4K 120Hz HDMI Extender Over Single Cat6A/7 - Long-Range 4K 120Hz

Our review of this HDMI extender focuses on users who need to push high-refresh 4K signals beyond the length limits of a standard HDMI cable. The unit is suited to gamers, PC users and home theater installers who want 4K@120Hz over a single CAT 6A/7 run up to 120ft, and it delivers that capability for setups that support HDMI 2.0 class signaling and HDR. The biggest reason to consider it is the combination of high frame-rate 4:4:4 video at long distance and handy features like bi-directional IR and an EDID toggle for source compatibility.

Key Features

• 4K@120Hz 4:4:4: Lets compatible PCs and consoles output high-refresh 4K video up to 120ft over a single Cat6A or Cat7 cable for smoother motion and reduced input lag at distance.
• HDCP 2.3 compliant: Supports modern content protection while remaining backwards compatible with older HDCP versions to maximize source and display compatibility.
• HDR support: Passes HDR metadata to deliver an expanded color range and improved contrast on HDR-capable displays.
• Bi-directional IR: Enables remote control of the source from the display end or vice versa, useful when equipment racks are remote from seating positions.
• EDID toggle control: Provides a simple switch between STD mode for 4K 120Hz and a TV mode that passes EDID to the display to resolve handshake issues with some TVs.
• Digital audio formats: Passes common compressed and lossless audio formats including LPCM, Dolby Digital and DTS variants for full AV system integration.

Who It's For

The extender is ideal for gamers and PC users who need true 4K 120Hz at a distance from their source device, or integrators running a single Cat6A/7 cable between rooms, living spaces and AV racks. It also fits home theater owners who want HDR and modern HDCP support while retaining audio format compatibility for surround receivers.

Those who should look elsewhere include owners of specific displays that are not compatible with 4K 120Hz over this extender (for example certain monitors) and users who need passive long-run solutions without any EDID or IR control; testing with your exact source and display is advised to confirm full compatibility.
