The fact that you're here, looking for the best 4K Blu-ray player right now says something about you: you're ahead of the curve. You like owning the latest and greatest technology or, if not owning, at least knowing about the best-of-the-best upcoming tech.
And why shouldn't you? A day will come soon when everyone will want to watch their favorite TV shows and movies in an ultra crisp 3840 × 2160 resolution.
While looking at 4K Blu-ray players this early in the game makes you somewhat of a tech Nostradamus (congrats on that by the way), manufacturers don't have the same sort of passionate drive to have the latest and greatest that you do.
While most manufacturers have one or two models on the market at the moment, the list of available Ultra-HD Blu-ray players is still a fairly short list.
The good news is that while there aren't many 4K Ultra HD Blu-ray players at the moment, content for these players is growing at an exponential rate.
Netflix has started to film many of its shows in 4K high dynamic range, and Amazon has recently followed suit. The first batch of Ultra HD films have finally made their way to store shelves, too, and include The Martian, X-Men Days of Future Past and The Revenant.
But these are just the tip of the very high-resolution iceberg. Expect to see a few dozen more of these high-capacity discs make their way to an electronics retailer near you in the coming weeks and months.
One last tip before we give you our recommendations: In order to get a true 4K experience, remember that you'll need a 4K Blu-ray player, a 4K Blu-ray disc and, of course, a 4K TV in order to watch it. Don't have that last one? Check out our guide to the best 4K TV.
If you don't have a 4K TV, your 4K Blu-ray player will still work, but it will only display images in 1080p. Buy a regular Blu-ray instead of a 4K version and it will still play in 3840 × 2160 resolution, but it won't be a native 4K image and will be noticeably different than had you used an Ultra HD Blu-ray.
Enough with the caveats. Here are the the best 4K Blu-ray players in the world.
1. Panasonic DMP-UB700
The best bang for buck 4K UHD Blu-ray performance
Supported resolution: 3840 x 2160 | Smart TV: Yes | Dimensions: 430 x 61 x 199 mm | Weight: 2.3 kg | UHD Upscaling?: Yes | Wi-Fi?: Yes | 3D support?: Yes
When it comes to 4K UHD image quality, the DMP-UB700 effectively sets a new benchmark for price and performance. Streaming service support, with HDR-enabled 4K Netflix, is well worth trumpeting and the player does a swell job with 24-bit audio, be it with FLAC or DSD files. We would’ve liked universal disc support, but that’s probably not going to come until Sony launches its rival 4K disc spinner. In the meantime, though, if you haven’t got the cash to drop on Panasonic’s higher-end player, this is the UHD BRP you need to audition.

2. Oppo UDP-203
A premium player for your high-end A/V needs
Supported resolution: 3840 x 2160 | Smart TV: Oppo OS | Dimensions: 16.9 x 12.2 x 3.1 inches | Weight: 9.5 pounds | UHD Upscaling?: Yes | Wi-Fi?: Yes | 3D support?: Yes
The Oppo UDP-203 is the most expensive Blu-ray player on this list, but depending on your needs it might just be exactly what you're looking for.
The player supports a full suite of AV formats, including the niche SACD, and features a total of three HDMI ports (one for video and audio, one for audio, and another to act as an HDMI passthrough).
Unfortunately for a player that wants to offer everything the Oppo doesn't include support for streaming services such as Netflix, but if you want a premium disc player (at a premium price), this is the one for you.

3. Panasonic DMP-UB900
Panasonic's DMP-UB900 is a must-have for AV enthusiasts
Supported resolution: 3840 x 2160 | Smart TV: Panasonic OS | Dimensions: 435 x 199 x 68mm | Weight: 5.29 pounds | UHD Upscaling?: Yes | Wi-Fi?: Yes | 3D support?: Yes
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.
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.

4. Samsung UBD-K8500 4K Ultra HD Blu-ray player
4K playback on the cheap? Check out the UBD-K8500
Supported resolution: 3840 x 2160 | Smart TV: Samsung Smart Hub | Dimensions: 405 x 44.7 x 230 mm | Weight: 4.19 pounds | UHD Upscaling?: Yes | Wi-Fi?: Yes | 3D support?: Yes
The K8500 is currently the cheapest route into 4K Blu-ray. It's also a useful hub for 4K OTT services from Netflix and Amazon, and while the design is a bit Marmite, you'll be consistently impressed by its loading speed and colourful UI.
If you want your 4K HDR TV to look its best, then you can't beat 4K Blu-ray. And when it comes to sheer image fidelity, the UBD-K8500 certainly impresses.

5. Xbox One S
The Xbox One S might be primarily a video game console, but it's also a stellar (and cheap) 4K Blu-ray player
Supported resolution: 3840 x 2160 | Smart TV: New Xbox Experience | Dimensions: 17 x 11.4 x 4.4 inches | Weight: N/A | UHD Upscaling?: Yes | Wi-Fi?: Yes | 3D support?: Yes
Not holding the title of a "proper Blu-ray player" doesn't stop the Xbox One S from being a great, cheap way to play 4K Blu-ray discs. Sporting a Blu-ray disc drive and the capacity to run Netflix in 4K Ultra-HD, Microsoft's latest iteration of the Xbox is about as forward-thinking as you can get.
