Is 4K Blu-ray worth it?

And other frequently asked Blu-ray questions


A 4K Blu-ray player is a super edition to any top-notch home theater system.

4K Ultra HD has sparked new interest in the world of Blu-ray players — and some new questions from our customers. I spoke to some of our Advisors and collected the most popular questions they hear these days.

Why 4K Blu-ray is worth it

If you have a 4K TV and you want to see its best picture, you’ll want a 4K Blu-ray player. Ultra HD Blu-ray discs can hold much more data than standard Blu-ray discs, so they can deliver full 4K resolution along with enhanced color and contrast.

4K Blu-ray produces the sharpest, most textured picture quality I’ve seen on a 4K screen. Movies with HDR (High Dynamic Range) are particularly striking – closely matching the vibe of the full theater experience.

What is our pick for "best 4K Blu-ray player of 2019"?

Panasonic DP-UB820

We recently picked a new favorite for "best high-end 4K Blu-ray player" when we updated our list for 2019: the Panasonic DP-UB820 4K Ultra HD Blu-ray player

Oppo left a huge void in this category when they stopped making their stellar UDP-203 4K Blu-ray player — our "best high-end player" for 2018. For a while, we struggled to fill this top spot with a replacement.

Then we got our hands on the Panasonic DP-UB820 4K player. It has arguably the best video processor ever available. That's right, some prefer the picture quality over the legendary Oppo!

See our full list of picks in the article "Best Blu-ray players for 2019."

What is HDR?

HDR is a breakthrough technology that drastically improves 4K picture quality by increasing the contrast range. It allows compatible TVs to display extremely bright and dark black picture content together within the same image.

Ultra HD Blu-ray movies with HDR are the current gold standard for picture quality.

4K blu-ray®

Ultra HD Blu-ray movies with HDR can really pop on a 4K TV screen.

What movies are available on Ultra HD (4K) Blu-ray?

Next Generation Home Theater keeps a pretty thorough, updated list of titles. All of the major movie studios are on board with 4K Blu-ray, so we’ll see the number of movies grow.

Will a 4K Blu-ray player play standard Blu-ray and DVD discs?


Will they look any better?

Standard 1080p pictures can be upconverted by your 4K player or Ultra HD TV. Some standard Blu-ray discs can look much smoother when upscaled for a 4K screen – but you shouldn’t expect full 4K quality.

Do I need to replace my cables to enjoy 4K Blu-ray?  

You’ll need an HDMI cable that supports HDMI v2.0.

Do I need to replace my other gear?

Whether you're connecting the player to a home theater receiver, sound bar, or directly to your TV, you'll need to make sure the inputs on your device are HDCP 2.2 compatible.

If you don’t have a 4K TV, you can still watch 4K Blu-rays on a 1080p TV, but obviously won’t get the full effect. Same thing with HDR content on a non-HDR screen—it will play, but not to its best potential.

If I mainly watch Netflix, do I need a Blu-ray player?

I stream most of the shows and movies I watch, but still think of my Blu-ray player as an essential part of my TV setup. Here are a few reasons why:

Reliability – You don’t need a strong internet or Wi-Fi connection to play a disc. A Blu-ray player ensures movie nights won’t be thwarted by problems with your network or service provider.

Picture quality - Standard Blu-ray players deliver Blu-ray discs in 1080p resolution. Since they don't require compression, discs can deliver a better picture than standard HD streaming services.

Choice – With Blu-ray players, you don't have to pick between streaming and discs. Many of them offer both

You’ll find more benefits in our Blu-ray player buying guide.

Can standard Blu-ray players play 4K Ultra HD Blu-ray discs?


Can standard Blu-ray players play DVD discs?


Can I get a region-free Blu-ray player?

No. The players we carry accept Region “A” Blu-ray discs and Region “1” DVDs.

What Blu-ray player do I need for Dolby Atmos?

All of our Blu-ray players can pass Dolby Atmos soundtracks. You’ll just need to make sure the Blu-ray disc is encoded for Atmos. Here’s a list of available movie titles.

To enjoy the immersive sound of Dolby Atmos soundtracks, you'll need a Dolby Atmos compatible home theater receiver (plus speakers). Or you could opt for a compatible sound bar. Be sure to connect using an HDMI cable, and set the Blu-ray player's output to "bitstream."

What Blu-ray player do I need for DTS:X?

The answer is similar to Atmos: All of our players can pass the soundtrack from DTS:X-encoded Blu-ray discs. Just connect via HDMI to a compatible receiver or sound bar and set the output to “bitstream.”

Do Blu-ray players make good music players?

Yes. In fact, all Blu-ray players will play Audio CDs. Most offer streaming music services like Pandora or Spotify, and many have a USB port to play digital files from a thumb drive or external hard drive.

Higher-end players are often designed with music listening in mind. They are solidly constructed, include a high-grade digital-to-analog converter (DAC), and can play high-resolution music. They accept high-res discs like SACDs or play lossless digital files like FLAC or ALAC.


HDMI is usually the best way to connect your Blu-ray player. Every Blu-ray player has an HDMI output which will pass video and audio. Here are the most common connections:

Connecting directly to a TV via HDMI

Connecting audio and video through the receiver

Alternate audio outputs

For video, HDMI is your best bet. But some players offer alternate audio outputs that may work better in your setup. In these cases, you'll connect the primary HDMI output to the TV and send the audio separately to the receiver.

Connecting video to TV and audio to the receiver  via HDMI

via optical digital

via optical digital

via stereo analog RCA

via stereo XLR

via Multichannel RCA

    Hi Alex, I've forwarded your comments to an Advisor so they can touch base with you on the specifics. But to answer your questions in general:

    (1) 4K players will play CDs

    (2) Most 4K TVs have the ability to upscale 1080p images.

    Yes Greg, I'm afraid that's true. You need a 4K Ultra HD Blu-ray player to play that disc.

    In the FAQs above the question was: Can standard Blu-ray players play 4K Ultra HD Blu-ray discs? and your answer was No. Is that true? Does that mean if I have a 4K TV, a Dolby Atmos receiver and a 4K blue-ray dvd that I can't even play it with my blue-ray (1yr old) player? Thanks.

    Question. Is there any blue ray DVD players that have 5CD capability? Or do they only come with one.

    Bob - It depends on the individual disc or movie. I don't think Blu-ray discs in general offer more or less subtitle options than DVD discs.

    Do blu-ray DVDs more than likely play English subtitles when regular DVDs do not?
