A:AnswerA player from the manufacturer will not play region 2 dvds. I actually tried one after I got the unit because the manual had some vague terminology that made it seem like it might, but the disc didn't work. Region 1 and A plays on a USA-based player.

A:AnswerHello and thank your for your question! The DP-UB820-K player supports screen mirroring. You can use a Miracast-compatible smartphone or similar device to display the screen of your phone or tablet on the TV via the player. - S
A:AnswerThe 420 doesn't support Dolby Vision while the 820 does. If you don't have a TV that supports Dolby Vision or don't care about that, then this is a cheaper option. It is apparently louder than the 820 player, though I have not personally used the 420 player to confirm it. My 820 doesn't make noise in the years that I have used it.
A:AnswerHello and thank you for your question! The DP-UB820-K has screen mirroring capabilities. It is a built-in feature and you can access it from the "Home Network" option in the "Home" menu. You would need a Miracast®-compatible smartphone or similar device to show the content on your screen. Hope this helps! - S
