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

The wireless hdmi dongles worked well and were easy to set up.

This works pretty well, although it did not result in my laptop screen being automatically being mirrored to my monitor. I had to bring up my windows display settings and configure the display setup there. Fortunately I’m familiar with configuring windows. The documentation included with HDMI transmitters is sparse, so those unfamiliar with windows configuration may struggle. The Amazon product page for the HDMI transmitter states that it will not work IOS devices such as an iPad. This is not true. For an iPad you need an USB C to HDMI converter. For an iPhone a Lightning port to HDMI converter will do the trick. As in MS windows, once you’ve made the connection, you’ll need some additional configuration to get the remote window to look and act like you want it to. Although the receiver and transmitter seem identical, they are different; one is labeled computer and the other TV/Monitor. One disadvantage the HDMI transmitter has when compared to a plain HDMI cable is that the HDMI transmitter and the receiver need access to a USB port to power both the Transmitter and the receiver. I was able to cast my laptop screen to my TV in another part of the house using the HDMI Transmitter/Receiver combo. One thing I noticed is that both the transmitter and receiver got quite hot after a very short time of connecting. I’m not sure what that means for long term reliability. One other thing I noticed, that may or may not be relevant, is when I attempted to look at some other reviews for the HDMI wireless HDMI extender kit, I found most of the reviews were for another product entirely. The bottom line is this may be a useful kit for transmitting from your PC or other device to a display that is some distance away, provided you’re willing to a bit of configuration.

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 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.
