I have this to connect my Note 10+ directly to the TV I have over my treadmill for a better experience , when I use zwift to run. I used to mirror my screen on a Chromecast, but after a while there was a lag in the display between the phone and the TV and it got annoying. After application there were no problems. It activates the Dex feature on the phone, which I've played around with a bit, but so far so good
