2K Blu-ray refers to Blu-ray discs that have a resolution of 1920 x 1080 pixels, otherwise known as 1080p.
2K Blu-ray provides a significant step up in visual quality compared to standard definition DVDs. While 4K Ultra HD Blu-rays offer even higher resolution, 2K Blu-ray remains a popular format due to its wide availability and compatibility with a vast range of TVs and Blu-ray players.
Here's a comparison illustrating the key differences:
| Format | Resolution | Color Gamut |
|---|---|---|
| 1K DVD | 720 × 480 | 16.8 million (8-bit) |
| 2K Blu-ray | 1920 x 1080 | 16.8 million (8-bit) |
| 4K Ultra HD | 3840 × 2160 | 1.07 billion (10 bit) |
As you can see, the 2K Blu-ray format significantly increases the pixel count compared to DVD, resulting in a sharper and more detailed image. Though 4K offers even greater detail, 2K Blu-ray offers a balance between quality and accessibility.
