The End of Signal Conflict!
Reviewed in the United States on 4 September 2018
Recently, DirecTV installed a "wireless" Genie receiver and the associated server (storage + transmitter). Simultaneously, we upgraded our WiFi from 100MB to 200MB (both with a 2G and 5G designated network name). This was all associated with the acquisition of a new Samsun Q6 82" UHD-TV and a Sony 800 UHD disc player (with WiFi and streaming).
If signals were visible, our house -- perhaps likes yours -- would look (inside) like a spider-web of 2G, 5G, and other signals we use to control 6 Amazon Echo Devices, 2 iPhones, 2 Windows 10 laptops, 2 iPads, 1 iPad mini, 2 UHD and 1 HD TVs, and even an Apple watch. I've lost count of the number of Kindle's (there must be at least 3 or 4) we have accumulated, too. Finally, my wife has two MacBook Pros -- and one of those is almost always on, always connected wirelessly to our WiFi).
The 82" TV is hard-wired so that we can get a clean drop-out free 4K signal. The LG HD TV in the kitchen HAD been connected wirelessly using a Nyrus 1080P wireless extender; also, the Samsung UHD TV in the bedroom was connected to DirecTV via a second Nyrus 1080P transmitter and receiver, just like the one in the kitchen.
OK, so we fire up three TVs (all with the same content -- let's say DirecTV) so as we work in the kitchen, go to and from the bedroom and family room, we don't miss the program. Then we start using FaceTime in one room and one of the Amazon Echos in another room and alternatively DirecTV drops ("connecting" or "no server found", etc.), then when DirecTV comes back the Nyrus connected TV in the kitchen drops, comes back, freezes -- and then stabilizes which immediately causes the bedroom Nyrus connected TV to drop, come back, freeze. The only TV that remains on (at least as long as the DirecTV doesn't drop its signal) is the WIRED 82" UHD Samsung.
We had all but given up, thinking we would have to have a 33' HDMI cable run to the kitchen TV, then I found the J-Tech Digital HD Xmit and Receive products here on Amazon.
Today, the J-Tech arrived: I unplugged the kitchen TV (using the Nyrus unit) -- and replaced it with the J-Tech. When power was applied the kitchen TV came on within seconds -- perfect picture and sound (from the LG's measly speaker -- which is to be expected from a 24" flat-screen TV).
The bedroom TV and the 82" UHD unit (bedroom in HD, family room in UHD) and the DirecTV "server" and "client" continued, not dropping a bit (or missing a beat).
My WiFi is powering 2 iPads, the DirecTV server and the Microsoft Surface I am using to write this review. I can see the 82" UHD and the 24" HD TV from my perch here on the couch. Both of them are showing beautiful pictures -- and I just walked into the master bedroom and the 55" UHD TV (showing upconverted HD) is also displaying a beautiful picture (and sound).
Whatever frequency the J-Tech is on seems to have untangled the virtual spider's web of invisible transmission signals that are now working together in harmony (and probably slowly cooking my brain -- as if I'm in a giant microwave of WiFi and audio/video transmissions.) Three TVs (all of them at a minimum HDTVs) are now able to play, glitch-free simultaneously. Of course, it is possible, too, to have one TV watching Amazon Prime, one watching Netflix and the third watching DirecTV or a 4K HDR movie (only the 82" can actually display true UHD HDR of course).
In all fairness to Nyrus, I had been using THREE 1080P HDMI transmitters and receivers simultaneously with very little problems -- for over five years. The addition of super-duper WiFi AND the DirecTV wireless server and receiver devices probably overwhelmed the spider-web network in our house. I would have no problem recommending the Nyrus 1080P units with the caveat that using more than one of them simultaneously could cause signal-conflict issues.
The J-Tech "feels" and looks like commercial-grade hardware -- nothing flimsy about it. It is THE EASIEST to install product (of this nature) ever. That a second receiver could be purchased is ideal for those of us that want one or two satellite TVs playing simultaneously.
Good price, great video and audio -- wrapped up in a heavy-duty package (so far) that is super easy to install.
The ONLY issue is there is a bit of audio latency which is problematic if you turn up the volume on the satellite units meanwhile you have the main system also turned up loud enough to be heard while you are in the proximity of the satellite units. This ONE issue is a first-world problem, of course. The solution, turn the satellite units down or turn the main unit's volume a bit lower.
Overall grade A-. I'd get another unit without hesitation (unless they turn out to be unreliable or proven to lack durability). I may end up getting the second receiver and put the older Nyrus unit (which is still soldiering on, in the master bedroom) into my "museum of older technologies" aka, the basement.
If you've tried wireless HDMI 1080P previously without much success, this unit may very well change your mind.
Do it today.
