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

I did have to fidget around with it to get it going on my new Sony TV, but now that it is up and running, it works great. Even though I have a brand new TV, the USB output was less than 1 amp, so I had to come up with a 2 amp USB power supply (at this price point, they should have included one). Luckily, my laptop did drive the transmitter. Once I had the power situation figured out, it came down to the laptop handshaking with the input. I was worried about the pairing, but apparently it was paired the whole time. I believe the key is that both units had a steady light on the button. I finally got it working by going out of the input and then back into the input. The video just came up. The video quality is great, it is smooth with no hitches or delays, and there is no discernable lag with the audio. Now that everything is in good order, it is a pleasure using this device.

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.

One of the greatest inventions for home A/V that has come down in a while. One of the reasons so many people have dropped cable is that cable companies make you get a converter box for each TV in your house, which you pay for monthly. If you cut the cord and go with a streaming service, you can stream from any TV you want. With this device, you can split from one cable box, and send a perfect picture to another TV. And it just works! Plug it in and go! This is actually my second set, and I got it so I could beam from a laptop to my portable projector to watch movies on the pool deck. I have not done that yet, but I sent from my laptop to another TV at the same time the original set was transmitting from a cable box to a different TV, and each seemed to work just fine independently with no interference. These are truly great, and unlike so many electronic devices which claim to be plug and play but arent, these actually are!

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.

Im a little torn on the price, however it is what it is and you know what youre willing to pay or not. So Ill leave that alone because in the end, it worked quite well. I didnt feel very much lag at all when using it with a projector as an extension of my desktop and it served my needs in my office perfectly. My only concern is how hot the connectors get when plugged in. It seems like they might do well to incorporate a small heatsink on the HDMI connector ends to try to combat that. It wasnt so hot I felt like it would burn me or anything, but it was still hot enough to make me think to disconnect them whenever not in use just to be safe.

SET TOP BOXES: Can get audio and video with my Android TV and ATSC Converter boxes. But, receiver will sometimes give a No signal message once or twice before stabilizing. Sometimes connection restores within a minute, other times need to unplug and replug. That seems to be either a power or WiFi problem. Good audio and video quality when working. CHROMEBOOK LAPTOP: Product displays ONLY the Chromebook background image, and plays audio. Wont display the cursor or anything on top on the background such as the browser. WINDOWS 7 LAPTOP: Will mirror the display but no audio. Image quality seems comparable to a wired connection. Didnt bother to check for lag since no audio is a deal-killer. BLU-RAY PLAYER: Video only, no audio. Both sending and receiving units get pretty hot, though sometimes only just really warm. Product description of operating principle makes no sense - Bluetooth to get network WiFi credentials, then operation via WiFi. Sender and receiver are their own P2P network. Confirmed that shutting down my home network doesnt prevent the two units from connecting. And, it makes no sense to use the home WiFi. That would just add extra latency/lag to the performance. Failure as a wireless HDMI for laptops. Glitchy for set top boxes. Basically, this product should work with any HDMI device, though its advertised as being only for laptops, PCs, and set top boxes. But, it doesnt work with Blu-ray players. Didnt check with game machine or PCs, and dont have adapters for mini- or micro-HDMI. A big disappointment.

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 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.

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!

The Wireless HDMI Transmitter and Receiver worked well for both video and sound. I was able to send 1080p Full HD video and sound at 60fps with no noticeable latency. The dongles felt a bit too flimsy and can be squeezed almost too easily. The caps needed to be attached to the units with at least a string so that they dont get misplaced. Both the transmitter and receiver MUST be powered via the micro-USB ports. Pairing was easily done by holding down the button on the transmitter.
