HDMI 2.0 repeater for 4K 60Hz runs

Extends an HDMI 2.0 signal up to 45 ft while keeping 4K resolution at 60 Hz. Designed for installers and home-theatre owners who need a longer run than a passive cable allows. The inline booster sits between two certified HDMI cables and adds amplification without adding latency. It also passes 7.1 surround sound and HDCP 2.2 for protected content.

Check cable length and power source first

Verify that each HDMI cable run stays within certified limits so the repeater only bridges the gap. The unit draws under 2.5 W from a USB Micro-B port; a standard USB charger or powered port is sufficient for most installations. If the source device already drives the full distance, the booster is unnecessary and will not improve the image.

Fits between two HDMI cables near the display

Connect the source to the female HDMI input, then run a second cable from the female output to the screen. The 30 cm Micro-USB power lead reaches a nearby USB port or wall adapter, leaving the repeater body easy to hide behind equipment. It frees the installer from distance limits without requiring an external power brick or active optical cable.

Questions about this item

Does the box include the two HDMI cables I need to reach 45 ft, or must I buy them separately?

The package contains the booster, a 30 cm Micro USB power cable and a quick-start guide; you supply two certified HDMI cables for the full 45 ft run.

My source is only 1080p — will the HDBOOST4K2 still work, or do I need a 4K source to use it?

The extender is backward compatible with 1080p and lower resolutions, so a 4K source is not required.

The spec says 18 Gbps bandwidth — what does that actually let me send over a 45 ft link?

It carries 4K at 60 Hz with 7.1 surround sound and HDCP 2.2, matching the full HDMI 2.0 data rate over the extended distance.
