    HDMI® Equalizer Extender Repeater (3.4Gbps) - Extend Upto 114FT

    Extend the distance you can run High Speed HDMI® cables with full 1080p support to up to 35 meters with this HDMI repeater!

    The adjustable equalizer allows you to tune the performance of the repeater to your specific situation and cable lengths. It will also help reduce the presence of digital noise (aka "sparkles") in the video for a clean and clear picture.

    The repeater is compatible with the HDMI 1.3b standard and supports full HDCP pass-through, so you won't have any handshake or copy-protection problems. It supports 12-bit per channel (36-bit total) deep color and high resolution audio, including DTS® Digital, DTS-HD Master Audio™, and Dolby True-HD™.

    In most cases the repeater draws its operating power from the HDMI cable itself. Only when the input signal is too weak and the voltage falls below 4.75 volts will an optional AC adapter power supply (not included) be required for use. The optional power supply can be any standard 5 VDC, 2A, power adapter with a 5.5 mm outer cylinder size and a 2.5 mm pin size.

    A pair of "L" shaped brackets with mounting screws are included, so you can fix this repeater to a flat surface. Above each HDMI connector is anchor nut, allowing you to screw in a locking bracket to keep the HDMI connector from coming loose. The HDMI connectors are gold-plated to ensure maximum signal quality.

    The repeater is RoHS compliant. It is UL listed, and is FCC and CE certified.

    For installation, the repeater should be placed as close as possible to the destination device (TV). There is no set standard for adjusting the EQ switch because each situation and each piece of equipment varies. Start with the default 0 setting then try increasing the amount of EQ one click at a time until a clean and reliable signal is seen on the TV.


    • Supports up to 1080p resolution
    • Supports 225 MHz/2.25 Gbps per channel (6.75 Gbps all channel) bandwidth
    • Supports 12-bt per channel (36-bit all channel) deep color
    • HDCP pass-through
    • Iron Shell for better EMI elimination
    • Supports uncompressed audio, such as LPCM
    • Supports compressed audio, such as DTS® Digital, Dolby® Digital (including DTS-HD Master Audio and Dolby True-HD)
    • 8 levels of equalization settable by turning the EQ switch from 0 to 7

    Please note that whenever any device, such as this repeater or an AV receiver, is inserted between the source and destination devices, Monoprice strongly recommends the use of minimum 24 AWG cables, even for short runs. For cable runs longer than 15 feet, 22 AWG cables are strongly recommended for best results, especially with 1080p signals.

    Works with Power Adapter

    • That Dude Rob,

    Pros: Now I can run 50ft of HDMI cable from my early 2011 Macbook Pro

    Cons: not without a power adapter though.

    Running Serato ScratchLive and Serato Video from an early 2011 MacBook Pro. When I connected a tunderbolt to HDMI and a 50ft HDMI cable I got no signal for the video output. 25ft HDMI works fine.

    So, I tried this adapter for the 50 ft cable. Didn't get any video until I connected a power adapter. Luckily I had one from my Intellivision Flashback classic game console that was the same kind I needed.

    Doesn't work : (

    Pros: None that I have been able to see

    Cons: It doesn't work and in fact made the problem worse

    I plugged this in with the hope that it could boost the high speed HDMI 3D signal I need for my new projector going through a 25 ft Monoprice cable. Not only did it not help at all but the ability of the projector to communicate with my smart Yamaha amp went away because it no longer turned the TV video off like it did before. I know the projector works because I've used shorter cables and a straight run into the projector with the 25 ft cable and it works fine. My next option is to try to return/replace this unit (hoping it's just defective) or skip it and go to a Redmere cable but that type of cable is one way so it won't have any "smart" functions.

    Hello bbqstan,

    Thank you for your review and truly sorry to hear about the issues experienced with PID 8120. If I may ask, do you have the repeater closer to the source or the projector? For best performance, we recommend placing the repeater close to the projector. Have you tried adjusting the EQ dial setting? What about testing the repeater with a different source or display just to further isolate what the issue may be? Please let me know so we can look into this issue further. Thank you!

    Also, please note that Redmere cables are only directional in regards to power. They draw power from the end labeled as "TV" in order to work so the "TV" end must be plugged into the display device. Smart functions as well as Audio Return Channel will still work with Redmere cables. Hope this helps!

    It worked very well.

    • SHinPW,

    Pros: It cleaned up the signal.

    Cons: None

    I attached it near the destination device (an AV receiver), saw that red LED power indicators on both sides of the HDMI Extender were lit (implying that the device was receiving power from both the source and destination devices), set the rotary equalization switch to each of the 8 options to determine which options would work (3 options worked), and selected the middle of the three working options. There was no need for a power supply. The total length of the set of HDMI cables between the source device and the HDMI Extender was on the order of 50'. How many cables, you ask? Six. Three of them are embedded in walls. The other three connect the in-wall segments and termination devices together. This was simple and effective solution. Hope it will last. Expect that it will.

    Worked perfectly.

    Pros: Small, simplistic.

    Cons: Does not come with a power supply.

    I had a customer who had a HDMI run of about 35ft. The tv was showing green sparkles in place of black colors, general distortion. The adapter worked perfectly without being powered at all.

    Pros: Nice, compact metal box.

    Cons: No power supply!

    Wound up ordering this and a separate power supply from another source to try and troubleshoot a problem. So have no usable knowledge of this unit other than if you need a power supply- you won't be able to find it on the Monoprice website.
