I plugged this into my Galaxy S20 Ultra 5G and connected an HDMI cable between this adapter and the TV screen on my Samsung flat screen TV, and immediately the phone screen was mirrored on the TV. No setup, no drivers, just immediate connection.Picture quality is great, when I watched a video on the phone, the audio and video both showed up on the TV. Rotating the phone to landscape position put the display in landscape format on the TV. Some apps on the phone don't go into full screen mode, but that's a function of the phone, not the adapter.Note that I had to go into the phone settings a while back and choose screen mirroring instead of "Samsung Dex" as far as what happens when the phone is connected to HDMI. The phone defaulted to Samsung DEX and I had to change that when using with the Samsung HDMI connector. So, since that was already set up, when I plugged in this adapter to the phone and connected it to the TV, it just mirrored the phone screen on the TV right away.This connector works just as well as the genuine Samsung HDMI connector for the Galaxy and is much cheaper in price, and is available! The Samsung branded connectors are hard to find.It appears to be of good build quality, and I certainly can't argue with the price. I might buy a spare just to have on hand in case I lose this one! I am really impressed with the quality of this connector and how well it works, the picture quality is great. It is a tiny size too, easy to toss in your suitcase along with an HDMI cable so you can plug the phone into a hotel flat screen TV HDMI connector and watch videos on your phone on the TV set at the hotel!
