Microsoft 4k Wireless Display Adapter - Black. Compatible with 4K TVs

These devices just work! Plug in to USB on the TV, plug into an available HDMI port and poof it starts to work. When you change inputs on the TV to the 4k adapter, it displays a screen that says press windows+K to connect. That is all there is.If you want to get fancy download the wireless display app from windows store. Then you can customize the background, change the password and require a rotating PIN for new devices to connect (say in corporate environment). What everyone loves is if you have a newer WIFI adapter (and network), these things do flawless streaming in 4k, with little effort. Our conference rooms are finally easy to use.Don't stop there though you can connect your Apple device, or your android phone to the TV as well and cast straight to the display. It is true that many new TVs have this built in, but it is usually a proprietary form of WiDi and doesn't play nice with all devices. This DOES.You really cannot beat these things for the price. Beats the heck out of Chromecast, or an alexa device since you can literally cast any smart device to it up to 4k.

I installed this new Microsoft 4k Wireless Display Adapter on my 4K TV and quickly paired it with my new Windows 11 desktop computer. Voila... connected! From there, as suggested by the instructions, I installed the official Microsoft 'Wireless Display Adapter' app through the Microsoft app store. Through this app I updated the adapter to the latest firmware, changed the display name and wallpaper, and even got it connected to my WiFi (as Microsoft recommended for stability). Within a few minutes I started experiencing random disconnects, which lead me to believe that I received a defective product. A momentary Google search revealed no solutions, however, I quickly learned that many others here are having the same problem. I spent significant time trying to pinpoint the problem... not only did I find the problem, but I also identified the solution. I rarely write reviews but I figured it could help countless others who are beyond frustrated with the random disconnects. The solution is to simply reset the adapter using the reset button on the device itself. Once successfully reset, it should no longer be paired with your computer. From there hit Win + K and pair with it again. I found that once it has been paired again you can use the full functionality of the Microsoft Wireless Display Adapter app WITHOUT the app requiring that the device first be connected to WiFi (changing name of device, wallpaper, etc). Bottom line, the problem is the WiFi function. I have phenomenal WiFi here so it is not on my end, I just think this device is unable to be stable over WiFi. Hope this helps... good luck!

I put this Microsoft Wireless Display adapter on my Sony Bravia SmartTV. This Sony TV which originally allowed smartview casts from Samsung phones. Then Sony firmware updates added appleTV and removed smartview cast support ~2020. The Microsoft Wireless Display adapter supports Samsung Smartview casts beautifully. My only complaint is that you must have a windows 10 PC in order to rename the Microsoft Wireless Display adapter or update the firmware. There is not a Microsoft Wireless Display adapter app for IOS, Android, MACOS or Linux to rename the Microsoft Wireless Display adapter or upgrade its firmware.

If you're in IT for a business that lets you make decisions as to what equipment the company uses in their conference rooms, definitely go for these! Typically, set up is about 5 minutes, if you include the time it takes to get behind the display and install the thing. The actual connecting and set up is about 2 minutes. They work just about as well as can be expected, about 98% up-time, with a few little networking hiccups thrown in.Set up can be a little finicky sometimes, I've had 1 of the 4 I set up, just refuse to connect to my main laptop, but using a different computer, it worked just fine. Once you get it on the network and rename it, they work flawlessly. I also really like that you can set up a Pin for first time connections, and also a password for changing settings. I've never had an issue with anyone outside the company trying to connect, but knowing they can't is a plus!

Bought the first one for a friend who was unable to afford DirecTV. Now he can stream from his to the TV using the Smartview App on his Samsung phone. Worked so well I bought one for myself. We have older phones and I believe the newer phones do not support Smartview. The Adaptor hooks to the TV via USB and HDMI and allows you to mirror what is on your phone screen without the Adaptor having to connect to the Internet. I believe it transmits through the bluetooth connection. Anyway, it works great with anything stored on your phone or if you have a good internet Connection for streaming. I bought mine directly from Microsoft.

Microsoft is always on top!!

Bought this to connect my computer wirelessly and have a second extended display without running a cable. Did not work. Spent hours trying to make it work. Then tried another laptop and it worked like magic without issue. The computer it liked (Acer nitro 5 17") had Windows 11. The computer it didn't like (Acer Nitro 5 15") had Windows 10. Same graphics card. I went down the rabbit hole of Miracast drivers. the Windows 11 machine had different drivers, but no matter what I did the drivers would not update on the Windows 10 machine. Finally I caved and updated the Windows 10 to Windows 11. After that the adapter kept prompting me to enter a bluetooth pairing pin on the adapter. This is impossible because the adapter has no way of entering anything. I connected to the other computer it likes, downloaded the Wireless Display Adapter app and made sure "PIN" was not required. Made no difference. Restarted my misbehaving computer and now the pin was no longer needed, but it still never connects. Not even once. It works great on the happy computer, but not on the one I actually want to use with it. RETURNING.
