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

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.

This is a very easy to use HD antenna set that includes one dedicated transmitter and one dedicated receiver (and they’re each clearly labeled). It’s pretty much just plug and play since each end instantly recognizes the other and connects (though you may have to attach the included USB power supplies to them to get them to work). The picture quality is basic 1080p so don’t expect to be able to stream 4K content with these, but they’re a great option for work-related presentations or projectors that only offer 1080p resolution anyway. Overall, this is a well made and easy to use pair of basic HD antennas that sells for a pretty fair price. Four stars.

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.

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.

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 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 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.

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.

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

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!
