    4K 60Hz Wireless HDMI Extender - The new standard in 2018

    J-Tech Digital is excited to introduce their brand new 4K 60Hz wireless HDMI extender. This new extender (model #JTECH-WEX-4K60) works just like our previous J-Tech Digital HDMI extenders, and still makes use of the HDBitT protocol.

    What is HDBitT?

    HDBitT, short for High-Definition Digital bit transmission Technology, is a protocol that enables high definition audio and video to be transmitted through a variety of different mediums. These mediums include: network cable, optic fiber, power line cable, and even wirelessly through WiFi. HDBitT provides improved stability, better image quality, greater transmission distance and other significant advantages.

    What separates the new JTECH-WEX-4K60 wireless HDMI extender from our current product line is that this new wireless extender can transmit a Full UHD 4K resolution signal at 60Hz. In order for a device to display this high definition resolution, it will have to be compliant with the most current form of content protection. This form of content protection is known as HDCP, and the most current generation of HDCP is HDCP 2.2.

    What is HDCP?

    HDCP stands for High-bandwidth Digital Content Protection, and is a form of digital copy protection. This protection was developed to prevent copying of digital, audio & video content as it travels across connections, such as HDMI or DVI. HDCP 2.2 is the next generation of copy protection for the 4K era, meaning that any device that is not HDCP 2.2 compliant will not be able to produce or display true 4K content.

    What is "true" 4K?

    Many HDMI extenders are able to display 4K resolutions, (3840 pixels horizontally by 2160 pixels vertically), without being HDCP 2.2 compliant, but only at 30Hz, or frames per second. Now, one crucial factor in quality of an image is the refresh rate. In order to experience the most high definition image available on your TV, your ideal refresh rate should be 60Hz, not 30. A 4K resolution with a refresh rate of 60Hz is known as "true 4K", whereas 4K at 30Hz is simply an imitation, with a noticeable difference in quality.

    What is refresh rate?

    Refresh rate is how often a TV changes the image (also known as a "frame") on screen. With traditional televisions, this is 60 times each second, or "60Hz", however for different formats and mediums of video, you may see refresh rates of 24, 25, 30, and more. The standard for TV is currently 60, but whether it is a standard definition 1080P TV, or high definition 4K, the best quality image will still be the display with the highest refresh rate. The JTECH-WEX-4K60 is HDCP 2.2 compliant, and therefore is able to product an Ultra HD video resolution.

     Why choose our Wireless Extender?

    While there are other companies and manufacturers that offer wireless HDMI extenders, very few of them will be full Ultra HD extenders, as most competing extenders only support 4K at 30Hz. Thanks to the UHD 4K resolution at 60Hz, you will experience a much smoother and more fluid image with our wireless extender.

    HDMI Wireless Transmitter Comparison - Wireless HDMI Extender HDMI Wireless Transmitter Comparison

    Just like our previous versions of wireless HDMI extenders, you will still get the same transmission distance range of 660 feet (200m). This transmission distance will allow you to send a signal from your source device to your display over great distances, go through walls, and still be able to control your source via the IR extension cables that come included. Adding to the seemingly endless list of features, this device is also a one-input to two-output extender. This will allow you to connect an additional receiver, to transmit to 2 HDMI displays.

    We guarantee that this product is like no other available on the market, and you will find that other companies do not offer anything with as many features as ours. Some companies sell single extenders, or extenders that only display 4K at 30Hz, and at a much shorter distance. Only with J-Tech Digital do you get so many amazing features in 1 device. For a demonstration on how the unit works and how it is set up, watch this brief video of our previous wireless HDMI extender:

  • Audio Settings for J-Tech Digital HDMI Extractor

    J-Tech Digital ® Premium Quality Hdmi To Hdmi + Audio (Spdif + RCA Stereo) Audio Extractor Converter is our best seller product. It can extract digital audio signal from the HDMI input and convert it to 2 channel analog stereo output or 5.1 channel Audio output.
    To improve our customers using experience, we just post three tips when you are using this product.

    1.Switch EDID Button
    When you can’t get the sound, the first thing you can try is switch the EDID audio switch in the front. Change it between 2CH, 5CH or pass.

    2.Turn Off Dolby Digital Plus
    Because TOSLINK (spdif) does not support Dolby Digital Plus, we need to turn off Dolby Digital Plus function of the input device. Then the sound can go through our extractor. Here are samples for how to turn Dolby Digital Plus off.

    • Amazon Fire TV

    Settings  --> Display&Sound --> Audio --> Dolby Digital Output --> Dolby Digital Plus off


    • Apple TV

    Settings --> Audio&Video --> Dolby Digital --> Off


    • Amazon Fire TV Stick

    Settings  --> Display&Sound --> Audio --> Dolby Digital Output --> Dolby Digital Plus off


    • Roku and Chromecast

    When you are playing Dolby Digital Plus content on those two devices there is no option that you can shut down Dolby Digital Plus. So you can’t get sound from spdif or RCA port.

    3. Audio through HDMI

    When the incoming HDMI audio format is Dolby Digital Plus, PCM 5.1CH, PMC7.1CH, Dolby TrueHD or DTS-HD Master Audio, both the SPDIF and L/R outputs will not work, but you can still obtain these advanced audio signals from HDMI output, because HDMI output signal is identical to the HDMI input signal.
