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

Im so glad Ill never have to worry about having the correct length HDMI cable again, or tripping over a cable stretching across a room. This works and works well. Connection was as easy as plugging in both ends and waiting a minute for it to self-connect. Picture quality is good on 1080 and 720 screens, and theres virtually no lag. I tested this with a laptop and several Samsung devices as senders and a projector and several monitors as receivers. All of the connections were easy and stable. Im not sure on the power requirement, but I was able to plug the power end into my projectors built in USB port for power. Idk if its meant to, but I noticed the HDMI plug-end gets hot during extended use (several hours or more).

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!

Ive been begging for years hoping a wireless HDMI would someday exist and seeing this product go live I jumped at the sight to try it out. It was so easy to set up that literally anybody could pick it up and know exactly what to do. The hdmis are labeled so it was barely even a few minutes to set up to see literal magic before my eyes. I was actually blown away with how far technology has come and will be looking into buying more!

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.

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.

I did have to fidget around with it to get it going on my new Sony TV, but now that it is up and running, it works great. Even though I have a brand new TV, the USB output was less than 1 amp, so I had to come up with a 2 amp USB power supply (at this price point, they should have included one). Luckily, my laptop did drive the transmitter. Once I had the power situation figured out, it came down to the laptop handshaking with the input. I was worried about the pairing, but apparently it was paired the whole time. I believe the key is that both units had a steady light on the button. I finally got it working by going out of the input and then back into the input. The video just came up. The video quality is great, it is smooth with no hitches or delays, and there is no discernable lag with the audio. Now that everything is in good order, it is a pleasure using this device.

The Wireless HDMI Transmitter and Receiver worked well for both video and sound. I was able to send 1080p Full HD video and sound at 60fps with no noticeable latency. The dongles felt a bit too flimsy and can be squeezed almost too easily. The caps needed to be attached to the units with at least a string so that they dont get misplaced. Both the transmitter and receiver MUST be powered via the micro-USB ports. Pairing was easily done by holding down the button on the transmitter.

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.

The Wireless HDMI Transmitter and Receiver, a remarkable innovation in the realm of technology. This cutting-edge device serves as a bridge between your laptop or PC and your HDTV or projector, enabling seamless streaming of high-quality video and audio. Its wireless functionality liberates you from the shackles of cumbersome cables, providing unparalleled convenience and flexibility. With its sleek design and compact form factor, it effortlessly blends into any environment. The superior transmission capabilities ensure minimal latency and superb image and sound quality, delivering an immersive viewing experience. Its a game-changer, revolutionizing the way we connect and stream media, and it truly deserves accolades for its exceptional performance and reliability.

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.
