Wireless HDMI Transmitter and Receiver, Plug & Play Portable Wireless HDMI Extender Kit for Streaming Video and Audio to HDTV/Projector/Monitor from Laptop/PC/TV Box.

After tripping over my 20ft HDMI cable that I was running across my living room floor, I bought this transmitter and receiver hoping to save myself a bad fall. After dealing with this pair, Ive decided to risk the broken neck and stick with the HDMI cable. Each piece requires an HDMI port along with a separate power port (USB-C) but wont register a power supply that isnt plugged into the computer Ive got the transmitter plugged into. I tried every different combination of plugging in the USB into the computer, or the wall outlet, or putting the transmitter into the HDMI port, or using a converter and using the DisplayPort port, but nothing ever seemed to affect the outcome. I was spinning a roulette wheel to decide whether or not this thing would even work. The picture quality is loathsome. I recognize that-- when this thing actually works-- its got a lot to do, but even the slightest tasks you perform on your computer will make the picture freeze and (hopefully) reconnect a good 5 seconds later. Im not talking about video games, either - this waste of plastic could barely keep its head above water through the length of a YouTube video. I tried playing with the resolution and aspect ratio, hoping it would produce a better picture quality, but no. The whole screen looks like it was shoved through a 144p video quality filter and tried to recreate the 1080p quality blindfolded. So here I am, with a $130 product sitting in its box after failing to connect to anything for the 11th time. Id give this product 1 star, but those reviews seem to be reserved for people who encountered shipping problems. This product is expensive garbage and Id love to see about getting a refund.

This is great it’s very convenient works really well you can cast on one tv great for the price

So these have a good range since they need extra power. I use it on a TV and I can get video and sound without a problem.

I periodically do trainings and I like to be away from the huge monitor mounted on the wall, and sometimes even talk from the back of the room. I don’t like running long cables or being tethered to the monitor, especially if it’s an event type venue and you have a trip hazard and have to put gaff tape on everything. A secondary application is at home. Often I have my computer running in my home office but after a long day, I want to relocate to another part of my home that is more comfortable. I can very easily take my wireless mouse and keyboard and simply go to another room where I have a monitor set up. And occasionally, I will have all my video and streaming stuff hooked up to one TV and want to finish a movie or something in the kitchen or even on the patio. This is an easy way to make that happen. I wouldn’t call myself a power user and I am not pushing this thing to its spec limits for the signal. I’m not doing 4k or gaming. The listing notes that this is good for about 98 feet which is less distance than some comparable devices out there on the market. I am never in a place where I would need that kind of range. Rarely am I going more than about 50 feet away from transmitter to receiver and the signal easily worked from one room to another through walls in the same building. I didn’t sense any interference between these and other electronics and I didn’t notice any lag in the signal as I got further away or with all the other electronics used in the area. Your experience may differ from mine and you may experience some lag or stutter if you are trying to push more data through them, have content with heavy resolution, or have obstacles between the pair. For my purposes, they functioned well. The pair were easy to set up and were unobtrusive once in place. I wish there was a better option to power them but I don’t think other devices in this price class have it solved any better. The build quality was nice and compared to other options, I feel like these are quite small. Neither unit got hot during use. If they keep the price to about $120, I think it would be a solid purchase. More than that I’d explore other options.

Garbage. After about 10 minutes of use, it will consistently disconnect itself. If youre across the room you, youll have to walk back to the transmitter and push the button. Its a huge pain.

Worked well for about 2 weeks and then would not pair. Unplugging and letting it sit for a few minutes was a temporary fix, but signal was lost after about 30 min, I used a dedicated USB power source, so it is not likely that the power source was a problem.

I was using this device to connect my PC to a projector. It worked the first few times with no issues. Eventually I kept having to do things like refresh the display adapter, extend display, duplicate display, etc., reset the connection on the transmitters themselves, etc. And in no particular order, in order for them to work. And then one day they just stopped working. The RX and TX are reading each other, but for some reason not executing. I am no expert on transmitters, but inso being tech savvy enough, I tried the following when I became desperate : 1. Hit RX button for 3 seconds, took a picture of the QR code on my phone. I noted that it is an EZCast receiver. 2. I downloaded EZCast onto windows. EZCast showed the exact SSID from the transmitter. *Note, as it is plug and play, these devices SHOULD NOT require a password. However, I typed the Pal where it says password anyway. This only resulted in a mismatch. 3. But then, just to ensure I have covered all bases: I checked my driver on my PC. I turned off windows firewall just to make sure it wasnt a firewall issue. Everything checked out. Now... Here is the final verdict : My PC detected the TX just fine. There were no issues there to begin with. My projector reads the RX just fine. Again, no issue to begin with. The TX and RX are detecting each other, but are NOT performing. NO display whatsoever. FAULTY product that didnt even last 30 days. Now it is passed 30 days and is too late to return it. For $180 bucks? Unbelievable, and nobody can tell me I dont know more of what Im doing than the average consumer to come to this conclusion. Buy AT YOUR OWN **RISK.**

Evidently, there are simply not high quality HDMI transmitter/receivers anymore. This is the second one on Amazon I’ve tried and it shows static after setup, even though the throw is only 8 feet total.

I was pleasantly surprised at how well this product works. We tested it at a distance of about 40-50 through 1 or 2 walls and the quality at 1080p was great. In an open space, I think the rated distance should be easily achievable.

I wanted an HDMI TX/RX to move my TV across the room from the cable outlet without digging into the walls or floor. When I tried to use it at only 6 feet separation for a test, it setup very easily but the latency degraded the signal so badly it was very hard on the eyes. I would not recommend this product.
