Wireless HDMI Transmitter and Receiver, Plug & Play Portable 2.4G/5G Wireless HDMI Extender Kit for Streaming Video and Audio to Monitor from Laptop/PC/TV Box/Projector

First, I've been involved in broadcast television IT for 30 years. Very familiar with video and audio setups. I've run hundreds of miles of video,, audio, HDMI cables. So I was VERY skeptical. My setup/problem: I have a Verizon Fios Cable TV box in my family room. Large screen TV wall-mounted. Since I was lazy, never got around to fishing the HDMI through the wall to the TV... so its a cable you can clearly see going from the box, up the wall, to the TV. Wife hates it. She's not wrong. In addition, we have a large-screen TV mounted in our screened-in patio. I connected an HDMI splitter to teh FIOS cable box, one HDMIL cable runs visibly up the wall to the family room TV, the second HDMI cable (75' long) is snaked under the house out to the patio and to the patio TV. I simply wanted to mirror the inside TV to the patio, primarily for football... wander in or out and the game is on. The splitter and setup works great. Along come this product. I was very skeptical. I unboxed it, Plugged the TX into my HDMI port on my laptop... the laptop provide power. The RX I connected to my office TV. The HDMI port did not provide power, so I used the provided USB-C cable to connect power to the RX. Before I could get back to my laptop... the devices sync'd and my laptop was on the TV (seconds). Did some testing, including sports and YouTube high quality videos and concerts... flawless. Micro-second delay between the laptop and TV... but no lip sync issues... audio was perfect, as was the transmitted picture. Testing passed with flying colors. Onto the family room/patio resolution. I plugged the receiver into the TV's HDMI port, it provided power! I disconnected the HDMI cable that runs to the wall-mounted TV from the splitter... and plugged in the transmitter. It lit up, we had power! The TV indicated it was waiting for connection, but nothing happened. So I simplified. Removed the HDMI splitter altogether... plugged the TX directly into the Verizon bow. Same issue. Then it dawned on me... any time I've had TV issues, it always comes back to the Verizon boxes! So I connected USB power directly to the TX... and it instantly connected to the RX... and we were working perfectly! Point is... their box apparently provided enough power for the TX to light up... but not enough to transmit. I moved the TX back to the splitter (with external USB power still connected) and reconnected the splitter to the FIOS box. It worked perfect. I then reconnected the patio TV hard-wired HDMI cable to the splitter... and everything works great! Any the cable in the family room is gone and I'm a hero! This thing really is amazing! 12 stars out of 10!! Just be aware of the power issue I ran into! Mike

I purchased this Wireless HDMI Transmitter and Receiver Kit to mirror my laptop screen to a projector across the room without running long HDMI cables—and it has delivered exactly what I needed. Setup was truly plug & play. I connected the transmitter to my laptop and the receiver to my projector, powered both up via USB, and within about 15 seconds the signal was live. No drivers, no apps, no hassle. The video quality is surprisingly good. I tested both 1080p and 720p video streaming, and there was no noticeable lag when watching movies or doing presentations. The 5GHz band really helps with stable transmission—though you’ll get the best results when both devices are in line of sight or within a reasonable range. Audio is also transmitted cleanly, with no dropouts or sync issues. This is perfect for streaming Netflix, YouTube, or giving PowerPoint presentations without any annoying delay. Overall, this wireless HDMI extender saved me from running long cables across my office and has been rock-solid for meetings and home use.

This HDMI wireless transmitter is super handy and saves me from dealing with long messy cables. Setup was really simple, just plug it in and it connected right away. The picture quality is clear, and the sound stays in sync, which makes it great for watching movies, streaming mostly for me. The range is solid too, and it even worked fine through a wall without heating up or lagging. For gaming, there’s a tiny bit of delay, so it’s not perfect for fast-paced play, but for everything else it works really well. Overall, a convenient and reliable device that makes life a lot easier.

This is the second wireless HDMI transmitter and receiver I’ve purchased for a non-profit organization, and I couldn’t be more satisfied. The first unit has been running flawlessly for over a year, providing a stable and high-quality connection without any interruptions. Given its reliability, I confidently invested in a second unit, and it has lived up to expectations. Setup is straightforward, and the signal strength remains consistently strong, even in larger spaces. The video and audio transmission are crisp and lag-free, making it perfect for presentations, streaming, and various applications where a wired connection isn’t feasible. If you need a dependable wireless HDMI solution, this one is a fantastic choice!

work well and very easy to use

This wireless HDMI transmitter and receiver has greatly enhanced my work efficiency. No wiring required. Plug and play. Connect the projector and the laptop in an instant. The picture is clear and smooth without any lag. All colleagues were full of praise. It was such a great enjoyment.

I have used this 3 times now. The first two times I have used it, it worked great. It was compatable with my old garage tv and the instructions were very easy to use. I am streaming my desktop monitor to my garage tv for a second monitor for my golf simulator and the streaming compatibility seems to be fine. The quality of the box it came is was good and I have not noticed any heat from the units. I did run into an issue last night where I was getting a disconnect icon on the tv and couldn't figure out how to fix it. I will try again and see. Other than that, I have had no issues with this device.

As others have said...it just plain works. It's so nice to get a product that you just plug it in, and it's up and running. You plug one end into an HDMI port on the TV, and plug in the power. Then repeat the same steps on the PC...that's it. Beautiful color and zero delay...thoroughly impressed!

This wireless HDMI transmitter works really well! Just plug it in and it connects right away. The screen casting is stable with no lag, and the delay is very low. It’s compact and well-made, easy to carry around. Definitely worth the price, very satisfied!

I set up a tv with built in dvd player in the master bathroom so we could watch while soaking in the jacuzzi. I wanted to be able to watch live tv too, so decided to get this HDMI transmitter and receiver combo so that I could stream from the rogers box connected to the bedroom tv. I used an HDMI splitter connected to the transmitter and connected the receiver to the tv in the bathroom (the distance is about 20-30 ft. The set up works great, it was truly plug and play, very easy to set up. The picture and sound streams perfectly. Very little if any lag in the transmission. Overall very happy with this HDMI transmitter / receiver combo !

At first, I plugged the RX and TX the wrong way and the receiver didn’t light up on my TV. Later I realized it simply wasn’t getting USB power, even though it was plugged into the HDMI port. Once I connected the power correctly, my TV displayed my PC screen instantly. The whole setup is truly plug-and-play, and the streaming is super smooth — I can watch my shows seamlessly without any cables across the room. I also plan to use this Wireless HDMI Transmitter and Receiver for my presentations in places where Wi-Fi isn’t available

FYI - You need to connect power to both sender and receiver. They lights up without the external USB power, when they are inserted into the laptop and monitor, but they wont connect to each other without the extra power. There is an almost non-detectable, split second delay when moving the mouse around the receiver screen. I don't really notice it other than when intentionally comparing response time to the laptop screen and external screen - so it's really not an issue for my application of a second laptop screen. They are bulky. The transmitter in the laptop blocks the neighbouring USB port. The one in the monitor also sort of blocks the USB port beside it, but the mini HDMI adapter is being used there, so there is just enough room to use that port for the extra power source. All in all - it's good - it gives me the wireless freedom I need for my application. I didn't know what to expect, so I was happy that it just worked as I had hoped.

Very convenient and easy to use. True plug and play setup with a stable connection. No more long HDMI cables during meetings — you can present directly from your laptop without standing next to the TV. Makes presentations much more comfortable and professional.
