Review on Ultimate Compatibility: USB C to HDMI Adapter for MacBook, iPad, Dell, Surface & More by Brandon Addison

Returned. I didn't research properly. My Samsung Galaxy A51 does not have the right hardware to support standard high quality video output. You should find a cable that matches the Samsung Dex cable. Feel free to take the Why My Crap Won't Work courses at YouTube University for more information. Lol I've tried 2 phones: a51 and LG Q7+, both are capable but both are average quality. The Metro PCS By T-Mobile phones did not have the necessary hardware to use the unpowered adapter. I would not rate. I have to, otherwise I wouldn't be able to post this here. I hope this saves someone the time I wasted trying to figure this out. Thank you for reading.
