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

I have never been a big fan of wireless technology. Id probably still be using a corded phone if they were still available. We will dont use wireless microphones in our work. But there are times when running an HMDI cable to connect video devices is not practical. This product will get the job done and seems to be priced less than similar devices. There will be a learning curve before you can successfully connect. We are PC/Android people, so we needed to download a piece of software called Microsoft Wireless Display Adapter before the device showed up as a wireless display in our settings. I cant comment on what you do in the iOS environment. Connecting an Android phone and Chrome laptop to a Samsung TV was pretty intuitive. There is a USB source of power near the HDMI input. Connecting to my BenQ projector was a bit more challenging, since the projector lacks a USB port for power. Also, I need to tweak some projector settings to get the aspect ratio right. For our professional presentations, I probably will stick with a hard-wired connection. I dont need the added uncertainty with all the other things that can and do go wrong. But I do know of an upcoming presenation where the HDMI connection to the overhead projector is nowhere near where I need to stand. So I will try this hook-up method , rather than stringing an HDMI cable over a long distance.

Overall this works pretty well for its intended purpose, and allows me to mirror my phone, or laptop, to my TV. It took me some time to figure out how to use it, as I had to download an app on my phone to allow this device to connect, but it ultimately did work. It may be user error, but my experience is that I have to connect to this device using my wifi connection, so Im therefore losing my wifi internet connection to my phone while its in use... so it somewhat defeats the purpose by slowing down my connection... but overall not a huge deal. I have other smart TVs, and another casting device from that big G company... that seems to work easier and more seamlessly... but they were of course a lot more expensive. So for an economical option, I would say this is a good buy. Overall - recommended.

First - my comment about the description. They call it a Transmitter and Receiver pair. What you get with this is only a receiver. The transmitter is built into your laptop or portable device (cell phone or tablet). Presumably it is using Miracast or some similar wireless standard and relies on the transmitting device to connect. My one complaint is that the screen, prior to making a connection is rather cluttered in order to give help to make a connection. It is nice to have that help initially, but I wish there were a way to disable or show a less cluttered initial screen. I compared this to two other wireless capabilities I have in my home system and my conclusion is that it just might be the best of the three since I can set my LG TV input to optimize viewing. My first tests of this device were with my 2nd monitor on my PC that is actually a 22 inch 1080p Samsung TV. I was disappointed that it did not fill the screen in any of the 3 modes (Duplicate, Extend and 2nd Screen Only) from my laptop. Settings on the TV (Screen Fit) combined with using the 2nd Screen Only mode eventually solved that problem. I was unable to get a properly sized screen in either Duplicate or Extend mode. I then took the device to my 65 LG 4K TV and had pretty much the same issues. I then compared with similar capabilities built into the TV and to my Roku device. The same problems existed with those. The advantage to using this device is that I could make the changes to my LG TV necessary on the input used and they did not have any effect on my normal viewing through a Tivo cable converter, the Roku or my Bluray player. Finally, it is probably obvious that my tests were with a Windows laptop. I did also test it with my Samsung S22 phone and it worked quite well, much better than the LG capability that only showed it in a window over top of whatever was selected. What I was unable to test was the capability to use it with Apple devices. I understand that Miracast is not compatible with these. So the capability of working with Apple is a real plus, making it a more universal solution.

Connect to any HDMI TV input. For iPhone to mirror, go to control center and press mirroring icon. Select Renkchip on device list. Phone desktop shows on TV screen, then go to Youtube app or open anything on phone. Anything on phone is mirrored.

Doesnt let you go full screen with any other apps (newer video apps) other than the ones they have listed. If you try going to the full screen or play the video off any other apps, it shows black. Not worth it, if your not able to screen cast what you actually want to watch.

Some apps like Disney and Netflix won’t stream if your phone is connected

now all my video audio needs are good

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!

This was clearly made with Apple products in mind, so for them maybe it is just plug and play, but we had a difficult time figuring out how to get it to work for Windows laptops. After quite a bit of searching online we finally managed to figure it out, but initially it was so frustrating we just put it aside for awhile. Once we did get it figured out though, we started using it pretty much constantly. It works very well once you get it set up and working properly. If you run into the same trouble we did all I can say is search online for answers the same way we did. I feel like they really should have included far more information with it than was provided though, which is why I knocked off a star.
