    Will this product work with a 100ft Cat6 24AWG UTP patch cable from Monoprice?
    New User U on Feb 23, 2017
    BEST ANSWER: Thank you for your question. The extender would only support a signal up to 98 feet. This would be 98ft from HDMI end to HDMI end. It may possibly work but you may experience signal issues if the run is longer than 98ft. I hope this helps.
    How would i connect the cat six cable to send the signal from my cctv dvr to my television, i.e would i need to connect both cables crossed or just t568a or b?
    New User U on Dec 7, 2016
    BEST ANSWER: Hello, and thank you for your question. For this device, it will require both Cat6 ports be used to transmit the HDMI signal. Each port will transmit a portion fo the HDMI signal, so both will be required to carry the full signal to the opposite end.
    Are there or could there be any issues when connecting to a matrix?

    Monoprice Blackbird 4K 4x4 HDMI Matrix with 4x Coax Out
    BEST ANSWER: Thank you for your question. We would not recommend connecting a standalone HDMI extender to a Matrix, Switch, or splitter. Reason being is it will add resistance to the signal and has a high probability of not functioning properly or at all. We would recommend using a Matrix that will have a built in extender, such as PID 8151.

    Is there an HDMI extender that will support the 4K resolution on my TV?
    A shopper on Dec 29, 2016
    BEST ANSWER: At the moment, we do not have one in our inventory, but I will pass it to our product development team as a suggestion. Thank you!
    Does this come in a pair? As in, if I order 1 quantity, do I get a pair or do I only receive 1 end?
    SG-2026-7333 B on Dec 19, 2016
    BEST ANSWER: You will receive a pair. It will come with one end for the sending device and one end for the receiving device.
    I would like to use this to put my computer in my media center closet. The only thing is I have dual monitors and two cat 6 wires running from the media center to the wall where I want to put my computer screens. Can I use a gigabit switch on both ends to increase the cat6 ends i have?
    Mark B on Jan 20, 2017
    BEST ANSWER: This type of adapter does not use "Active" plugged in wires to a switch. It uses two cat5/or Cat6 cables to basically create one "Long Extended" HDMI cable. You would have to run (2) CAT5/6 cables to each adapter for each monitor. Or 4 Cable runs for your two monitor scenario. With only 2 cables you would only be able to extend 1 Monitor.
    Will it work with Cat 7 cables? Oh, and generally, should both cables be identical?

    Monoprice Entegrade Cat7 Ethernet Patch Cable - Flexboot RJ45, Stranded, 600Mhz , S/FTP, CMX, Pure Bare Copper Wire, 26AWG, 7ft, Blue
    BEST ANSWER: As long as the 8P8C (RJ45S) connectors follow the B standard on both ends the cables should function the same as Cat6 or Cat5/Cat5e. However, be aware that the length limitations are inherent to the HDMI standard and not to the cabling. These are unpowered adapters and add no additional signal gain through the cable.
    Hello the specs for this product call for Cat5e/6 UTP cable. Can i use Cat6 STP?
    Jose M on May 5, 2017
    BEST ANSWER: Thank you for your question. Yes, you would be able to use Cat6 STP no problem. I would actually recommend to use that over UTP cable. Just to ensure you have that added protection.

    Do I have to connect both ports? What do DDC and TMDS mean?
    New User U on Mar 2, 2018
    BEST ANSWER: One is send and one is receive. It takes two Cat5 cables to have enough bandwidth for HDTV. I have been very happy with my unit.
    Does This adapter work connecting 1 TV o monitor? What do DDC and TMDS mean? Do I have to connect both?
    New User U on Mar 2, 2018
    BEST ANSWER: Monitor idk but it works for a tv. Not sure what exactly they mean but yes you have to connect both since it is a non powered balun. In order to use 1 cat5 you need a more expensive powered hdmi balun/extender
    I have one Cat 6 cable running between the TV and the cable box- do I need to have two (2)? Can this work with just one CAT6 plugged in?
    A shopper on Jul 7, 2017
    BEST ANSWER: You need 2 cables. The cables are very inexpensive. I used cat 6 and works great

