What is 4K? Explained in contrast to Full HD
4K (4K UHD) is a video standard with a resolution of 3840x2160 pixels. Compared to Full HD (1920x1080), it has twice the vertical and horizontal resolution, resulting in four times the total number of pixels.
| Standard | Resolution | Total Pixels | Features |
|---|---|---|---|
| HD (720p) | 1280x720 | Approx. 920,000 | Entry-level |
| Full HD (1080p) | 1920x1080 | Approx. 2.07 million | Current standard |
| 4K UHD | 3840x2160 | Approx. 8.29 million | High definition, suitable for large screens |
| 8K | 7680x4320 | Approx. 33.18 million | Broadcasting, professional use |
Is a 4K projector truly necessary?
Before considering purchasing a 4K projector, please check the following two points:
① Do you have an environment where you can enjoy 4K content?
To benefit from 4K, you need 4K content.
- Netflix 4K: Premium plan (1,980 yen/month) allows viewing 4K HDR content
- Amazon Prime Video 4K: Increasing number of compatible content
- YouTube 4K: Free viewing of 4K videos
- 4K Blu-ray: Requires a 4K Blu-ray player and 4K discs
② The larger the screen size, the greater the benefit of 4K
The screen size at which the difference between Full HD and 4K is visible is when the viewing distance ÷ screen size (inches) is 1.5 or less. While the detail of 4K is clearly felt on large screens of 100 inches or more, the difference may be less noticeable on screens 60 inches or smaller.
✅ 4K is suitable for those who:
- Want to watch on a large screen of 100 inches or more
- Want to enjoy Netflix 4K and YouTube 4K
- Want to prepare for the future shift to 4K content
- Are particular about image quality
💜 Full HD is sufficient for those who:
- Primarily watch on screens 80 inches or smaller
- Want to keep costs down
- Mainly watch terrestrial TV and DVDs
- Want to try out a projector first
