Wireless HDMI Transmitter and Receiver 4K Kit, Full HD 4K Wireless Presentation Equipment HDMI Adapter, Plug and Play Streaming Media. Laptop, Dongle, PC, Smart Phone to HDTV/Projector 165FT/50M

Picked this up for our church and it’s been fantastic. Setup was super easy — literally all you need to do is plug it in on both transmitter and receiver sides and it works right away. Certainly saved us from running long HDMI cables across the sanctuary which was our ultimate goal. We’ve used three times a week for our services and it hasn’t given us a single issue. The signal holds steady even with some distance, and our production team has commented on how clean everything looks without wires everywhere. If you’re looking for something reliable for church or any group setting, I can honestly say this has been worth every penny and that we have no regrets!

So far so good. This was plug and play and was working right out of the box. There did not seem to be any lag with the video or audio. I only tried it with a direct HDMI connection did not use for any casting. The quality of the picture was as advertised. Overall, after a month's use I would say this is a pretty good product.

This wireless HDMI transmitter/receiver works as advertised. I use it primarily to project videos from a MacBook Pro to a home theater system. It connects automatically and supports full 4K resolution. The USB-C ports on the MacBook also provide enough power to the transmitter so that an auxiliary power cable is not needed. There are no noticeable audio/video synch issues and no noticeable lag between the computer and the monitor. I also like the fact that this one has a power switch on the side so I can turn the whole thing off when not in use. I am very happy with this purchase.

I used to use this at my last job as they did not allow smart TV's on the corporate network for security reasons. I just plugged this into my office TV and also my dock and it worked great. Connection was reliable and gave a full 4k picture which was great quality.

I believe this is exactly what I was hoping to get out of this product. It was a breeze hooking up and gave me the ability to use my DVR on my security system. The product needed to span over 100 feet so I would be able to see patrons enter and exit our indoor mini golf course.

Setup and Installation The setup process was surprisingly straightforward. The plug-and-play design had me up and running within minutes - no complex configuration or software installation required. Simply connect the transmitter to your source device and the receiver to your display, and you’re ready to go. Performance and Quality The 4K video quality is impressive with crisp, clear images and vibrant colors. I experienced minimal latency, making it suitable for both presentations and entertainment. The wireless range works well throughout my home/office, maintaining stable connection even through walls. Key Strengths Crystal clear 4K resolution - No noticeable quality loss compared to wired connection Reliable wireless connection - Stable signal with good range Easy setup - Truly plug-and-play experience Versatile compatibility - Works seamlessly with laptops, gaming consoles, and streaming devices Low latency - Great for real-time applications Areas for Improvement Occasional brief connection drops during extended use (easily resolved by power cycling) Could benefit from a more compact transmitter design Bottom Line This wireless HDMI kit delivers on its promises. Whether you’re giving presentations, streaming content, or gaming, it provides a reliable wireless solution that eliminates cable clutter without sacrificing quality. Great value for the price point. Would I recommend it? Absolutely! Perfect for anyone looking to go wireless without compromising on 4K quality.

So what do you do with these? You hook up the HDMI transmitter dongles (plural??) to several sources with the SINGLE big receiver station with antennas and you can swap between the transmitters all to broadcast to just a SINGLE video source. I do not know how this is useful in any capacity?? I mistakenly assumed that the HDMI transmitter dongles were actually the receivers (you can purchase more of these) so that you can broadcast HDMI signal TO several sources. But nope, it's the other way around where you can receive signal from several sources. If you're in a conference room it's FAR easier and FAR cheaper to just I don't know, send the file/powerpoint/whatever to a main computer that's hooked up to a video source? Or if you already have a laptop with HDMI output (something you need anyway with these), you can just walk up to wherever the video source is and hook up your laptop directly? I don't at all understand how this is a workable solution if you have several transmitters. It's extremely pricey too! The only thing I can think of where this may be useful is running a single wireless HDMI source when you don't want to run cabling through the walls etc. but then you don't need more than two transmitters to do this? Even trying to get the system to work for broadcasting a single source wirelessly to the transmitter (laptop to TV) didn't work when it was hooked up the correct way. Big pass.

Worked for a month..then added a second one and its been unreliable. I think maybe they are conflicting with each other in some way. I'm going to keep testing but while it was working without issue now its almost never working without an issue :(.
