mixed-resolution displays. All models carry a 6-year VigilLink warranty.
Choosing the Right HDMI 2.0 Distribution Amplifier
Standard 4K Distribution (VLSP-12H20 / VLSP-14H20 / VLSP-18H20 / VLSP-16H20): Full 4K@60Hz 18Gbps distribution in 1x2, 1x4, 1x8, and 1x16 output counts. The VLSP-12H20 suits dual-display rooms; the VLSP-14H20 covers four-screen presentation environments; the VLSP-18H20 handles eight-display signage or large-format AV systems; and the VLSP-16H20 drives up to sixteen displays from a single rack unit. Choose based on total display and destination count including any recording or streaming outputs.
With Integrated Scaler (VLSP-14H20D): The VLSP-14H20D adds a built-in 4K-to-1080p downscaler, allowing one HDMI 2.0 source to simultaneously feed four native 4K HDMI outputs and one 1080p-scaled output from a single unit. Choose the VLSP-14H20D for installations where a mix of 4K and legacy 1080p displays must be driven from the same source without adding a separate scaler or matrix switcher.
Frequently Asked Questions
What resolution and frame rate do HDMI 2.0 distribution amplifiers support?
HDMI 2.0 distribution amplifiers support up to 4K@60Hz 4:4:4 at 18Gbps bandwidth, with full HDR10, Dolby Vision, HLG, and HDCP 2.3 passthrough. They do not support 8K, 4K@120Hz, VRR, or ALLM — those require HDMI 2.1. For sources limited to 4K@60Hz maximum, HDMI 2.0 amplifiers deliver full signal quality at a lower cost than HDMI 2.1 models.
Can I use a 1x16 distribution amplifier to drive a video wall?
The VLSP-16H20 distributes one HDMI 2.0 source to sixteen displays with identical signal on all outputs. For video wall applications where different portions of an image are displayed on each screen (tiled layout), a dedicated videowall processor is required. The VLSP-16H20 is suited to digital signage networks where the same content plays on all screens simultaneously.
Do these amplifiers support HDR and HDCP 2.3 for streaming content?
Yes. All VLSP-series HDMI 2.0 distribution amplifiers support HDCP 2.3 for 4K protected content from streaming devices, Blu-ray players, and media servers, as well as HDR10, Dolby Vision, and HLG passthrough. Each output handles its HDCP handshake independently, so a non-HDCP display on one output does not downgrade the signal on other outputs.
What does the integrated scaler on the VLSP-14H20D do?
The VLSP-14H20D includes a built-in scaler that converts the 4K@60Hz HDMI input to 1080p on a dedicated scaled output, while simultaneously passing native 4K to the remaining HDMI outputs. This allows a single 4K source to feed both native 4K displays and legacy 1080p screens without a separate scaler or secondary output device.
What is the maximum HDMI cable length per output?
Standard HDMI cable runs from VLSP-series HDMI 2.0 distribution amplifiers to displays are reliably supported to approximately 10–15 meters at 4K@60Hz using good-quality 18Gbps-rated cables. For longer distances, use an HDMI 2.0 over HDBaseT distribution amplifier (VLSP-12HT150, VLSP-14HT150, VLSP-18HT150) which extends each output to 150 meters over Cat6/6A.
