HDMI & AV Extenders — 4K 60Hz Over Cat6, Up to 328ft
Extend HDMI, DVI, and VGA signals beyond standard cable limits using Cat5e/Cat6. Conversions Tech extenders support 4K 60Hz HDR, HDCP 2.2, bidirectional IR, RS-232 control, and Power over Cable for single-cable installations.

| HDBaseT 70m | HDMI 2.0 | 230ft (70m) | 4K 60Hz | HDR, PoC, IR, RS-232 |
| HDBaseT 100m | HDMI 2.0 | 328ft (100m) | 4K 60Hz | HDCP 2.2, Ethernet, bidirectional IR/RS-232 |
| DVI over Cat5e | DVI | 300ft (100m) | 1080p | Legacy DVI extension |
| VGA 4-way over Cat5 | VGA | 900ft (275m) | 1080p | 4-way split + extend |
Why use an extender instead of a long HDMI cable?
HDMI cables degrade beyond 15-25 feet at 4K. Active HDMI cables max out at ~75 feet and cost more than an extender setup. Our HDBaseT extenders send 4K 60Hz over inexpensive Cat6 up to 328 feet with zero latency, plus IR and RS-232 control — something no HDMI cable can do at any length.
Common applications
- Conference rooms: Laptop at the table, display on the wall, 50-100ft apart
- Houses of worship: Camera/switcher in booth, displays in sanctuary and overflow
- Retail / digital signage: Media player in back office, displays on sales floor
- Education: Instructor PC to projector across a lecture hall
- Residential: Media closet to TV in another room through existing Cat5e
Need to split AND extend? See our HDMI splitter-extenders that combine both functions. For cables, see HDMI cables and Cat6 patch cables.

Audio-Video Extenders FAQ
1. What is an A/V extender?
A/V extenders transmit HDMI, DisplayPort, audio, USB or control signals over longer distances than standard cables—typically via Cat 6/6a, fiber, or coax—while preserving resolution and latency.
2. How far can Conversions Tech HDMI-over-Cat 6 extenders run?
Up to 150 m / 492 ft at 1080p and 70 m / 230 ft at 4K60 4:4:4 using solid-copper Cat 6a; HDBaseT models reach 100 m at 4K.
3. Do they support 4K60 HDR?
Yes—our latest HDBaseT 3.0 and 18 Gb/s HDMI 2.0 models pass 4K60 4:4:4 HDR10/HLG and Dolby Vision.
4. What cable should I use?
Solid copper Cat 6a/7 for twisted-pair units; OM3/OM4 duplex multimode fiber for 10 Gb/s optical extenders.
5. Is there any noticeable latency?
All copper extenders are visually lossless with <1 µs latency; fiber models are essentially zero-latency (no compression).
6. Do they carry USB for webcams or touch screens?
Yes—select SKUs include integrated USB 2.0/USB-HID channels (up to 60 m) for KVM, interactive displays, or PTZ camera control.
7. Are extenders Power-over-Cable capable?
PoC/PoH units send 48 V DC from either the TX or RX so you only need one PSU at the source side.
8. Do they pass EDID, HDCP 2.2 and CEC?
Absolutely—bidirectional EDID & HDCP 2.2 authentication plus one-way or two-way CEC depending on model.
9. Is IR or RS-232 control included?
Most models feature 20–60 kHz IR pass-through and full-duplex RS-232 (up to 115 kb/s) for projector lifts or matrix switchers.
10. Can I cascade or daisy-chain extenders?
You may add a switcher or splitter between hops, but signal regeneration adds cost. For >100 m consider our fiber series.
11. Wall-plate vs. box style—pros and cons?
Wall-plates blend into conference rooms and draw PoH locally; standalone boxes suit rack-mount installs and offer more I/O (USB, audio).
12. Do extenders support ARC/eARC?
Yes—HDMI 2.1 eARC is available on the 48 Gb/s fiber units; copper HDBaseT supports ARC (audio return) up to Dolby Digital 5.1.
13. What ESD & surge protection is built in?
±8 kV contact / ±15 kV air ESD plus 2 kV lightning surge on TMDS, per IEC 61000-4-5.
14. Rack-mount options?
1U and 2U rack trays hold up to eight transmitter or receiver boxes with front-mount power distribution.
15. Installation tips for best signal?
Keep Cat cables away from AC mains, punch down keystone jacks instead of RJ-45 couplers, and use factory-terminated Cat 6a for 4K60.
16. Are these extenders HDCP-compliant?
Yes—versions up to HDCP 2.3 with automatic key renewal for 4K UHD Blu-ray and streaming devices.
17. Warranty & tech support?
3-year advance-replacement warranty plus lifetime e-mail/phone support.
18. Where can I download spec sheets & manuals?
