![]() ![]() ![]() You need a Dolby Vision disc, a Dolby Vision–compatible player, and a Dolby Vision–compatible display to take advantage of it. Dolby Vision, on the other hand, is supported by some streaming services and some 4K Blu-ray discs (those discs also include HDR10, though). Every HDR device, including any 4K display that’s HDR-compatible, can handle HDR10 content. ![]() To our eyes, Dolby Vision HDR content looks better than HDR10 content, but HDR10 has wider support from manufacturers and movie studios. HDR10 and Dolby Vision are the two major competing HDR standards for disc and streaming content. High dynamic range ( HDR) refers to video standards that enable higher contrast ratios-or, starker differences between light and dark areas of the screen-than prior technologies.Whereas a 1080p HDTV has 1,080 lines of resolution with 1,920 pixels in each line, 4K TVs have twice as many lines, with twice as many pixels in each line: 3840×2160 pixels. 4K or Ultra HD refers to the number of pixels in a display.That's why our reviews are trusted by retailers and manufacturers as well as consumers. We also compare 4K Blu-ray players with rival products in the same category, and the current class-leaders to see where they sit in the current market and to help us decide where they should feature in this buying guide.Īll review verdicts are agreed upon by the team as a whole rather than a single reviewer, helping to ensure consistency and avoid individual subjectivity. We'll also use the player with a more price-comparable system to see how it works with electronics and speakers that would be a better fit price-wise. To assess sound quality, we connect them up to our reference AV receiver and surround sound package so we can hear just what they're capable of. When testing picture quality we try players with reference TVs and projectors trying a wide range of content, including SDR and HDR. This includes a dedicated home cinema room where we spend plenty of time with every Blu-ray player that passes through our doors. This gives us complete control over the testing process, ensuring consistency. ![]() We have state-of-the-art testing facilities in London and Bath, where our team of expert reviewers do all our in-house testing. The What Hi-Fi? team has more than 100 years of experience in reviewing, testing and writing about consumer electronics. So how do we come to our review verdicts? And why can you trust them? Allow us to explain. Here at What Hi-Fi? we review hundreds of products every year, from TVs to speakers, headphones to hi-fi systems. Read the full review: Panasonic DP-UB9000 How we test blu-ray players The provision of a 7.1 multi-channel analogue is great news for owners of legacy AV receivers, while the choice of either balanced XLR or unbalanced RCA connections for stereo playback and the provision of support for WAV, FLAC, AIFF and AAC audio formats shows this player means business. Soundtracks are delivered with plenty of weight and power, which is just what you want from a premium player like this. There's a great sense of depth and realism to 4K images that makes you sit up and take notice. Its menu system is a little overcomplicated, but once you've got the Panasonic set up for your particular display, it serves up an entertaining and attention-grabbing image, bursting with colour. There are some great budget 4K Blu-ray players in this list, but the Panasonic DP-UB9000 is the one to audition if you're in the market for a premium machine. Each model has been through our rigorous testing process so you can be 100% confident that they all serve up brilliant pictures and sound at their respective price points. Our list of the best 4K Blu-ray players only contains models reviewed by our test team in our dedicated test rooms. Expect to find HDMI outputs as standard on modern players and, for flexibility, many Blu-ray players have an additional audio-only output. Some 4K players are also universal decks that can play more niche audio disc formats such as SACD and DVD-Audio.Īlmost all players have Ethernet ports for a wired network connection and a large number even have wireless built-in and USB ports that you can use to access an external hard drive. But you'll need to partner it with either a compatible sound system and AVR or a soundbar capable of outputting immersive audio.ĤK players are backwards compatible so you can play normal Blu-rays and DVDs without issue, though if this is something you're likely to do frequently pay close attention to a model's upscaling abilities. 4K Blu-ray players not only enhance your viewing experience, but they can also support lossless object-based surround formats such as Dolby Atmos and DTS:X. ![]()