    Is this supposed to work for Macs? We bought a pair of these for a conference room but it doesn't seem to work with Macs via HDMI out. Seems to have handshaking issues b/c the Mac seems to detect something is attached and the display shows something gets connected but is unable to establish a stable connection.
    A shopper on Mar 28, 2018
    BEST ANSWER: Yes it does but I also had handshake problems so I dropped these and have to monoprice’s power boosting HDMI cables. They have one that goes to 100 ft. I bought two at 75 ft. For my Apple TV and projector theater room and split it off to two othe TVs in different rooms. They work flawlessly and picture quality is fantastic no more handshake issue. So if you’re under a hundred feet go monoprice’s boosting HDMI cable.
    Scenario: I have my TV in the living room and will have a satellite receiver in the basement. There is no HDMI cable connecting the TV to the receiver, however there is an ethernet cable running from the TV area in the living room to the receiver area in the basement.
    Will this HDMI Extender work in this case?
    A shopper on Jun 22, 2017
    BEST ANSWER: Hello, thank you for your inquiry. If there is only the one ethernet cable running from your living room to the basement, this product will unfortunately not work as it requires a total of two ethernet cables to send the signal. However, we do offer other units such as Product ID 14158 (attached) which will work over the single ethernet cable.

    Will this work over a network switch?
    Dave F on May 2, 2017
    BEST ANSWER: No - this is extending over CAT5e. It is NOT an ethernet port.
    Will this work with a VGA Adapter? For example an VGA to HDMI Adapter?

    Monoprice HDMI to VGA Kit
    Monoprice HDMI to VGA Kit
    BEST ANSWER: Thank you for your question. It would not be recommended to extend from a converter. The added resistance on the signal could cause handshaking issues or cause too weak of a signal output. It would be best to use a powered converter or a more powerful extender such as our external powered HDBaseT extenders but it could possibly still run into issues. We do offer a 30 day return policy and you can return it should you try it out and it does not work.

    Hi there,

    Does this MST support dual-mode? Can passive HDMI adapters be used after the hub?

    Also, can the signal be converted to HDMI and then extended over Cat5e?

    My goal is to split a Dsiplayport signal into 4 HDMI signals over a long distance.

    Thank you.

    Versatile and Affordable
    I purchased this extender pair when I needed to be able to view my computer screen on a television a floor below the office where the computer resides. By connecting this at the television and at the computer, and then running a pair of in-wall ethernet cables between floors, I now have a great-looking, permanent solution, and I'm planning on expanding it further when I develop another room of the house into a media den. The ethernet I used was terminated at the wall with a typical keystone jack, with more-nicely-finished CAT5e cables running from the wall jacks to the sender and receiver units for a "professional" look. Even with six lengths of ethernet in between (three per channel), there have been no issues with signal loss.



    The only reason I can't give this a perfect 10/10 is because the weight of the sender and receiver ends is sufficient to put some minor strain on the HDMI ports they are connected to. Left hanging by themselves, they are susceptible to the "male" end of the sender/receiver bending very slowly over time, especially if the ethernet cables connected are accidentally tugged. Fortunately, this is easily remedied by securing the "box" of each unit against something structural I used double-sided tape to affix one to the back of the TV, and used cable ties to bundle the unit with other large cables coming out of the back of my PC, to lessen the strain.

    PROS: Extraordinarily easy setup.

    Versatile not easily confused. Ethernet can be adapted/re-terminated mid-line without causing too many issues.

    CONS: Weight of the sender and receiver units can put strain on the HDMI port they are connected to.

    Great Extender for Cost
    Works in 1080p most people say it doesn't but does. Make sure your tv can handle 1080p most tvs under 42" only run 720p because you don't need or will see the difference from 720p or 1080p on smaller size tvs. This extender does not work with the 4x4 matrix from monoprice. However if you use a 1x4 or some type of switch after your 4x4 matrix it does work fine.

    PROS: 1080p

    Cost

    100+ Ft

    CONS: Does not work with the matrix 4x4 that mono price sells.
    February 26, 2014
    It does work, but...
    This item does work with my 2 50ft manufactured RJ45 cables. I have not tested this product with longer runs. One major point to keep in mind is that trouble shooting/pro installation/dealer support is always key to any product purchase.

    I often see friends and fam waste their time returning products because the product "doesn't work" when it is initially plugged in. Please do yourself a favor and trouble shoot before you return any company's product. Human error and/or lack of realistic expectation are major factors in any purchase.

    This item did not work when paired with my VSX-03 Pioneer Elite AVR. However, when tested with both my DirecTV boxes and Xbox 360 (after adjusting output settings) it perform as advertised. Please keep in mind this AVR is several years old. It functions currently with a 24ft HDMI to my PRO-111 plasma perfectly.

    It's hard to know all the pros and cons to a product unless you consult a true professional. I am keeping this product for future use.

    PROS: Cost effective.
    No need additional cables or power supply.

    CONS: Didn't work with my AVR. NOT this products fault! I believe a powered version or in line HDMI repeater would work but I have not yet tested.

