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

This HDMI Transmitter/Receiver is Plug and Play and has a great transmission distance. It transmits not only video but also audio. The examples of its applications are vast, but Ill refer to my own experience. As a university professor, a significant portion of my courses are conducted online, while others involve student gatherings. For these purposes, we rely on an audio and video system. Therefore, these modern pedagogical methods make the use of such tools essential. Personally, I used these wireless HDMI connectors to transmit from my laptop to a 100 audiovisual projector. Here, Id like to share a crucial tip that I consider vital when using them. Its important to properly connect each one (transmitter/receiver) and power them via a USB-C cable with 5V-2A. This information was not included in the manual, and I was almost frustrated because I couldnt get them to work. Even though the devices indicated a connection between them, I had no idea what magic trick to try. So, I took a deep breath. (Clarification: In my opinion, those USB-C connections were intended for charging the transmitter/receiver devices, just like a cellphone or Bluetooth headphones. But surprise! They dont charge; they simply receive power. Thats the key. I connected them to a power source using a cable with 5V-2A, and voilà, the transfer started with clear video and sound! They worked like a charm. However, dont forget that they dont charge; they simply receive power.

This is a great little device that you will use a lot. There was virtually no setup - I plugged the transmitter into my laptops HDMI port and the receiver into the TV HDMI port and, in no time, I was mirroring my laptop stream to the large tv monitor. This is really convenient when showing movies from my DVD drive or those I ripped to a hard drive. It is also great for presentations at meetings. This is a must have for any videophile that does serious streaming to a tv or monitor. Also, it comes at a really good price so it makes a nice gift.

I was very surprised that this worked so well, and right out of the box. I remember trying a similar product a couple of years ago, and it was unusable. This thing had no problems. It gives a good image (there is a little compression, of course), and is extremely easy to use. On top of that, the latency is quite low. I think that it pretty intensely uses the graphics card of the computer that it is plugged into, so for that reason, I would not recommend it for gaming. But for work, for presentations, putting up movies and streams on a monitor or tv that is hard to reach, this thing is by far the best solution Ive come across.

Pairing this with an HDMI splitter, my husband can watch satellite TV in two different rooms. hes pleased with the results.

Given that it was literally the best deal available when I got it, I am genuinely impressed with how well this HDMI transmitter receiver set worked. I just plugged the transmitter into the device HDMI output and the receiver into my television HMDI input, and the USB power ends into the closest USB ports around, and boom, it just paired up and worked automatically, transmitting quality picture and sound right away. I plugged the receiver into my GoPro Hero 8 Black Media Mod HDMI output (well, the normal HDMI end of a cable that adapts the media mods micro-HDMI) and the power-USB end into a USB battery pack and - Awesome! - instant zero-lag casting from the GoPro camera to the television without any software, cloud, subscriptions, complicated pairing configurations, apps, wifi hotspots, etc. Finally an easy answer to this problem - AND! - it was really cheap! Just a fantastic buy and Im very satisfied; I recommend highly without hesitation.

Tested with phone and laptop transmitting to TV. Image quality was good and no visible lag. Tested distance to about 20ft with no issues.

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.

This is a wireless wonder of a specific kind. When connected to a laptop and to a TV, it worked exactly as described. When I tried connect it to an all-in-one pc and a monitor the connection screen appeared but the mirror mode never came on. Image quality (when it connected) was excellent and the audio quality was equally good. I didnt experience any lagging issues or de-synchronization between audio and video. Others reported that the inputs got warm and I too noted that they were warm to the touch. All told this wireless system works when used exactly as detailed.

I was perhaps more curious than informed on this device? Wireless mirooing says it all! The set up and instructions were not a steep curve….but experiemcing how it changes and adds to many display and source options in my HT / Office was a very pleasant discovery! Seeing media from my IPhone wirelessly on my flat screen is a new world of connectivity between my devices! This adds image targeting and sharing options you think could never be done? Plug & play wireless mirroring (PPWM?) The vendor specs do a far better job of detailing all the uses and connectivity this Dongle offers than I can. BUT read the ‘Notes To Buy’…..it works great in many cases..but not the ones you may wish it would due various ‘copyright protections’. It was just a little less useful for me because of these issues. Would I use it from now on....yes!

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.
