In this comparison video, we test the 4K HDR10 blu ray playback capabilities of the Sony Playstation 5 using the movie Alita: Battle Angel. Specifically, we pit the PS5 up against the accomplished and well-reviewed Panasonic UB820 4K blu ray player. Is the PS5's 4K/HDR10 playback good enough? Or does it fall short? Is it worth spending hundreds of dollars on a dedicated player?
