PWAY Wireless HDMI Transmitter and Receiver, Portable Extender Cable Kit, 98Ft Sender Display Adapter Support 2.4/5GHz for Streaming Video/Audio From Laptop/PC to TV/Projector/Monitor

This is a very cool, very tiny little device that enables one to "broadcast" an HDMI signal from the "source unit" to the "display unit" wirelessly in a plug-and-play fashion. This unassuming device looks like a USB cable on one end and an HDMI cable on the other with only slightly larger than normal connector housings. Through the magic of ever-shrinking microelectronics they've been able to pack all of the control and processing power into a very tiny area. I was amazed at the quality of the broadcast signal. I had to really analyze the signal as it was displayed on my 60" HD TV in comparison to the 15.5" display on my laptop in order to see any significant differences. The only areas where I thought I might be seeing some "blurring" of the signal was in the "flying hairs" of the performers as they were singing. And that could have actually been an artifact of the way the camera depth-of-field and focus were set and not signal blurring. MORE than adequate for my uses!I did notice that there is a slight (but noticeable) time lag between what I saw on my laptop and what was displayed on the TV screen. Not surprising, and not an issue because the sound from the TV was in synch with the video!I've seen other wired ways of connecting computers to TV's over 10's to 100's of feet, but this is the first wireless one that I've seen with this kind of configuration and capability. NOT having to run wires can make a huge difference in setup times and especially for presentations or trade shows! Since I only have one of these units, I don't have any way to test if multiple units can be used with different video sources at the same time without interference. AND it MAY be possible to use an HDMI "splitter" to create multiple identical HDMI data streams for broadcast to multiple displays when using multiple pairs of these wireless HDMI transfer cables.At almost $70 it "feels expensive" because the cables are so "simple looking" but when one really considers all the costs of other "solutions" it doesn't seem nearly as expensive any more!5 Stars for a wonderfully functional device!

As others have noted there is a slight delay using this but not enough to really be an issue. I will take the small delay over having to run a physical cable across the floor anytime I want to transmit HDMI from laptop or other device to TV.

I am amazed it all fits inside normal cables! They are so light and portable. This would be a great help to those with older devices without "cast" capability. I got this to use to wirelessly connect to a second monitor from my laptop PC. It works perfectly for this purpose. It is totally plug and play with no drivers needed. Even the instructions are not really needed. There is one adapter to transmit the signal and one to receive the signal. Just plug the cables into the correct devices with USB power and it just works. I was able to have the second monitor up and running withing a minute or two. When I set the second monitor to the same resolution as my laptop (the max resolution on my old laptop is 1280x720) everything worked perfectly. I did not notice any lag at all and the colors and contrast were fine. But when I cranked the resolution on on the second monitor to 1920x1080 (the monitor's native resolution) I did notice a few small issues: 1) the display was slightly horizontally compressed with black bars on both sides when the image should have exactly filled the screen 2) the black bars on both sides had some minor flickering artifacts. The artifacts weren't too bad and did not affect usability. Since these issues may be due to the inherent limitations of my old laptop and did not impact usability I will not subtract a star. Overall it is a good product and seems to be a bargain. Five stars.

I can't say enough about this device. I purchased another brand with a similar concept and it is quite good as well come up with this one is even better. This one looks better, feels higher quality, and was incredibly easy to set up. I love that everything is labeled properly, it's very clear what you need to do. The instruction manual is simple but clear as well. The packaging was simple and clean and even reusable if I wanted to store these cables Inside the box it slides out like a little tray. Aesthetics aside, it functions perfectly I had it up and running in a little under 30 seconds. Plug the HDMI and USB into the back of my TV, plug the HDMI and USB into a dongle I have and then into my Lenovo Yoga 9i, navigate to HDMI 4 on my TV and Bam! everything's up and running. The sound was incredibly clear. The picture was on point. The refresh rate was great. Just Wow!Very enthusiastic recommended purchase.

It is so genuinely plug-and-play that I didn't need to use the instructions. The clearly labeled receiver plugged into an HDMI port on my TV. Oh, what is this USB plug? Ah, for power, for which my TV's USB port is sufficient. The transmitter, I saw right away, also needs external power.I was able to use this with my Chromebook, which doesn't have an HDMI port, but I use a USB-C to HDMI adapter, and that adapter works with this transmitter. Of course it should work fine, but you never know these days with little adapters.There is a little, little bit of delay, but really not bad if you aren't playing high-speed video. This is splendid for when you or someone needs to whip out a laptop, but a long enough HDMI cable isn't handy.
