Wireless HDMI Transmitter and Receiver, Wireless HDMI Dongle Adapter Designed for Laptop & PC for Streaming Video/Audio from Laptop/PC to HDTV Projector

Software solutions for mirroring a screen are all different, whereas hardware HDMI is HDMI; the same everywhere. This hardware solution to screen mirroring is painless and a pleasure to share a computer screen with a large TV. If the HDMI power from the source and target is insufficient, each receiver (RX) and transmitter (TX) allows a micro-USB port for external power. The image mirrored is precise and responsive.

Im a little torn on the price, however it is what it is and you know what youre willing to pay or not. So Ill leave that alone because in the end, it worked quite well. I didnt feel very much lag at all when using it with a projector as an extension of my desktop and it served my needs in my office perfectly. My only concern is how hot the connectors get when plugged in. It seems like they might do well to incorporate a small heatsink on the HDMI connector ends to try to combat that. It wasnt so hot I felt like it would burn me or anything, but it was still hot enough to make me think to disconnect them whenever not in use just to be safe.

I got this to avoid using an HDMI cable at events where we needed a portable scoreboard, and with my projector and portable screen this was a no-brainer to put that scoreboard closer to the guests who came to the roller derby bout. Connecting is a no-brainer as the transmitter and receiver are paired at the factory. I do wish my laptop had more old-style USB-A ports to connect this with, but I used an old phone charger to supply the necessary power to the transmitter and I was up and running. The resolution is great (looks crystal clear to me, so likely is the full 4k they claim) and within the distance claimed I had no problems connecting. There is a bit of lag between when I move my mouse and when it moves on the screen, but its nothing I cant work through. I had not expected audio to transmit as well as video, but when I broadcast some videos from my laptop onto my TV the sound was definitely coming from the TV (which means no more HDMI cables on movie nights - YAY!). For what this does, I am blown away by how well it works and how simple it is to use - this is MUCH better than any Chromecast Ive ever used as I get to control what I cast and it doesnt have to be in a web browser.

Plug in and play is false advertisement, this product does not work..

I never knew these types of HDMI cables existed for wireless displays, but they work amazing. Straightforward and to the point to instructions and they work flawlessly for me.

One of the greatest inventions for home A/V that has come down in a while. One of the reasons so many people have dropped cable is that cable companies make you get a converter box for each TV in your house, which you pay for monthly. If you cut the cord and go with a streaming service, you can stream from any TV you want. With this device, you can split from one cable box, and send a perfect picture to another TV. And it just works! Plug it in and go! This is actually my second set, and I got it so I could beam from a laptop to my portable projector to watch movies on the pool deck. I have not done that yet, but I sent from my laptop to another TV at the same time the original set was transmitting from a cable box to a different TV, and each seemed to work just fine independently with no interference. These are truly great, and unlike so many electronic devices which claim to be plug and play but arent, these actually are!

I ordered this to use with a client who is doing live streaming classes via Zoom and wanted to mirror a computer to a TV screen so he could see and interact with class participants. When I opened the box and took out the transmitter, I was surprised at how very light it was. In the pictures it looked like aluminum but its actually a rather cheap-feeling plastic. I plugged the unit directly into the HDMI port of my 2022 MacBook Pro but then discovered that the unit is so wide that I couldnt plug the power cable for the unit into the USB C port beside it. I then used the HDMI extension cable to plug into my laptop. The included cable to power the transmitter/receiver has USB A on one end and micro USB on the other end...neither one of which is supported very well on modern laptops. I had to use a USB C to USB A adapter to plug into my computers USB C port. Then I plugged the USB A to micro USB cable into the adapter and transmitter unit. By this time I had quite a snarl of cords and adapters next to my laptop. I then plugged the HDMI receiver unit into my TV. I had to remove another HDMI cable to make room for the bulky receiver unit since there was only one HDMI extension cable included. I had to use a USB power bank to power the receiver since my single USB output on the TV went to my soundbar. Now I was finally ready to test it out. This part was pretty straightforward and easy. Just push the button on the transmitter and my laptop screen was mirrored to the TV. As soon as I did this, the resolution of my laptop screen got much bigger so the windows and font size reduced considerably. These smaller windows and font size were also mirrored to my TV. To test, I tried streaming a TV show from a popular streaming service onto my TV from my laptop. There was a very noticeable delay as I watched the picture on my laptop and compared it to the TV. It seemed like about a 1 second lag. The advertising says plug and play, no delay but this was not my experience. Even with my laptop just 4 feet away from my TV there was a significant delay. This wouldnt matter much if I was just streaming TV shows, but I ordered this for live online classes via Zoom. This means that there would always be a significant lag time between a class participant speaking and seeing/hearing it on the TV. This would get frustrating quickly with people trying to talk over each other, thinking the other had finished speaking. Overall, this was a disappointing experience and did not do what it was supposed to do. For this reason I cannot recommend it unless you dont care about the lag time.

I dont know about you, but when I saw the picture, I had absolutely no faith this would work well. Just a cable with two connections? How could that work? So, it actually has two cables. One is for output and one is for input (self explanatory.) It is powered by USB. So I used my computer out HDMI and USB (A) for power. Plugged the second cable into my TV about 40 feet away, HDMI in and USB for power. That was it. It worked perfectly. The directions are basically non-existent, but who needs them!? Nothing to this. It does comes with a black HDMI extender, but that is necessary only if you need more cable length so you can reach the HDMI port or the USB port. Nothing special. Overall, works fine in the distance I tried. I am going to try a more complicated use in the next few weeks and will update if there is any change, but I am 100% convinced and a believer. This is way too easy! I hope this review was helpful!

SET TOP BOXES: Can get audio and video with my Android TV and ATSC Converter boxes. But, receiver will sometimes give a No signal message once or twice before stabilizing. Sometimes connection restores within a minute, other times need to unplug and replug. That seems to be either a power or WiFi problem. Good audio and video quality when working. CHROMEBOOK LAPTOP: Product displays ONLY the Chromebook background image, and plays audio. Wont display the cursor or anything on top on the background such as the browser. WINDOWS 7 LAPTOP: Will mirror the display but no audio. Image quality seems comparable to a wired connection. Didnt bother to check for lag since no audio is a deal-killer. BLU-RAY PLAYER: Video only, no audio. Both sending and receiving units get pretty hot, though sometimes only just really warm. Product description of operating principle makes no sense - Bluetooth to get network WiFi credentials, then operation via WiFi. Sender and receiver are their own P2P network. Confirmed that shutting down my home network doesnt prevent the two units from connecting. And, it makes no sense to use the home WiFi. That would just add extra latency/lag to the performance. Failure as a wireless HDMI for laptops. Glitchy for set top boxes. Basically, this product should work with any HDMI device, though its advertised as being only for laptops, PCs, and set top boxes. But, it doesnt work with Blu-ray players. Didnt check with game machine or PCs, and dont have adapters for mini- or micro-HDMI. A big disappointment.

This is much more convenient than the other wireless HDMI transmitter/receiver kit that I have to use separate power wart. It works very well with most of my TVs, except for the very old one that doesnt have a USB port to power this. Theres a short delay, about 1/4 of a second, from the source laptop to the TV. Its only noticeable when I have audio output on the laptop while watching the TV. The lips doesnt sync. This is an issue when I output audio from laptop to the stereo amp. The way to remediate this is to take the audio output from the TV to the amp; that way the video and audio are in sync.
