OSDTKRU Wireless HDMI Display Dongle Adapter 4K,Streaming Media Video/Audio/File HDMI Wireless Extender ,No Delay, Streaming Video/Audio from Laptop, PC, Smartphone to HDTV Projector

While I like the concept and it was relatively easy to install any video I tried would eventually freeze. The video iteslf would keep going since the audio and the other screen proved but the visuals on the connected screen would stop entirely even did it while my cursor was moving on the screen so its not like it was an Idle thing.

Its fairly easy to use. The picture is really good. Slight lag streaming a movie from redbox but not too bad. I had such a hard time streaming to my TV from my phone before getting this unit. Happy with it for my needs.

It casts photos from my phone to the TV for the family to watch, so cool. Before using it, I was worried that its wireless would make its link unstable, but it didnt. It works great and is easy to link. If you want to get rid of wires, I recommend you to buy it.

UPDATE #1: I was able to test this with a projector. Connected it to the HDMI input and the USB port for power. My MacBook Air cast to it and played audio through the projectors speakers with no issues. YouTube videos played fine. I used to cast a PowerPoint slideshow with my laptop in the back of the room with no issues. Raised my rating from 4 to 5 stars since I was able to verify that audio works. ORIGINAL REVIEW: This is a wireless screen mirroring adapter that connects to your TV or projector via HDMI. It requires very little setup -- basically its plug-and-play, particularly if you have an iOS or macOS device. Wifi is not required. I tested this in a hotel room with a TV connected to a media center with an HDMI input. Setup was very quick, especially since a powered USB port was available right next to the HDMI port. Casting from an iPad and a MacBook Air was very simple -- as easy as selecting the device from the Screen Mirroring menu and entering the passcode displayed on the screen. Video quality was good. For some reason, audio was sporadic, but Im chalking that up to weirdness with the hotel room setup. Also note that some fairly common video streaming apps will not work, as noted in the description.

This was just what I needed to make connecting my phone to my tv so much easier. It truly is just plug and play. There are a few apps that aren’t supported, but for the most part you can screen mirror almost anything!

Depending on what you need it for, it can be great or just okay. For basic screen mirroring actions like presentations or pictures, it works great. But for more specific things such as YouTube videos from your phone or too many actions too fast, then it can lag and eventually crash. When watching a youtube video, it mirrors the actual screen versus just the video being played. Overall: 3/5 Does it work: 5/5 Worth it: 4/5 I would recommend it to those who aren’t expecting much but not for those who are expecting a lot.

I had the lap top hard HDMId into the tv and to keep getting up ... worked perfect - Can throw my phone onto the screen easily - love this ... what an easy fix .. didnt even know this existed!
