StarTech 4K7012IC-EXTEND-HDMI 2-Port HDMI Extender and Splitter over Cat6
Overview
The StarTech 4K7012IC-EXTEND-HDMI is a 1x2 HDMI extender and splitter that pushes 4K 60Hz video to two displays simultaneously over standard Cat6 UTP cabling — reaching up to 230ft (70m) per run. If you're distributing a single 4K source to two remote screens across a conference room, lobby, control room, or digital signage installation, this unit handles the signal extension and splitting in one box, eliminating the need for separate splitter and extender hardware. The 4K7012IC-EXTEND-HDMI (often searched as 4K7012IC EXTEND HDMI) is sized for permanent installation: at 6.1 x 2.8 x 0.9 inches and 9.2 oz, it mounts cleanly in AV racks, behind displays, or inside equipment closets without consuming excessive space.
Key Features
- 4K 60Hz over 230ft: Full 4K resolution at 60Hz is maintained across both outputs at the full 70m run length — no resolution downgrade or frame-rate compromise at distance. This matters when your source is a 4K media player, PC, or presentation system feeding large-format displays that would visibly show a resolution step-down.
- 1x2 Splitting: One HDMI source feeds two independent Cat6 runs simultaneously, so both remote displays receive an identical, synchronized signal. This removes the need for a dedicated HDMI distribution amplifier upstream — the splitting is built into the transmitter unit.
- Cat6 UTP Cabling: Using standard unshielded Cat6 rather than HDMI cable means you're running cable that's cheaper per foot, easier to pull through conduit, and already present in most commercial buildings. A 230ft HDMI cable run is impractical and expensive; a Cat6 run to the same endpoint is routine infrastructure work.
- 2-Channel Audio: Stereo audio is carried alongside the video signal over the same Cat6 run — no separate audio cabling required to the remote displays. Useful for presentation environments where you need synchronized audio at the remote screen without running additional infrastructure.
- 12V DC / 2.0A Power Supply Included: The unit ships with a 12V DC, 2.0A power supply. Total system power consumption is 24W, which is modest for an active extender at this resolution and distance. The input draws 0.8A, so standard commercial outlets handle it without a dedicated circuit.
- Operating Temperature 0°C to 50°C: Rated for standard commercial indoor environments — conference rooms, lobbies, control centers, and equipment closets within that range. Storage temperature extends to -10°C to 70°C, so shipping and warehousing in non-climate-controlled environments won't damage the unit.
- Humidity tolerance 5%–90% RH: Covers the full range of typical commercial interior environments, including spaces near HVAC equipment or in regions with high ambient humidity. This isn't an outdoor-rated device, but it won't fail in a slightly humid server closet.
- Compact form factor: At 154 x 70 x 23mm and 261g, the transmitter/receiver units fit in tight installations — behind flat-panel mounts, inside lecterns, or surface-mounted near equipment racks without requiring a full rack shelf.
Integration and Compatibility
The 4K7012IC-EXTEND-HDMI works with any HDMI source capable of 4K 60Hz output — including PCs, Blu-ray players, media streamers, video processors, and presentation switchers. The Cat6 runs terminate at the receiver units, which output standard HDMI to the connected displays. No proprietary cabling or specialized patch panels are required; standard Cat6 UTP with RJ-45 terminations is all that's needed between transmitter and receivers. For AV integrators and IT architects planning multi-display installations, this unit fits cleanly into signal chains that already rely on structured cabling infrastructure. Note that the maximum extension distance of 70m applies to AV extension accessories using Cat6 — upgrading to Cat6A or Cat7 does not extend the rated distance beyond what the unit is specified for. Plan your cable runs accordingly during pre-installation surveys. For larger distribution requirements beyond two outputs, pair this with a compatible HDMI distribution solution upstream. If your deployment includes surveillance or digital signage tied to a broader AV architecture, review the video distribution category for complementary signal management hardware. A StarTech AV and networking catalog provides additional compatible accessories and cabling.
Frequently Asked Questions
Q: What is the maximum extension distance supported by the 4K7012IC-EXTEND-HDMI?
A: The 4K7012IC-EXTEND-HDMI supports a maximum extension distance of 230ft (70m) over Cat6 UTP cabling while maintaining 4K 60Hz resolution on both outputs.
Q: Does this unit require shielded Cat6 (STP) cable, or will standard unshielded Cat6 (UTP) work?
A: Standard Cat6 UTP is the specified cabling type. Shielded cabling is not required, which simplifies installation in most commercial environments where UTP infrastructure is already in place.
Q: Can the 4K7012IC-EXTEND-HDMI run two displays at different distances, or must both runs be the same length?
A: The unit supports two independent Cat6 runs up to 70m each. The runs do not need to be equal in length — each output operates independently up to the maximum rated distance.
Q: Does the unit carry audio over the Cat6 runs?
A: Yes. The 4K7012IC-EXTEND-HDMI supports 2-channel stereo audio transmitted over the same Cat6 run as the video signal — no separate audio cabling is needed to the remote displays.
Q: What power supply does the unit use, and is it included?
A: The unit operates at 12V DC with a 2.0A output requirement. A 12V DC power supply is included. Total system power consumption is 24W.
Q: What is the warranty on the 4K7012IC-EXTEND-HDMI?
A: StarTech covers the 4K7012IC-EXTEND-HDMI with a 2-year manufacturer warranty.

The spec that defines the practical value of the 4K7012IC-EXTEND-HDMI is straightforward: 70m over Cat6 UTP at full 4K 60Hz, with both outputs active simultaneously. In most commercial AV and presentation infrastructure projects, HDMI cable runs beyond 15-20ft become a liability — signal integrity issues, cable management problems, and cost. The 4K7012IC-EXTEND-HDMI replaces that with a Cat6 run, which is already the backbone of commercial building infrastructure.
Technical Highlights:
- 70m Cat6 reach at 4K 60Hz: Full 3840x2160 at 60Hz maintained across both outputs at the maximum 70m distance — no resolution fallback mode at distance, which matters when downstream displays are 4K panels where a 1080p fallback is immediately visible.
- 24W total system consumption: At 24W total draw with a 12V/2.0A included supply, this unit won't require a dedicated power circuit or UPS upsize in a typical AV rack — relevant when budgeting electrical load for multi-unit installations.
- 2-channel audio over Cat6: Stereo audio rides the same Cat6 infrastructure as the video signal, eliminating a second cabling run to each remote display. In a twin-screen lobby or conference presentation setup, that's real installation time saved per endpoint.
Deployment Considerations:
- Operating temperature is rated 0°C to 50°C — this is a commercial interior device. Don't spec it for equipment closets that routinely exceed 50°C under load without supplemental cooling; verify the thermal environment before installation.
- The 70m distance is the rated maximum for Cat6 UTP. Cable quality matters — installations using substandard or degraded Cat6 runs may see signal issues before hitting the rated limit. Verify cable continuity and category compliance before commissioning.
The 4K7012IC-EXTEND-HDMI is the right call for fixed installations distributing a single 4K source to two remote displays across distances where HDMI direct cable runs are impractical — conference centers, dual-screen lobby digital signage, and control room secondary monitoring positions where Cat6 infrastructure is already in the walls.
