About HDBaseT 3.0 Extenders
VigilLink's HDBaseT 3.0 extender family extends HDMI signals over a single Cat6 cable at the highest bandwidth tier currently available in the HDBaseT standard — 40Gbps for 8K HDMI 2.1 on the VLEX-HT3200U-TR and 18Gbps for 4K@60Hz 4:4:4 HDMI 2.0 with eARC on the VLEX-HT3100U-TR and VLEX-HT3100U0-TR. Models in this family also include a USB-C source input (VLEX-HT3070CU) and a compact 40-meter USB model for shorter AV deployments (VLEX-HT3040U). Every unit carries HDMI video, USB, IR control, RS-232, and PoE over the same Cat6 run — eliminating separate cable pulls for video, control, and power. All VLEX-HT3-series extenders ship with a 6-year VigilLink warranty.
Choosing the Right HDBaseT 3.0 Extender
8K HDMI 2.1 (VLEX-HT3200U-TR): Extends 8K HDMI 2.1 at up to 40Gbps to 100 meters over Cat6/6A. Choose this model when the source or display is HDMI 2.1 capable — 8K monitors, high-frame-rate workstations, or next-generation gaming and broadcast systems. This is the only HDBaseT model in the range that accommodates HDMI 2.1 bandwidth.
4K@60Hz 4:4:4 HDMI 2.0 with eARC — 100m (VLEX-HT3100U-TR / VLEX-HT3100U0-TR): Extends full 18Gbps 4K@60Hz HDMI 2.0 with eARC return channel at 100 meters. Both models carry USB and IR. The VLEX-HT3100U-TR and VLEX-HT3100U0-TR differ in front-panel layout and connector configuration — review datasheets for your installation's mechanical requirements. Choose when eARC return audio from the display (Dolby Atmos, DTS:X) to an AV receiver is required.
4K@60Hz with USB-C Input — 70m (VLEX-HT3070CU): Extends 4K@60Hz 4:4:4 HDMI 2.0 with a USB-C source input and USB 2.0 over Cat6 at 70 meters. Choose in presentation and education environments where laptop users connect via USB-C rather than HDMI.
Compact USB — 40m (VLEX-HT3040U): A shorter-reach HDBaseT 3.0 model for 4K@60Hz 4:4:4 installations up to 40 meters with USB included. Choose for medium-distance boardrooms and classrooms where full 100-meter reach is not needed.
Frequently Asked Questions
What makes HDBaseT 3.0 different from HDBaseT 2.0?
HDBaseT 3.0 increases maximum bandwidth from 18Gbps to 40Gbps, enabling 8K HDMI 2.1 transmission and adding eARC audio return channel support. HDBaseT 2.0 is limited to 18Gbps (4K@60Hz HDMI 2.0) and does not support eARC. HDBaseT 3.0 extenders are backward compatible with 4K@60Hz HDMI 2.0 sources and displays.
Do HDBaseT 3.0 extenders support eARC and how does it work?
Yes. The VLEX-HT3100U-TR and VLEX-HT3100U0-TR support eARC (Enhanced Audio Return Channel), which carries Dolby Atmos and DTS:X audio from the display back to an AV receiver over the same Cat6 cable used for HDMI video — eliminating a separate optical or HDMI ARC cable. eARC requires a compatible display and AV receiver.
What Cat cable specification is required for HDBaseT 3.0?
HDBaseT 3.0 requires Cat6 or Cat6A cable for reliable performance at rated distances. Cat5e may work at shorter distances but is not recommended for 100-meter or 8K deployments. Use shielded Cat6A (STP/SFTP) in environments with significant EMI or near power cables.
What is the VLEX-HT3070CU USB-C input used for?
The USB-C input on the VLEX-HT3070CU allows a laptop or device with USB-C (Alt Mode DisplayPort/HDMI) output to connect directly to the transmitter without a separate HDMI adapter. The unit converts the USB-C signal to HDMI 2.0 and extends it over HDBaseT 3.0 to the remote display. USB 2.0 is also carried over the same Cat6 link.
Can HDBaseT 3.0 extenders power the receiver using PoE?
Yes. HDBaseT-series extenders carry PoE (Power over Ethernet) over the Cat6 link, allowing the receiver to draw power from the transmitter rather than requiring a separate local power supply at the display end. Confirm per-model PoE specifications in the product datasheet.