    5/5
    I used this in conjunction with two Monoprice 50ft shielded CAT6 cables run through my walls to connect my pc to monitor. Worked like a charm - no noise or degradation of quality. My monitor also has an analog 3.5mm output for audio which converts the digital sound input from the HDMI cable. I was worried this may not work but I was happily surprised that it does!
    December 13, 2011
    5/5
    This is a great way to extend HDMI video throughout the house without having to worry about HDMI cable prices. Not that Monoprice does not offer great prices... But this item truly gave me flexability and room configuration options. We are always changing the layout of the house and love that we can always use the extender between our TV and the computer.

    PROS: Portable, Convenient, and Versatile.

    CONS: None
    May 1, 2012
    Works great with newer TV
    Works great as advertised. Running a short distance of about 20 ft picture is perfect. I replaced a set of intellix ($$$) baluns that was running an analog signal. Since Direct Tv changed their software, I was having to change to 480 every time I wanted to watch my kitchen TV and then back to 1080 going back to family room. Only I kept forgetting and was watching standard def on my 60" Sony half the time! Now I have HD signal going to both and no longer have that problem!
    I had this connected to a 3 year old LCD TV and got no signal. I thought the product was either defective or didn't work. Monoprice promptly cross shipped a replacement. The replacement didn't work either. I was ready to get a new thinner LED TV for the kitchen island and decided that it was worth a try to see if the TV was the issue. Lo and behold it was indeed the TV. The new set picked up the HDMI signal no problem.

    PROS: Works great as advertised

    CONS: May not work with older TV's even if they have HDMI
    January 19, 2012
    Work Great
    Good product thus far, just as stated in specs. Using Cat5e, carry signal from a central AV room. Have not encountered problems. Purchased one set as a test, after good performance bought 4 more and replaced powered units.

    PROS: Non-powered, stable picture. Inexpensive.

    CONS: Reviewer advised cannot be used in a splitter. Cannot carry 3D.
    June 27, 2015
    Works great...till it doesn't
    Using this off HDMI splitter and Cat5. First set I got was DOA. Second set worked great with none of the picture or audio problems other reviewers experienced. Second set stopped working completely after 9 months of very infrequent use (a couple of hours per week). Monoprice approved an RMA for the second set, since it was the 2nd failure and within 1 year of the RMA. Thanks for standing behind your product...that's why I keep coming back to you guys!

    PROS: Ease of installation

    CONS: Reliability
    September 28, 2013
    Works, but with Cat6 UTP is susceptible to power fluctuations
    Works fine with Unshielded Twisted Pair (UTP) except when power fluctuates. I also bought the $40 set that has 5V power on the receiving end, and it is not susceptible to power fluctuations. I am using unshielded Cat6 cable with keystone jacks on either end. I tried to shield the cable from electrical wires, but that is hard to do. There is one stretch of cat6 that is 3" from a parallel power wire. I have a friend with this exact same extender who has not experienced this problem at all.

    CONS: There is a 1 second cutout in audio/video whenever my microwave door opens, fridge door closes, a light goes on, or any appliance turns on.

    More hits than misses, but the misses kill it for me
    I'm an A/V installer, and these little gems are both my best friend and nightmare. Never mind length issues because I've gone 85' and had zero latency, or 14' and complete failure.



    My most common use for this passive HDMI balun kit is as a backup to what ever it is that me or my crews are installing. We do not spec these units into jobs, they just show up when options are limited, and we explain that.



    Do yourself a favor and try one pair of these Baluns (with two 50' Ethernet cables from Monoprice.com of course), between your existing AVR, HDTV, or STB, and see what results occur.



    Please do not go out and pre-wire a house thinking that these HDMI baluns will save you cost. Otherwise you'll be paying quintuple the price buying all the gear that you were smart enough to look up the internet, but not to actually buy.



    Don't say you haven't been warned.

    PROS: These little things work great, until they don't.

    CONS: Those $150 active (powered) baluns don't look so bad now do they?
    March 12, 2015
    Response from Monoprice
    Hello,

    Thank you for your review and truly sorry to hear about your experience with PID 8121. Would you happen to have your order number so that I may look further into the matter? For troubleshooting purposes, have you tried switching out the cables and connecting to a different source or device?

    Another thing you may want to try is power cycling the extender. Disconnect everything from your setup including power and cables. After about 5 minutes, plug everything back in and power everything back on. Also try powering everything on from the display and work backwards in the chain to the source device.

    Please let me know if the above steps yield any results as well as your order number so that I may further assist you. Thank you for your cooperation in the matter.
