4K is not a scam, but bitrate and source matter most
In home cinema, 4K resolution has been sold as the definitive standard. However, a detailed analysis reveals that quality depends more on bitrate and the origin of the material than on pixels. A poorly mastered 4K Blu-ray disc can look worse than a well-treated 1080p Blu-ray. The key lies in bitrate, which determines sharpness and compression artefacts.
The resolution myth: the human eye has its limits
Several analyses agree that the human eye has a resolution equivalent to around 4K under normal viewing conditions. That is why 8K is considered a commercial and technical failure. Manufacturers such as Samsung have already acknowledged that 8K makes no sense for the average consumer. However, 4K offers a noticeable improvement over 1080p on large screens (over 55") and at short distances. For small screens, the difference is almost nil.
The importance of bitrate and the original source
Bitrate is the critical factor. A 4K video with a low bitrate can show compression and pixelation, while a 1080p with a high bitrate delivers a superior image. That is why films shot on 35mm scanned at native 4K (like Predator) look spectacular, but abusive remasters with DNR (grain removal) or AI destroy the original texture. The DVD format offers barely 0.5 megapixels, while 4K reaches 8 megapixels, a 16-fold leap. But without a good master, those pixels are empty.
HDR and Dolby Vision: the real qualitative leap
More than resolution, HDR and Dolby Vision improve dynamic range and colour pueblerino. They adjust metadata frame by frame to make the most of the TV's 16 million colours. Films like *Mad Max: Fury Road* or *Top Gun: Maverick* are examples of good use of 4K HDR. However, streaming content usually has limited bitrate, which reduces quality.
In short, 4K is not a scam, but its value depends on the source, the bitrate and the screen size. Marketing has created unrealistic expectations. The question that remains is: how long will we keep buying TVs with resolutions we cannot take advantage of?
