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

Tested with phone and laptop transmitting to TV. Image quality was good and no visible lag. Tested distance to about 20ft with no issues.

Wireless HDMI provide 1080P 30 frame resolution, good enough for slides representation

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.

This is much more convenient than the other wireless HDMI transmitter/receiver kit that I have to use separate power wart. It works very well with most of my TVs, except for the very old one that doesnt have a USB port to power this. Theres a short delay, about 1/4 of a second, from the source laptop to the TV. Its only noticeable when I have audio output on the laptop while watching the TV. The lips doesnt sync. This is an issue when I output audio from laptop to the stereo amp. The way to remediate this is to take the audio output from the TV to the amp; that way the video and audio are in sync.

I am using this product to replace a long HDMI cable between my laptop and an HDMI projector. This lets me watch online movies projected onto a larger screen on a wall, and do so without worrying about tripping over a long cable. The wireless HDMI link is working great, and I love this product! Initially, however, I ran into an intermittent - but major - problem of sometimes getting black blank screen where an online movie - such as Amazon Prime movies and certain YouTube movies - should be showing. (But I was able to resolve this issue, as explained below.) INTERMITTENT PROBLEM - BLANK SCREEN FOR ONLINE MOVIES: As mentioned, this problem manifests itself as a black blank screen where an online movie should have been displayed. And I immediately knew this issue was related to HDCP. (NOTE: HDCP = High-Bandwidth Digital Content Protection. Not to be confused with HDMI, which is High-Definition Multimedia Interface.) From the sellers product description, my understanding is that this wireless HDMI dongle pair does support HDCP. (Without the HDCP, online movies cannot be transmitted via HDMI; this results in a black blank screen I was intermittently seeing.) So on paper, I shouldnt have any problem sending online movies from my laptop to the HDMI projector over the wireless link using this product, functionally replacing a physical HDMI cable. But in practice, at least based on my experience, the wireless transmission of HDCP seemed glitchy. I would often see a blank movie screen soon after I set up the wireless dongle pair. This was not too bad, as I could usually resolve it by simply trying again or waiting a little. But even after I start watching an online movie successfully, the blank black screen would return intermittently and unpredictably, usually 20~40 seconds at a time. This was very annoying especially in the middle of a movie. Note that this blank screen was happening only with protected movie contents involving HDCP, such as major motion pictures. I didnt experience any issues when watching non-protected YouTube videos or for just projecting a regular laptop screen / power point presentation, etc. THE SOLUTION: I read on the Internet that it is possible to strip HDCP data by placing an HDMI splitter in the HDMI signal chain, in order to resolve issues related to HDCP. So I tried an HDMI switch/splitter box I had on hand (ASIN: B09MJ176NR), and placed it in between the laptop and the transmitter dongle in the HDMI signal chain. And this worked like a charm! No more blank screen, and now I can reliably watch any online contents using the HDMI projector. ADDITIONAL TIPS: As is described in the instruction manual, the HDMI dongles (the transmitter and receiver) may require 5V DC power supplied through a micro USB port found on each dongle. For more wireless convenience, I am currently using a large USB power bank, placed on top of the HDMI projector, to power the HDMI receiver dongle plugged into the back of the projector. On the transmitter side, I discovered that extra power may not be required for the transmitter dongle when it is plugged into the HDMI splitter box (being used for stripping HDCP data, as explained above.) Apparently, the HDMI port could supply enough power, at least when plugged into the splitter box. (Your mileage may vary, depending on the specific connected device.) CONCLUSION The glitchy HDCP data transmission resulting in blank screens for online movies (doesnt affect non-protected digital contents) is unfortunate, even though I was able to resolve it by adding an HDMI splitter box. With that issue resolved, I couldnt be happier with the wireless convenience this product provides. So overall I am rating this product 4 stars, deducting one star for the intermittent blank screen issue that happens when transmitting protected digital contents (eg., online movies.) I still do recommend this (or a similar) product, because I find the wireless HDMI link so convenient. But if your use case involves protected contents sent over the wireless HDMI link, be ready to add an HDMI splitter box to resolve the intermittent blank screen issue you too may experience.

I use these to hook a computer up to a monitor for testing and initially they worked right out of the box without any kind of setup or configuration. After that is a different story. When I disconnected the receiver from the monitor and connected it to a TV I can never get them to display a picture again. I went through all the steps to resync the transmitter and receiver for the instructions to no avail. Im not sure what the issue is but after half an hour of messing around with them I gave up and decided it wasnt worth my time. Something like this just should work without having to fiddle around with it each and every time you want to use it.

Ive been begging for years hoping a wireless HDMI would someday exist and seeing this product go live I jumped at the sight to try it out. It was so easy to set up that literally anybody could pick it up and know exactly what to do. The hdmis are labeled so it was barely even a few minutes to set up to see literal magic before my eyes. I was actually blown away with how far technology has come and will be looking into buying more!

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 very easy to use HD antenna set that includes one dedicated transmitter and one dedicated receiver (and they’re each clearly labeled). It’s pretty much just plug and play since each end instantly recognizes the other and connects (though you may have to attach the included USB power supplies to them to get them to work). The picture quality is basic 1080p so don’t expect to be able to stream 4K content with these, but they’re a great option for work-related presentations or projectors that only offer 1080p resolution anyway. Overall, this is a well made and easy to use pair of basic HD antennas that sells for a pretty fair price. Four stars.

I dont know about you, but when I saw the picture, I had absolutely no faith this would work well. Just a cable with two connections? How could that work? So, it actually has two cables. One is for output and one is for input (self explanatory.) It is powered by USB. So I used my computer out HDMI and USB (A) for power. Plugged the second cable into my TV about 40 feet away, HDMI in and USB for power. That was it. It worked perfectly. The directions are basically non-existent, but who needs them!? Nothing to this. It does comes with a black HDMI extender, but that is necessary only if you need more cable length so you can reach the HDMI port or the USB port. Nothing special. Overall, works fine in the distance I tried. I am going to try a more complicated use in the next few weeks and will update if there is any change, but I am 100% convinced and a believer. This is way too easy! I hope this review was helpful!
