BRILOCEA Wireless HDMI Transmitter and Receiver, Wireless HDMI Extender Kit for Laptop and PC, Plug & Play, Wireless HDMI Dongle Adapter for Streaming Video/Audio from Laptop/PC to HDTV Projector

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.

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 kit works really well especially with my projector machine. Just use my console or computer to transmit to it. Really user friendly and great value for the money.

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.
