The likely culprit is the Blu-ray disc – or, rather, the film on it. It’s good, but it isn’t the outstanding picture they were expecting. It's not unknown for people to unpack their 4K Blu-ray player, set it up, pop in a disc, and then be less than delighted with the image quality. It allows much more information to be stored on the same size and type of disc. The term “Blu-ray DVD” is sometimes used but is technically incorrect. If you've generated content yourself using a less common format, you'll need to make sure it’s supported. It might work, but for best results, a direct Ethernet connection is recommended.įormat: A 4K Blu-ray player should play all of the DVDs and CDs you already own if they came from commercial sources, such as films, music, and photo collections. If you're using your player for streaming, an absolute minimum of 25 Mbps bandwidth is suggested (though that isn’t guaranteed to give faultless transmission).

WiFi: WiFi enables you to view your 4K Blu-ray content on your laptop, tablet, or smartphone, though you won't get the full 4K image benefits on most devices. Be sure you know what you're buying if you want your device to be used for streaming as well as disc playing. Some buyers who have bought players without them have been annoyed to find that these can't be downloaded and added later. If you have an existing sound system, you'll need to look into compatibility more carefully.Īpps: Streaming apps from companies like Netflix and YouTube may or may not be a feature of a particular 4K Blu-ray player. If you're starting from scratch, you can base things on your intended screen and Blu-ray player combination.
The best provide things like coaxial support, which allows for older but still high-quality audio to be used. More expensive players incorporate the latest advances. Entry-level 4K Blu-ray players offer limited, if any, options. There are too many possibilities to go into here, but Dolby Atmos is one popular solution. The suitability for use with full multi-speaker surround sound will depend on the connectivity provided. Soundbars are one example, and these are almost universally supported.

They automatically provide sound to your TV via an HDMI cable in any common audio format, but that can be dramatically enhanced with the right equipment. That may be true, but there's no readily available way to compare it and no independent standard, so it's up to you to take the manufacturer's word for it or not.Īudio: Blu-ray discs are capable of delivering cinema-quality audio. Reference quality video: This is another frequently used term intended to imply that the 4K Blu-ray player image is equal to the original film. Unlike HDR, which affects contrast, WCG increases the richness of the reds, greens, and blues that compose all screen images, resulting in a more vibrant picture.
Wide color gamut: WCG is another image-enhancement technique. HDR10 is more common, though some of the better players provide both. You must have a 4K TV with the same system to benefit. There are two competing versions available: Dolby Vision and HDR10. High dynamic range: HDR is a remarkably clever technology that can influence the brightness and contrast of every individual pixel, thus giving dazzling color and tremendous visual depth.
Here is what you should look for when choosing a 4K Blu-ray player. In real terms, 4K squeezes a staggering four times as many pixels into the same space as an HD screen, tremendously enhancing visual quality. Nevertheless, 4K has become the accepted term among consumer device manufacturers. UHD is a consumer standard (3840 x 2160p). For some reason, people settled on 4K because it's roughly 4,000 pixels wide. Strictly speaking, 4K and UHD are not exactly the same: 4K is a cinematic standard, (4096 x 2160p). Now we have 2160p (ultra-high definition, Ultra HD, or UHD), usually called 4K.

The previous big step forward was from 720p to 1080p (known as high definition or HD). It is the most recent advance in visual standards. It has a shorter wavelength than the red laser used in older players, so more information can be stored in the same amount of space. “Blu-ray” refers to the laser that reads the disc.
