    Does this device bypass HDCP? If not, the above diagram will not work.
    Brad K on Mar 21, 2017
    BEST ANSWER: It does not bypass HDCP.
    Does this come with a 5v power cord or is that a separate item?
    A shopper on Jan 11, 2018
    BEST ANSWER: Not included. It isn't necessary unless you are trying to troubleshoot signal issues or are using Active HDMI cables.
    Will this splitter work with a Direct TV standard HD receiver with 1 HDMI output to feed 4 HD TV's? The splitter will be installed in a RV.
    A shopper on Mar 21, 2017
    BEST ANSWER: Thank you for your question. Yes, you would be able to connect via the HDMI output of your DirecTV receiver to the 1x4 splitter to then split the signal via HDMI to the 4 HD TVs in your RV.

    May the monitors be different models?
    A shopper on Feb 19, 2018
    BEST ANSWER: I would think so, as long as they can all handle the same resolution. Your computer would see this as one monitor. This is an educated guess since I haven't tried this.
    will this display video on more than one display at once?
    Matthew C on Oct 7, 2017
    BEST ANSWER: Yes, I use this to send video from an AVR to 3 televisions. The same video will be on all the televisions.
    Can I use a cat5 balun from the cable box to this splitter?
    Rayland H on Jan 14, 2018
    BEST ANSWER: I have 3 other Monoprice splitters in use with Ethernet HDMI extenders. This model I haven't tried with an extender. I would expect that it will work. All of my extenders have CAT6 cables, the longest is 50 feet to carry a signal from my downstairs cable box to the second TV in my living room. Our cable company only has one remote frequency so two cable boxes cannot be in the same room and have both operated by remote.
    Will I work with DTV satellite box?
    A shopper on Aug 6, 2018
    BEST ANSWER: I don't see why not... the issue I ran into with is the resolutions have to be the same...
    Can I use an HDMI splitter to split the signal from a single computer and connect to two Blackbird 4K HDMI 1x8 Splitter Extenders to connect up to 14 monitors? Is this possible or would I need to have a second computer? Thanks in advanced!

    Monoprice Blackbird 4K HDMI 1x8 Splitter Extender over Cat5e and Cat6 with IR, Loop Out, EDID, POC with 8 Receivers, 50m, 164ft
    Monoprice Blackbird 4K HDMI 1x8 Splitter Extender over Cat5e and Cat6 with IR, Loop Out, EDID, POC with 8 Receivers, 50m, 164ft
    BEST ANSWER: As long as your resolutions are supported by the splitter and extenders you should be fine. I have used this to split a signal off of my ATEM switcher and send them to numerous outputs, sometimes using the single version of the Blackbird extenders.
    How far can the hdmi lines go ?
    A shopper on Nov 2, 2017
    BEST ANSWER: I have mine connected to hdmi to ethernet cables so mine is 100ft.
    Is this useful for extending a display on 3 monitors with hdmi from a laptop on a dock with an hdmi output?
    Jerry P on Jul 25, 2017
    BEST ANSWER: No, I don't think so. This unit will only duplicate the HDMI output of your computer, laptop or dock on up to 4 monitors. But it will be the" same picture" If you want an extra wide display stretched across 3 monitors, or want to display 3 different screens with each of the 3 extra monitors, you would need a graphics expansion unit , like a Matrox TripleHead2Go unit.
    does this HDMI switch support audio to all channel same time?
    A shopper on Mar 22, 2017
    BEST ANSWER: Thank you for your question. This unit would be an HDMI splitter. Which will send one video/audio signal via HDMI to 4 TV's via HDMI.

    An HDMI switch will allow you to connect multiple devices such as a bluray player, cable box and gaming console to one HDMI port on the TV. You would only be able to use one at a time though.

    Regardless of using a switch or splitter HDMI will carry the video and audio. So in a splitter, it will send audio and video at the same time to all the ports. I hope this helps.
    HDCP Version 1.4
    I did not think that would work with any 4K copyrighted (movies) media, does it?
    A shopper on Mar 21, 2017
    BEST ANSWER: Thank you for your question. HDCP 1.4 will work for 4K copyrighted media. However, if your source device/ TV require the updated HDCP 2.2 for 4K media then HDCP 1.4 would not work to display 4K content. I would recommend verifying if your source and display will still support 4K with HDCP 1.4. I hope this helps.
    Will this work on TVs with less resolution that 1080p such as 720?
    Matt S on Mar 21, 2017
    BEST ANSWER: Absolutely. If you have fewer than four devices, you want to ensure that you have output device number one hooked up because I believe it routes the EDID calls to that device based on the fact that it must be plugged in before the output device can sense what resolutions are possible. This device will not handle 4K at 60Hz or any other advanced HDMI 2.0 stuff like HDR. But it works fine for 1080p60, 720p60, and other "normal" high definition formats.
    Will it support 4 50 feet HDMI cables?

    Does this support Swann HD security camera systems?

    Wise choice
    Two months ago I purchased this as a trial unit and have used it 24x7. It has worked flawlessly with all outputs in use. This means that the power supply is adequate. I am placing order for more units for my professional installation.

    Worked exactly as described!
    After reading the reviews on splitters from various vendors, I was not sure which one to order because the descriptions were very confusing. The description on Monoprice was very clear and sounded exactly what I was looking for. When it arrived, I hooked it up as indicated and it worked very well.

    Pretty good for the price.
    Nice and small, and a great price. Seems to work quite well.
    Using it to split a satellite receiver output between the living room, and the kitchen tv, around the corner. The only minus so far, is when you power on the kitchen tv, the living room tv blanks out for a few seconds, then comes back on.
    Annoying, but for the price, it's not a show-stopper.

    Splitter works well
    I was surprised that the splitter uses a small power brick and has a white "on" light that shows up if you're sleeping on the couch - I guess I didn't read the description when I bought it! There's a slight pause in video and sound when you switch off or non one of the devices plugged into it while watching another. But it works well. I don't notice any deterioration in sound or video quality.

    Great product for the price
    I ran a cat 5 balun from the cable box (35 ft) to the splitter. Then I ran another balun back to the tv where the cable box was and I fed 3 hdmi cables (4ft, 6 ft, & 10 ft) to 3 other TVs and everything worked awesome for the entire super bowl party. Great product for the price

    Blackbird 4k Mini 1x4
    The device worked great until I added the third output cable.
    there was not enough power so it shut off (the third device was connected to a heavy duty cable . I purchased the next size up and so far so good. I plan to return the mini soon.
