J-Tech DigitalWireless HDMI 4K Extender Zero Latency 30M (100ft) Line of Sight 4K@30Hz HDCP 1.4 with CEC Function for Gaming, Live TV and Desktop Computer [JTECH-WEX-60GA]

I upgraded my home theatre and the original hdmi cable couldn't support the newer standards. The cable was wedged in the ceiling such that my electrician couldn't get it out so I went looking for a solution. I couldn't get a picture at all from these devices initially and spent a couple of days trying everything and in desperation switched the power source to the rx & tx from usb power to mains power and it fired up straight away. J-Tech - please put this as a troubleshooting suggestion on your support site. The picture is good but sometimes the devices don't sync when I first turn the projector on, so I have to power both devices off and on to get it working which is frustrating. So overall, not as good as a cable connection but I'm glad a found a solution in the end.

I've tried FOUR other systems that claim to do what this one actually does. I have a 75' lin-of-site shot I need to duplicate my TV on (inside TV to outside TV next to firepit). You can literally see both TVs when standing between them and I've slowly worked my way up to this unit dollarwise. It seems that to succeed, you have to spend the money and get this unit. It works great! Finally! whew.....

I have it for a few days, it's super simple to install, just plug and play, it response fast, I have it on a home cinema device and sound and image is perfectly synchronize, still pending to install home audio equipment for being able to mention something on the sound quality, however on image you can notice a slight lost on quality not a big deal but perceived Vs. Cable, any way rather to have this slight lost than running and protecting cables.Something nice is the size of the devices, are way smaller than what they look in the pictures they fit in your palm what makes them perfect for being discrete!

Good product, works well. Very simple to setup. They should tell you that it runs in the 5Ghz WiFi band on channels 149 153. If you don't move your access point off of those channels, you will struggle to make it work. We spent one hour trying to get it to reliably link from 50' away. As soon as we moved our access points to the low end of the 5Ghz band, it worked flawlessly. Went from barely working line of site to working no matter how or where we plugged it in. Key point to remember.!!

I have so many problem with the first model ( we end up buying a new TV because they told us that is my HDMI input in my LED bad,not true).Here is one of many email conversation:"That is the first thing I did was to scan for any 5 GHz network in the area. If you look at your amazon product description it gives you information on how to troubleshoot your video signal and quality, and to scan your network to see if anyone (devices, routers, etc) uses the 5 GHz network channels 149 and 153.I used 3 types of apps "Wifi Analyzer", and I did not have any devices or routers that operates on the channels 149 and 153. I only have routers that uses 2.4 GHz on channels 1, 4, and 11. Plus the routers are 200 to 450 feet away from the receiver or the transmitter.I only use one TV 55” LCD (VIZIO Model D55N-E2), the second TV was my portable HD LCD for testing equipment, that is the only time I used my portable HD LCD is to test that the video feed is coming in thru my 6 feet gold plated HDMI cable, (NO SLITTER INVOLVE). The first time I had a cheap HDMI cable $10 now the new gold plated HDMI cable is $89, I still have the same problem."10 days of communication, the owner to to business I install hate it at first.I ok for now, we should see how long will it work.PLUS I'm using it only around 120 feet for 600 feet device (they claim that), I had to move the TV in order to work (20 more feet) because I was over 140 feet and will not work.

I built a house in 2009, and it wired, it was supposed to be state of art.. and I've had sporadic 'Handshake' issues with my TV/Audio for almost 6 years, I will never pre-wire a house again. About 3 years ago I switched to wireless HDMI, and gave up on the cabling.. but needed the wireless so I could still make use of the speakers I have in the ceiling, which require an AV Box in a being in a closet at the opposite side of the house.. I did this utilizing the regular type set-up available from places like Best Buy for $150/$200, and I've lived with the fact that every time I turn the system on, I have to re-set the boxes as a minimum, and then due to sporadic loss of picture, and sometimes sound, I would need to Power every thing down, and then turn each component on in the right order, as a maximum; DirectTV, AV Box, Wireless Transmitter, Wireless receiver, and then the TV.. Over the 6 years I've bought new HDMI Cables, and New AV Box.. but nothing fixed my issues completely.. About a month ago I cancelled DirectTV, because I was tired of paying over $100 per month and switched to cable.. and my Handshake problems increased.. anything I tried would fix the issue for a few hours, and then boom.. Green Screen, I've spent 1,000's of $$ and I can't just turn the TV on in my house and watch it.. absolutely infuriating.. Enter J-Tech Digital.. I did some research and decided to try this superior product as a last ditch effort before just giving in and writing off the fact that my house is wired.. and sticking the TV and Boxes altoegther in a corner, and buying new speakers.. I was skeptical.. but you know what it just works.. I wasn't expecting that.. you turn the TV on, and there's a picture, you switch from Apple TV to cable, and there's a picture, and I have surround sound, and it just works.. I cannot praise this product enough, granted I'm not transmitting 650 ft but I am going through multiple walls, and it's perfect!! Thank you J-Tech Digital!!

Have not yet tested maximum range but appears to work well within 30m.latency is as described.
