    Will this allow for 4 different TV's to receive any one of the 4 inputs (xbox, cable, PS3 etc...) at the same time? For example, TV1 could be using the xbox, TV2 the cable box, TV3 the PS3 all at the same time. Just want to make sure before I purchase it, thanks.
    A shopper on Dec 9, 2016
    BEST ANSWER: I just contacted mono price about this product and they said yes four outputs at the same time
    Is there a way to turn off the beep when switching inputs? I've seen some users mention it's possible but no instructions on how.
    A shopper on Aug 8, 2017
    BEST ANSWER: The instructions are listed in the user manual. You will need to access the unit via RS232 control and check off the BEEP box.
    Does the switch support ARC?

    What are the RS-232 codes for this?
    A shopper on Dec 15, 2016
    BEST ANSWER: I just ordered this so I should get it next week so I haven't tried it yet but doing some Googling I might have found the RS232 codes.

    I cannot add a link so google this and it should give only 1 result to a PDF file: Command_codes_for_LINDY_38152

    It looks very much like the same product just branded differently, so I will try next week when I get it and respond here if they work.
    I have the 4x4 version 3.0 (Product # 5704) and I am controlling it via rs232 with my control4 system. Are the rs232 commands on this unit the same for source routing?
    A shopper on Jan 3, 2017
    BEST ANSWER: Hello, at the moment we do not have the RS-232 codes available on our website. Feel free to email our technical support team at tech@monoprice.com for further assistance in obtaining the documentation, thank you!
    Will this support 4 outputs of different resolutions or do you have to use the lowest value? For example could I have one tv at 1080P, one at 1080I, and one at 720P or will all have to be at 720P?
    A shopper on May 20, 2017
    BEST ANSWER: Thank you for your question. You can use the EDID selector on the side of the unit to select between different resolutions for the output or have the unit auto detect. When auto detecting it will select the common resolution that is supported.

    Should you use the RS232 function and have it controlled via a PC. You would be able to copy the EDID information from one of the outputs to "set" it to a selected input or all the inputs. As described in the user manual on page 16.

    Why does the product description say that displays up to two receivers at the same time.? I thought a 4x4 would play any combination ( all four )at the same time.
    New User U on Jan 6, 2017
    BEST ANSWER: Hello, thank you for your question. Yes you are correct, this 4x4 true matrix does in fact display any combination and is not limited to two displays. We apologize for any confusion
    Can I get more remote control? I would like to have a remote control in each of the room.
    Rick D on Jan 1, 2017
    BEST ANSWER: Hello, at the moment we do not sell the remote control by itself, you may use an IR learning remote if you require additional remotes for this item. Thank you for your question.
    Can this unit be rack mounted? (i.e. does it come with rack ears?
    A shopper on Dec 23, 2016
    BEST ANSWER: In short, yes it comes with 'ears'. However, the unit is only about 10 inches wide so it can't be mounted in a standard rack. Also the 'ears' mount to the unit facing downwards so that it can be screwed down to a shelf.
    It would be nice if Monoprice included dimensions of products along with the accessories that come with it.
    how far can you run an hdmi for an output?
    A shopper on May 19, 2017
    BEST ANSWER: If your buying a 4K Matrix, you should be speaking of 4K Signals.
    I wouldn't run a 4K signal over ten feet even with a 4K High Speed rated cable.
    Any longer and you should start looking into Redmere Technology 4K Cables
    Can I connect an external IR receiver for the included remote?
    New User U on Dec 7, 2016
    BEST ANSWER: Hello, thank you for your inquiry, this does indeed have an IR port so you can extend the the IR for the included remote. Thank you and I hope that helped!
    Does this unit support 1920x1200 ( for a projector)?
    Mike H on Jun 7, 2017
    BEST ANSWER: Thank you for your question. This unit would be able to support 1920x1200 resolutions just fine. I would recommend using Auto Mode for the EDID settings so that it can detect the resolution of the connected projector.
    what is maximum HDMI cable length to remote TV locations?
    Michael P on May 9, 2017
    BEST ANSWER: Thank you for your question. It would more so depend on the HDMI cable that you are using. For instance, a passive HDMI cable will be able to send a high speed signal up to 25 feet if the gauge of the cable is 22AWG. If you are looking to use longer than 25 feet, it would be recommended to use Active HDMI cable. Such as our Cabernet Ultra or Luxe Active HDMI cables.

