GoKawiil4K explained: how display resolution naming evolved from 720p to Ultra HD
The article traces how display resolution terminology evolved, noting that '4K' refers to roughly 4,000 horizontal pixels while related terms like Ultra HD, 2160p, and QHD (1440p) describe similar or adjacent resolutions using different naming conventions. It also clarifies older terms like HD (720p), Full HD (1080p), and the difference between interlaced and progressive scanning.
GoKawiil's interpretation of the reporting above, not reported fact.
Understanding these naming conventions helps consumers make sense of confusing marketing language when shopping for TVs, monitors, and streaming services. It also explains why certain resolutions like 1440p are common on monitors but absent from major streaming platforms, since they aren't standardized video source formats.
- 4K and Ultra HD (UHD) are largely interchangeable but distinguished from cinema-specific 'DCI 4K'.
- 2160p, 1440p, and 1080p follow a vertical-pixel-count naming tradition, while '4K' emphasizes horizontal pixel count for marketing appeal.
- QHD/1440p sits between 1080p and 4K, mainly used in monitors rather than streaming services.
