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

What I dont like about this is the price. Think it could cost alot lower. Seen others for less but dont know how the function works for them. This does the same here on this little screen just like on my TV so it does work well. I dont know how far it will stay connected in distance but hey use a big screen wireless across the room? Cant really beat that. Especially if it is a pi. I didnt have to pair them because it already was however when turning it on ut would try to step you through a fre things so loosing the instructions is really no big deal in a way. Picture quality is just like having a cord there. I would imagine that if watching a movie there might be some kind of lag because nothing beats direct connection like wired if no lag is needed. Not saying there is but if you notice it then because if wireless there might be some. Well other than price I think these a are good. 4 stars if you know why. Good Luck just me.

It is working well with 1080p and in 60Hz/120 Motion Rate. Working well with my recently purchased non-smart small TV purchased from Amazon. If anyone have PS5 and 120Hz refresh rate TV then I will still recommend to go with wired HDMI capable of 120Hz refresh rate. But if you have you use it with for devices capable to provide 60Hz then go for this wireless HDMI, happy so far without any issue.

works great

Makes connecting laptop to tv so easy no need to move tv and mess with cables.

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.

Just plug in and go. Connects the computer to the tv. The picture was great.

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.

When it comes to technology, life just keeps getting better. My computer will cast to my smart TV, but only with some programs, not many, and it was difficult to make that work. Using a 25’ HDMI cable worked well but was a hassle. This device works as well as a cable but without the hassle and trip hazard. It is truly plug and play. The most complicated part was switching the input on the TV. The only issue I had was that one, not smart TV, that is over 10 years old, wouldn’t recognize it. It works fine on a different TV, that is also over 10 years old, and on all my newer TV’s. I noticed people wrongly complaining about the size and the fact that it’s too wide to fit next to other cables on the back of the TV. There is a pigtail included just for that purpose. It is not an issue. I’m very happy with this and it gets used a lot.

Works great to display my small laptop screen (that I dont use due to size) on my big tv. Makes my eyes happy and I can get comfortable on the sofa instead of sitting at my desk. Of course it means working with only one screen, but thats ok for some projects. Its just nice to have options. I havent noticed any lag and setup was a breeze.
