What is the difference between Blu-ray and 4K picture quality on a 4K TV?

Blu-ray discs have a maximum resolution of 1920 x 1080 pixels, while 4K video has a resolution of 3840 x 2160 pixels, which is four times the number of pixels.

4K video has a higher bit depth, typically 10-bit or 12-bit, compared to Blu-ray's 8-bit, allowing for a wider range of colors and more accurate color reproduction.

Blu-ray uses the AVC (H.264) codec, while 4K video often uses the more advanced HEVC (H.265) codec, which is more efficient in compressing video data without sacrificing quality.

4K video can display a wider dynamic range, with higher peak brightness and deeper blacks, resulting in a more HDR-like experience compared to standard Blu-ray.

4K video has a higher frame rate, typically 24 or 30 frames per second, compared to Blu-ray's standard 24 frames per second, providing a smoother and more natural-looking motion.

4K TVs use advanced upscaling algorithms to enhance the resolution of Blu-ray content, but the results may not be as impressive as native 4K video.

Blu-ray discs have a maximum bitrate of 40 Mbps, while 4K video can have a bitrate of up to 100 Mbps, resulting in a higher-quality and more detailed image.

4K video can take advantage of the increased resolution to display more intricate details, such as fine textures, smaller objects, and sharper edges, compared to Blu-ray.

Blu-ray discs are limited to a maximum size of 50 GB, while 4K video can be stored on larger media, such as UHD Blu-ray discs with a capacity of up to 100 GB.

4K video can utilize advanced audio codecs like Dolby Atmos and DTS:X, providing a more immersive and dynamic sound experience compared to Blu-ray's standard audio options.

Blu-ray content is primarily mastered and distributed in the standard Rec.

709 color space, while 4K video can utilize the wider Rec.

2020 color space, allowing for a more vibrant and accurate representation of colors.
