    Can I use displayport to hdmi adapters with this?
    Steven G on Sep 11, 2017
    BEST ANSWER: Yes, generally those work with any HDMI port
    Can you buy replacement receivers for this?
    James M on Jul 18, 2017
    BEST ANSWER: We do not have replacement receiver baluns for this unit.
    Signal intermittently drops and the TV screen goes black. We used this setup flawlessly a month ago but now it is flickering. Any suggestions?
    New User U on Dec 5, 2017
    BEST ANSWER: I use 8 of these in commercial settings. The only instance of screen flickering that I have seen was the result of the power supply being pulled slight out of the unit. It was so slight that it was difficult to see. . Once I pushed it back in, the unit worked flawlessly.
    Can I use the splitter to create a video wall?
    A shopper on Jan 3, 2017
    BEST ANSWER: If you want the same image on all of your TVs, then yes. This splitter repeats the same input signal across all outputs. If you want multiple input/output configurations, you will want to purchase an HDMI matrix splitter.
    I currently have an installation with converters installed at each TV. If I purchase one of these, will it be compatible with the existing Cat5- HDMI converters on the TV end?
    A shopper on Jan 18, 2017
    BEST ANSWER: It should be compatible but I would double check to make sure your existing wire is cat5e not just cat5. I've used 4 of these setups and they work great.
    How do I get it to do anything other than 1080i?
    Claims supports 1080p but never able to use more than 1080i, Cat6 550Mhz rated Monoprice cables, any length (7' or 100')

    Thank you
    ?????Can i come out of the splitter with Ethernet plug into a home network router and then put back on the receiver
    A shopper on Mar 14, 2017
    BEST ANSWER: Thank you for your question. This unit would not work in that way. It would require the receiver to be connected directly to the transmitter. We do have our Bit-Path HDMI Extenders that will support being connected to a network via ethernet, such as PID 14158. You would then be able to add receivers to the router or an ethernet switch, such as PID 15522. Then from the receivers you can connect to the TV's.

    Hi we run 220' HDMI cable from DVR to TV with tree splitter adapters and no signal
    Some one can help in this trouble shooting ?
    A shopper on Dec 14, 2016
    BEST ANSWER: You should run 220' of Cat6 cable instead of HDMI cable. You need the 1 x 4 splitter/adapter that is featured in this review.
    Is this an hdbaset transmitter?
    Michael S on Nov 30, 2016
    BEST ANSWER: No. This just transmits the HDMI signal over twisted pair, AKA, CAT 6.
    Is there a kit to rack mount this?
    A shopper on Sep 17, 2018
    Will this splitter support a 720p tv with two 1080p displays?

    Works well but quality problems
    We installed this for a church and are running 3 TVs at 1080P - each at a distance of about 100 ft, The picture quality is generally very good although I have seem some artifact on one of the TVs. We are using solid copper CAT6 cabling for the installation.

    As mentioned above, there a couple of concerns. After a few months of (flawless) operation, we began noticing that the screens would occasionally go blank. Since we had just switched computers, the first thought was that it was the screen saver on the computer. Adjustments were made, but the next week the same thing happened even sooner. Second thought was that the transmitter was cutting out because of heat - it does run pretty hot, and as someone who makes a living as an EE, I can tell you that heat is the enemy of reliability in electronics. Then we noticed that just moving the transmitter would cause it to work/not work. The transmitter was removed and taken apart (what can I say) and found to have a very loose power connector - just tilting the transmitter caused the connector to wiggle. Upon further examination, a solder joint for the power input on the connector was broken, and appeared as though it had never been properly soldered (quality issue). After repairing the solder on the connector and pointing a small fan at the transmitter, the unit again works flawlessly and runs nice and cool.

    It appears from other reviews that there are some heat related failures - units where 1, 2, or 3 of the ports quit working. Bottom line, I would buy again, but with the requirement that there has to be some air flow over the transmitter.

    PROS: Good quality picture to 4 TVs

    Simple installation

    CONS: Transmitter runs pretty hot

    Quality issues
    November 20, 2015
    Neat product but not as reliable as hoped
    I have had this product for just over two years. It does exactly as promised and was perfect for what I needed. Feature-wise I love it.

