4K Television Specifications


The 4K Television is the latest High Definition TV specification.

The simple description is:

4K TV’s have a rating of 3840 x 2160 pixels

Full HD TV’s ( the previous best so far) are the:

1080p Format

1920 x 1080p with 2,073,600 pixels per frame

Some other HD TV’s, such as the 1080i, have a lower specification, and could be one of these:

1080i Format

1920×1080i with 2,073,600 pixels per frame (1,036,800 pixels per field)
1440×1080i with 2,073,600 pixels per frame (777,600 pixels per field)

720p Format

1280×720p: with 921,600 pixels per frame

Previous Standard Definition TV’s (SD) have included these:

CGA: 320×200
VGA: 640×480
SVGA: 800×600

Frame rates can be between 24 and 60 frames per second, and would be indicated on some models such as:

1920×1080p25
1920×1080p50

It is often stated that: High-definition televisions provide a picture quality that is substantially higher than that of standard-definition television.

This may be true for HDTV Broadcasts, however, when watching a Standard Definition broadcast, if you compare against the old style CDT screens, you do have to wonder about the accuracy of that statement.

1080i v 1080p

Even on technical sites, there is some confusion about the difference between 1080i and 1080p.
Both are 1,920 x 1,080 pixel resolution and both have 2,073,600 pixels.
It is however acknowledged that 1080i and 1080p aren’t the same thing, but they are the same resolution.

1080i is 1,920×1,080 pixels, running at 30 frames per second.
1080p is 1,920×1,080 pixels, running at 60 frames per second.

What does that actually mean? It means it is technical, and my eyes probably can’t see the difference

One LAST point.

I read a comment from someone calling themselves “Rodrian Roadeye”, and it brought a smile to my face, and some commonsense reasoning. This was it:

At age 56 I am convinced that picture quality is based on compatibility with your eyeglasses.
