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

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.

Wireless HDMI provide 1080P 30 frame resolution, good enough for slides representation

This HDMI transmitter and receiver kit works out pretty decently to not have to run long or visible cables. The setup works out pretty well for sending audio and video wirelessly to a set of video glasses, even if limited to flat out 1080p. The transmitter and receiver auto connect to each other after powered up and can auto reconnect to each other if there is a disconnect or power loss. Requires USB power to run and the cable should be decently long enough to reach most USB ports and chargers to plug in. Also comes with an HDMI extension if you need a bit more length. The main HDMI side of the cable do get noticeably hot during use, having the main body be made of aluminum with small fins could help with heat dissipation and heat management. This is for the white cable version with HDMI on one end and USB type A on the other.

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.

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

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.

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.

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.

I use these to hook a computer up to a monitor for testing and initially they worked right out of the box without any kind of setup or configuration. After that is a different story. When I disconnected the receiver from the monitor and connected it to a TV I can never get them to display a picture again. I went through all the steps to resync the transmitter and receiver for the instructions to no avail. Im not sure what the issue is but after half an hour of messing around with them I gave up and decided it wasnt worth my time. Something like this just should work without having to fiddle around with it each and every time you want to use it.

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).
