We liked
The DMP-UB900 will restore you faith in physical media. In full 4K HDR guise it offers a level of performance that will have new 4K TV owners gasping. Ultra-HD Blu-ray brings the experience of 4K digital cinema to the home, and rewards with brilliant colour fidelity, deep contrast and almost three-dimensional clarity.
We disliked
The UB900 may be fully compatible with Blu-ray and DVD, but its lack of legacy music format support could see high-end buyers waiting for the likes of Oppo to enter the 4K Blu-ray fray. Build quality is good, but the player lacks high-end heft.
Final verdict
The 4K Ultra HD Blu-ray format sets a new benchmark in picture performance, and Panasonic's DMP-UB900 is a worthy poster boy. Coupled to an HDR display, its imagery is often astonishing. It's also a great regular Blu-ray player, and a surprisingly fine CD spinner.
Factor in solid file playback support, plus 4K iterations of Netflix and Amazon Instant Video, and you have a machine that'll make your new 4K HDR TV look sensational.
