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.

The Wireless HDMI Transmitter and Receiver, a remarkable innovation in the realm of technology. This cutting-edge device serves as a bridge between your laptop or PC and your HDTV or projector, enabling seamless streaming of high-quality video and audio. Its wireless functionality liberates you from the shackles of cumbersome cables, providing unparalleled convenience and flexibility.

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.

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).

Pairing this with an HDMI splitter, my husband can watch satellite TV in two different rooms. hes pleased with the results.

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

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

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.
