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

This HDMI transmitter and receiver kit works out pretty decently to not have to run long or visible cables. The setup works out pretty well for sending audio and video wirelessly to a set of video glasses, even if limited to flat out 1080p. The transmitter and receiver auto connect to each other after powered up and can auto reconnect to each other if there is a disconnect or power loss. Requires USB power to run and the cable should be decently long enough to reach most USB ports and chargers to plug in. Also comes with an HDMI extension if you need a bit more length. The main HDMI side of the cable do get noticeably hot during use, having the main body be made of aluminum with small fins could help with heat dissipation and heat management. This is for the white cable version with HDMI on one end and USB type A on the other.

I ordered this to use with a client who is doing live streaming classes via Zoom and wanted to mirror a computer to a TV screen so he could see and interact with class participants. When I opened the box and took out the transmitter, I was surprised at how very light it was. In the pictures it looked like aluminum but its actually a rather cheap-feeling plastic. I plugged the unit directly into the HDMI port of my 2022 MacBook Pro but then discovered that the unit is so wide that I couldnt plug the power cable for the unit into the USB C port beside it. I then used the HDMI extension cable to plug into my laptop. The included cable to power the transmitter/receiver has USB A on one end and micro USB on the other end...neither one of which is supported very well on modern laptops. I had to use a USB C to USB A adapter to plug into my computers USB C port. Then I plugged the USB A to micro USB cable into the adapter and transmitter unit. By this time I had quite a snarl of cords and adapters next to my laptop. I then plugged the HDMI receiver unit into my TV. I had to remove another HDMI cable to make room for the bulky receiver unit since there was only one HDMI extension cable included. I had to use a USB power bank to power the receiver since my single USB output on the TV went to my soundbar. Now I was finally ready to test it out. This part was pretty straightforward and easy. Just push the button on the transmitter and my laptop screen was mirrored to the TV. As soon as I did this, the resolution of my laptop screen got much bigger so the windows and font size reduced considerably. These smaller windows and font size were also mirrored to my TV. To test, I tried streaming a TV show from a popular streaming service onto my TV from my laptop. There was a very noticeable delay as I watched the picture on my laptop and compared it to the TV. It seemed like about a 1 second lag. The advertising says plug and play, no delay but this was not my experience. Even with my laptop just 4 feet away from my TV there was a significant delay. This wouldnt matter much if I was just streaming TV shows, but I ordered this for live online classes via Zoom. This means that there would always be a significant lag time between a class participant speaking and seeing/hearing it on the TV. This would get frustrating quickly with people trying to talk over each other, thinking the other had finished speaking. Overall, this was a disappointing experience and did not do what it was supposed to do. For this reason I cannot recommend it unless you dont care about the lag time.

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

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!

I never knew these types of HDMI cables existed for wireless displays, but they work amazing. Straightforward and to the point to instructions and they work flawlessly for me.

This HDMI Transmitter/Receiver is Plug and Play and has a great transmission distance. It transmits not only video but also audio. The examples of its applications are vast, but Ill refer to my own experience. As a university professor, a significant portion of my courses are conducted online, while others involve student gatherings. For these purposes, we rely on an audio and video system. Therefore, these modern pedagogical methods make the use of such tools essential. Personally, I used these wireless HDMI connectors to transmit from my laptop to a 100 audiovisual projector. Here, Id like to share a crucial tip that I consider vital when using them. Its important to properly connect each one (transmitter/receiver) and power them via a USB-C cable with 5V-2A. This information was not included in the manual, and I was almost frustrated because I couldnt get them to work. Even though the devices indicated a connection between them, I had no idea what magic trick to try. So, I took a deep breath. (Clarification: In my opinion, those USB-C connections were intended for charging the transmitter/receiver devices, just like a cellphone or Bluetooth headphones. But surprise! They dont charge; they simply receive power. Thats the key. I connected them to a power source using a cable with 5V-2A, and voilà, the transfer started with clear video and sound! They worked like a charm. However, dont forget that they dont charge; they simply receive power.

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.

Plug in and play is false advertisement, this product does not work..

This kit works really well especially with my projector machine. Just use my console or computer to transmit to it. Really user friendly and great value for the money.

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.