    However after about one year, one of the four ports quit working. Now, just over two years old, a second port has quit, effectively making it useless for my purpose. For the cost, I was hoping it would last longer, and I am weary about purchasing a replacement if they are not built to last - I cannot afford to buy a new one every couple years.

    My installation was aplit to three LED TVs over 35 feet each. The signal was definitely inadequate with CAT5e but was perfect over CAT6. I would not try to use this with CAT5e.

    PROS: Works like a charm, but only with CAT6. Its signal over CAT5e over a distance of only 35 feet was degraded markedly.

    CONS: It does not work well with CAT5e, even at a distance of 35 feet

    worked great til it stopped working
    There was very little delay in the images, and all seemed to work. However, the unit died and is no longer working. I suspect it's the sender unit, unless all three of the units (we're not using the fourth one) died. In which case, both are equally as terrible in quality.

    PROS: Worked for the first week

    CONS: Like many of monoprices products, there is no quality control from China. They seem to be great for cables, but components like this that need to be kept on, they just stop working after a few weeks.

    Love it
    Works like a dream. Delivering HD video and sound to multiple TVs.
    Connected to (2) 70", (1) 32", and (1) 26" HD widescreen TVs. Input is either a laptop or DVD player. Running 100' cat6 cable and 24AWG High SPD HDMI cables. Picture and sound is perfect!

    PROS: Easy to set up. PnP. Running the cables was the hardest part of it.

    CONS: None that I run into.

    Works great, even over Cat5e!!!
    I am running the signal from a DirecTV HD receiver to two 20" TVs. One TV is about 20 feet from the splitter, the other is about 50 feet. Both runs are on Cat5e cable. The picture looks fine on both TVs. The only problem that I had was that I was using really short HDMI cables. I chatted with tech support and they recommended switching out the short cables for longer ones. I switched the cables out and works perfectly.

    PROS: Great picture
    Easy set up

    CONS: Needed some troubleshooting, but tech support got me to the solution pretty quickly.

    Works Great!
    I bought this device - system really, to distribute the output from my HTPC to 4 TV's scattered throughout my home. I use Monoprice PID : 5369 to convert DVI and toslink (optical) audio from the HTPC to the combined HDMI signal used by this device. The system works great using hardwired CAT6 jacks and cables making for a clean look behind the TVs.

    PROS: Easy to set up - Plug and Play
    Works with existing in-wall CAT6 wiring
    Works with cable boxes, DVRs, Home Theater PCs, ANY HDMI signal I was able to throw at it.

    CONS: Power must be supplied to the small converter box at each TV, with a wall wort.

    I had been using a wireless hdmi transmitter for some time, it was flakey losing signal and degraded quality the longer it stayed on. Wife was very annoyed by the displays blanking out as the HDMI handshaking took place, This switchbox solved all that, I only had to run cat 6 cable between the 2 displays. It's next to my dish network set top and main TV which is why I wish it just had and HDMI passthrough. But I took the small run of cat 6 route as another reviewer did for the closer display. If you're anal retentive about cables this may be an issue. Also when I tried using a 3 ft HDMI cable on the reciever for the 2nd display at the end of a 75 ft run of Cat 6, It did not work, having seen the previous reviewers solution of using a longer cable I tried that and it work. Once again, not ideal for clean cable installation, but it works. Bottom line, it gives me more reliable performance and better ease of use now that it's all set up. I highly recommend!

    PROS: Passes HDMI control commands
    Small interface box at the display end, much better than the wireless hdmi solution I was using.
    No flicker when turning on and off displays

    CONS: No HDMI out (not a huge issue)
    Doesn't like small hdmi cables on the receiver end for some reason

    Using this in a warehouse environment to distribute video to multiple tvs. Three of the Four tvs are well over 100 feet from the rack running on cat6 cable and monoprice HDMI cables on both ends. Have used multiple video sources and it has displayed them all, including audio. Just for fun I hooked up a couple HDMI splitters in front of this unit to see if it would have any problems using a weaker signal. There was no change in it's output. So far everything is working well.

    PROS: Solid solution for distribution, inexpensive, handles both audio and video.

    Great Product! we are extending HDMI over 100 ft to three Sharp Flat screens and the display quality is great.
