FULL HD OR 4K, what differences?

High Definition,  Full HD or 4K images. What are the differences?

Please find here a shema of the image quality depending on the number of pixels according to the image formats of the projectors and TV. FULL HD OR 4K, what differences? Find here proportion of an HD ready image, Full HD, UHD or 4K image.

Please forget the “HD Ready” format. All projectors and TVs with this format are considered as low definition devices, barely usable for schools or businesses. This is also the format of traditional DVDs. The more you enlarge the image, the more it will be blurry (lack of pixels).

FULL HD image:

FULL HD is the standard format for “High Definition”. With 1920 pixels wide and 1080 pixels high, the image is detailed enough to be projected on a large TV and even on a very large screen with a good projector also in FULL HD. This standard definition makes it possible to broadcast all sources, because this standard format is used for all media:  blu-ray, box, TV via TNT, etc …

UHD or 4K image:

UHD format is a simplified version for television  of 4K format. With 3840 pixels wide by 2160 pixels high, the image is very detailed and allows projection even greater . But you need sources in this format: box, blu-ray ultra HD. Indeed, the vast majority of Blu-ray programs, streaming or TNT, are only available in standard FULL HD. Only a few streaming platforms (Netflix including the subscription price, Amazon Prime Video or Youtube) now offer movies in “real” 4K. You will also find reliable 4K sources on 4K games of PS4 or Xbox, or even on Internet Box 4k (be careful you have fiber optics). If your sources are not in 4K, or if you do not have the necessary budget (3000 € for a serious 4K video projector), prefer a good FULL HD Standard image. You will be very pleasantly surprised.

Many so-called “4K” projectors are based on the ultra-fast display of FULL HD images by slightly shifting each pixel to “simulate” a 4K image. The number of pixels displayed therefore seems higher, but it is not the “true” 4K, just a simulation, that can take effect. That’s why  “real” 4K projectors are around 5000 €, while “4K simulators” are displayed from 1000 € … Like everything else, the price is not a coincidence, choose your projector with the right information .

In summary, TV or HD Ready projectors can see movies in low definition DVD format. TV and FULL HD projectors allow you to watch high-definition blu-ray movies.  4K and UHD projectors and TVs can see movies in Ultra High Definition format if you have the right sources.