    How do you commit changes made to the EDID settings and select the output you would like to apply them to? The manual does not provide explicit instructions on this.
    New User U on Jul 6, 2018
    Can this output 4 different inputs to 4 different outputs? Also, can it take 1 input and display it to 4 outputs?
    Curtis R on May 14, 2017
    BEST ANSWER: As for the first question, yes it can take the inputs from four different sources (we used 3 DirecTV boxes and an AppleTV) and you can select which of the outputs you want which input to feed. Moreover, it easily can let you take one input, say the AppleTV and send it to all four outputs. Hope this helps. Terry
    If I had two of these switches in the same room would the IR controls interfere with each other?
    New User U on Aug 16, 2018
    BEST ANSWER: are any sources duplicated? Can you use the local display for some sources? I have 5 displays and 7 sources. 2 displays use a local source, all others use the switch.
    Do I have to do the RS-232 stuff if I'm just using it as a 4 X 4 switch?
    A shopper on Aug 27, 2017
    BEST ANSWER: No, you do not have to use the RS-232 serial interface. That is just for when you want to control the switch via computer.
    We use one of these 4x4 switches in manual mode, just using the push-buttons on the front. Alternatively, you can use the small handheld remote control that comes with it.
    Does this product support Blu-ray playback?
    A shopper on Feb 16, 2017
    BEST ANSWER: Yes, my unit handles the Blu-ray output just fine. It also interfaces ROKU-4 4K output to a Vizio 4K display. BUT: the ROKU and display need to be direct-connected to perform the 4K setup. Once that setup has been completed, using the HDMI switch works just find.
    does this work as a video wall? e.g. 1 video source scanned across all 4 monitors in a 2x2 setup.
    A shopper on Sep 19, 2017
    BEST ANSWER: To do a 2x2 video wall you'd need this box https://www.monoprice.com/product?p_id=15783
    I would like to create a video wall. One signal to four TV’s, creating a single display. Will this allow me to do so?
    Jon V on Nov 23, 2017
    BEST ANSWER: To do a 2x2 video wall you'd need this box https://www.monoprice.com/product?p_id=15783
    Monoprice Blackbird 4x4 HDMI Seamless Switching Matrix, supporting 2x2 Video Walls, Rackmountable
    Monoprice Blackbird 4x4 HDMI Seamless Switching Matrix, supporting 2x2 Video Walls, Rackmountable
    1) Does this auto-detect and route inputs with live signal? 2) If 2 inputs are sending signal, but one gets disconnected, will all the outputs switch to the sole live input? (It would be great if they did.)
    A shopper on Jun 5, 2017
    BEST ANSWER: No it doesn't auto select for you. You have to hard select it on the panel or the remote.
    How do operate the matrix with multiple IR blasters or RS232 connections? There's only one small IR receiver bulb and one rs232 connection.

    Yes - Get this one! It is Great.
    I've actually been hoping to have the opportunity to provide a review on this 4x4 Matrix.

    I have tried 4 different HDMI switches over the past 3 years. Each of those had its own limitations. Yes, the problems are mine: trying to interface with a DVI device, having four different HDMI inputs and trying to satisfy HDCP.
    But THIS unit is worth it's weight in gold. It truly, truly works, as good as advertised and then better. If you have had problems before, this guy is your answer. You will not be disappointed.

    This is an excellent device.

    PROS: not very costly, given the functionality
    actually works, with no glitches
    the built-in EDID functionality actually WORKS
    is programmable from your computer (set EDID's, and multiple other functions)

    CONS: these are trivial cons:
    the red indicator leds are a bit too bright
    there is a 'beep' sound when changing inputs (but can be programmed to be off)
    there is an on/off physical switch, but no way to power off/on via remote
    June 24, 2016
    Good, but Lack of RS232 commands
    Good device, wish I had the RS232 controls for it

    PROS: Does a good job of allowing control of input to output

    CONS: No RS232 commands, such as how to set a manual EDID based on a device.
    Due to having multiple auto sensing devices, it keeps trying to be "smart" so I have to use an EDID override. No commands to clone or manually create an EDID leaves me unable to set an EDID that matches the audio ability of my sound system (only device that uses sound off it).

    So far this Switch is the best I have used.
    I had the 4x2 True Matrix High Speed HDMI® Powered Switch with Remote Control, 3D, and x.v.Color™ Support Product # 6415 for the past two years, but wanted more than two outputs. So I boght the Blackbird 4K 4x4. I wish I have bought this sooner. Not only do I now have the 4 ouputs, but with my previous witch I would have to hit the reset button about 40% of the time to get the switch to sync right when go to different video sources. I thought that was just what you had to deal with when it came to Matrix switches. BUT YOU DON'T. This new blackbird is awesome and so far no sync issues and has worked GREAT !

    RS232 Feature Not Supported
    There is no information provided or available for using the RS323 port! This makes the product useless for the RS232 feature.
    June 21, 2016
    good with a few minor flaws
    product works great overall and I dont think you could find anything else for even close to this price that works as well. I do wish there was a way to turn off the beeping when switching sources, and I cant seem to find the software mentioned in the manual.

    Exactly what you are looking for.
    Picked this up to have my Xbox One, PS4, Wii U and media pc all connected to a set of large LCDs in my living room. This is arguably the best product for the job as it is super easy to install and works like a charm. Easily flip devices between all my screens with a push of a button on the remote.

    I don't mind the beep it makes as I like the feedback, only downside is the blaring red lights on the device that look quite off in a very clean, open entertainment of mine.

    powerful for the price
    Powerful. other less expensive switchers had problems with speed and getting the hdmi sources to recognize the tv to produce and image. this one, a button press and a second later your image appears. found a great deal thru monoprice. worth the $140 asking price but a steal at $105.

    Great product.
    It works great. I really like the adjustable booster. My friend got the older one that was not adjustable and after a storm it stopped working. Once they replaced the cable it works great again. Too many problems with the wireless HDMI, so we chose this one.

    Great HDMI Switch!
    Upgraded our old 4x2 switcher. This thing is amazing, the active matrix works perfectly and the switch time is around 1 second. Build quality is also really solid.
