Topbuy Wireless HDMI Transmitter and Receiver, Designed for Laptops,PC,Plug & Play,HDMI Dongle Adapter,Support 2.4/5GHz for Streaming Video/Audio from Laptop, PC to HDTV/Projector

Successfully (?) installed and used the transmitter and receiver on my MacBook and flat screen TV. However, once we returned to normal MacBook viewing, started getting lots of panic crashes. Cant id the source of the problem, so the crashes continue...

This is super easy to use. Just plug the transmitter into the source (laptop, etc) and the receiver into the back of the TV. The receiver needs to be plugged in via a Micro USB cable (included) in order to work properly. My transmitter and receiver were already paired and immediately started to work once I plugged in the receiver. If they aren’t paired for some reason, all you have to do is push the buttons on the two parts and they will repair. Just make sure that you have a power source within range of the HDMI port on your TV. These are super easy to use and gets rid of the need for long HDMI cables. I carry a set of these in my laptop bag in case I need to cast to a TV or larger screen.

This Topbuy Wireless HDMI Transmitter and Receiver works great! It was easy to use to send streaming video to my projector. Love it!

Using this transmitter/receiver specifically to display video from a laptop to a digital projector that were using in our den. The digital video projector, for whatever reason, wouldnt work with a particular app that was the only one we could watch certain movies with. But with a ceiling-mounted projector, we also couldnt just connect it to the laptop with an HDMI cord (technically we could, but it was pointless if we could go wireless). Everything worked flawlessly. But most important of all, no lagging, unlikely with other less expensive wireless HDMI transmitter/receiver sets weve used before.

Great product. Well built easy to use. Exactly as described

DO NOT BUY! Does not work as stated. Plug-in devices are made too big to reasonably fit into HDMI ports on devices without covering adjacent ports, and only one HDMI extension plug-in cord is included. Transmitter and Receiver only intermittently register one another, and when they do the transmitter is not registered by the device its plugged into. I tried pairing them multiple times, per the instructions, but it did not fix the issue. TV just kept saying Plug and Play when the transmitter was plugged in. All-in-all, Id say this product was able to transmit for a few hours out of weeks worth of attempted usage. Bottom line is this product does not work, save your money.

I guess this works OK and clearly it’s designed for something like mobile rather than a set up in your home. It works although the transmitter and receivers get pretty warm. The problem is they plug directly into the devices so if the plug is in the back of the TV the TV body and all the electronics inside or going to do a fair job of blocking the signal. You may need an hdmi extension cord for this so you can get a clear line of sight. These smaller devices are limited because they don’t have external antennas. The other thing is the power requirements. It still uses micro USB instead of USB-C which is starting to be a real pain. And the strain of having another cable plugged in risks damaging your HDMI port. You have to be very careful about making sure that either side doesn’t put undue stress on the HDMI port. And of course you have to have a free USB handy on both sides or you won’t be able to power this device. I guess that’s inevitable although I would like to see a way to draw power from the HDMI port itself. Pin 18 on the HDMI specifications only carries .25 W but that should be enough to power a small transmitter or at the very least the receiver. But since nobody makes one yet I am guessing they have not been able to make that work efficiently.

This is a pretty simple device intended to do one function: to stream HDMI output from point A the transmitter to Point B the receiver. Theres plenty of use cases where this would be important and this device does the job, does it well, and couldnt be easier to set up. You can transfer the data up to just under 100 feet (98 feet to be precise) and that should cover most applications. You can even use an HDMI converter to use it with non-HDMI devices though you wont get as good of a performance this way. It pretty much just works--plug in the transmitter and receiver and theyll pair automatically and youre ready to roll some video. Very simple and very functional. Highly recommended!

Worked great at 1st, then after 6 weeks it kept losing connection. I have it 30 feet away and every time I turn off the monitor I have to bring it right back next to each other to pair it. Just lasted long enough to make it out of the return window....

I use this for presentations and to stream video to projectors when I want to have a family night. It works great and is easy to use. You simply plug the transmitter and receiver in and off you go. Its easy to use and works, not much else to ask for. I would definitely recommend.
