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

I got this to avoid using an HDMI cable at events where we needed a portable scoreboard, and with my projector and portable screen this was a no-brainer to put that scoreboard closer to the guests who came to the roller derby bout. Connecting is a no-brainer as the transmitter and receiver are paired at the factory. I do wish my laptop had more old-style USB-A ports to connect this with, but I used an old phone charger to supply the necessary power to the transmitter and I was up and running. The resolution is great (looks crystal clear to me, so likely is the full 4k they claim) and within the distance claimed I had no problems connecting. There is a bit of lag between when I move my mouse and when it moves on the screen, but its nothing I cant work through. I had not expected audio to transmit as well as video, but when I broadcast some videos from my laptop onto my TV the sound was definitely coming from the TV (which means no more HDMI cables on movie nights - YAY!). For what this does, I am blown away by how well it works and how simple it is to use - this is MUCH better than any Chromecast Ive ever used as I get to control what I cast and it doesnt have to be in a web browser.

I did have to fidget around with it to get it going on my new Sony TV, but now that it is up and running, it works great. Even though I have a brand new TV, the USB output was less than 1 amp, so I had to come up with a 2 amp USB power supply (at this price point, they should have included one). Luckily, my laptop did drive the transmitter. Once I had the power situation figured out, it came down to the laptop handshaking with the input. I was worried about the pairing, but apparently it was paired the whole time. I believe the key is that both units had a steady light on the button. I finally got it working by going out of the input and then back into the input. The video just came up. The video quality is great, it is smooth with no hitches or delays, and there is no discernable lag with the audio. Now that everything is in good order, it is a pleasure using this device.

Im a little torn on the price, however it is what it is and you know what youre willing to pay or not. So Ill leave that alone because in the end, it worked quite well. I didnt feel very much lag at all when using it with a projector as an extension of my desktop and it served my needs in my office perfectly. My only concern is how hot the connectors get when plugged in. It seems like they might do well to incorporate a small heatsink on the HDMI connector ends to try to combat that. It wasnt so hot I felt like it would burn me or anything, but it was still hot enough to make me think to disconnect them whenever not in use just to be safe.

The Wireless HDMI Transmitter and Receiver worked well for both video and sound. I was able to send 1080p Full HD video and sound at 60fps with no noticeable latency. The dongles felt a bit too flimsy and can be squeezed almost too easily. The caps needed to be attached to the units with at least a string so that they dont get misplaced. Both the transmitter and receiver MUST be powered via the micro-USB ports. Pairing was easily done by holding down the button on the transmitter.

Im so glad Ill never have to worry about having the correct length HDMI cable again, or tripping over a cable stretching across a room. This works and works well. Connection was as easy as plugging in both ends and waiting a minute for it to self-connect. Picture quality is good on 1080 and 720 screens, and theres virtually no lag. I tested this with a laptop and several Samsung devices as senders and a projector and several monitors as receivers. All of the connections were easy and stable. Im not sure on the power requirement, but I was able to plug the power end into my projectors built in USB port for power. Idk if its meant to, but I noticed the HDMI plug-end gets hot during extended use (several hours or more).

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.

One of the greatest inventions for home A/V that has come down in a while. One of the reasons so many people have dropped cable is that cable companies make you get a converter box for each TV in your house, which you pay for monthly. If you cut the cord and go with a streaming service, you can stream from any TV you want. With this device, you can split from one cable box, and send a perfect picture to another TV. And it just works! Plug it in and go! This is actually my second set, and I got it so I could beam from a laptop to my portable projector to watch movies on the pool deck. I have not done that yet, but I sent from my laptop to another TV at the same time the original set was transmitting from a cable box to a different TV, and each seemed to work just fine independently with no interference. These are truly great, and unlike so many electronic devices which claim to be plug and play but arent, these actually are!

You couldnt ask for a simpler devices to to get you to put the views your screen on other electronics such as your television. The picture quality is excellent. The sound is excellent. Like I said, really simple to move around and use got excellent range. Im very happy with them

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 is a great little device that you will use a lot. There was virtually no setup - I plugged the transmitter into my laptops HDMI port and the receiver into the TV HDMI port and, in no time, I was mirroring my laptop stream to the large tv monitor. This is really convenient when showing movies from my DVD drive or those I ripped to a hard drive. It is also great for presentations at meetings. This is a must have for any videophile that does serious streaming to a tv or monitor. Also, it comes at a really good price so it makes a nice gift.
