Hi Everyone!! I'm new to movie collection, I have some enquiries here

To my understanding, 4k UHD is region free, and all I need is a UHD player.

1. Can anyone recommend me UHD player?

2. Does PS5 have UHD player?

3. from amazon, most of the deal I found is (4k Ultra HD + Blu-Ray + Digital). As for the "digital" part, I watched youtube video that the digital movie code can only be use in certain country, does it mean in Malaysia, I can't redeem the code? Or can I vpn to that country to redeem? lol
