TV Screen Resolutions – 720P, 1080i, 1080P, 4K, 8K

TV screen “resolution” always refers to the total number of pixels that make up the picture on the TV screen. The higher the screen resolution, the more detail the picture can produce. Today’s TVs have from a few hundred thousand pixels to 33 million pixels on a screen. One pixel = one tiny dot on the screen.

We will list the different TV types, TV resolutions, specifications, and the total pixels for each.


480p Resolution TV = 720 x 480 progressive scan. (Total pixels = 345,600)

576p Resolution TV = 720 x 576 progressive scan. (Total pixels = 414,720)


720p Resolution TV = 1280 x 720 progressive scan. (Total pixels = 921,600)

1080i Resolution TV = 1920 x 1080 split into 2 interlaced fields of 540 lines. (Total pixels = 2,073,600)

1080p Resolution TV = 1920 x 1080 progressive scan. (Total pixels = 2,073,600)


4K Resolution TV = 3840 x 2160 progressive scan. (Total pixels = 8,294,400)

8K Resolution TV = 7680 x 4320 progressive scan. (Total pixels = 33,177,600)

A higher resolution usually means a better TV. However the resolution is not the only factor involved in picture quality. Factors such as contrast ratio, size of screen, and how close you are to the actual screen are very important.

TV Screen Contrast Ratio

TV contrast ratio is defined as the ratio of the luminance of the brightest color (white) to that of the darkest color (black). This is the luminance ratio that the TV is capable of producing. A higher contrast ratio is a desired aspect of any TV.

TV Screen Size

A larger TV screen will give you much more viewing area. A typical 65″ inch HDTV screen has about 40 percent more viewing area than a 55″ inch HDTV screen. Remember that TV screen sizes are measured diagonally and not horizontally across the TV screen.

Best Viewing Distance For 4K TVs

40 inch 4K HDTV screen sit 3.2 feet to 5.1 feet away
50 inch 4K HDTV screen sit 4.2 feet to 6.2 feet away
55 inch 4K HDTV screen sit 4.5 feet to 6.9 feet away
60 inch 4K HDTV screen sit 5.0 feet to 7.5 feet away
65 inch 4K HDTV screen sit 5.4 feet to 8.1 feet away
70 inch 4K HDTV screen sit 5.8 feet to 8.8 feet away

Question: Is 720 High Definition?
Answer: A 720p HDTV has 720 lines of pixels and is considered high definition but lower than today’s standard.

Question: Can you notice the difference between a 720p TV and a 1080p TV if sitting 10 feet away?
Answer: If you are sitting more than 8 feet away from a TV screen, chances are you won’t be able to tell the difference between 720 and 1080.

Question: The cable box gives me the option to choose 720p or 1080i, does it matter what I set it to?
Answer: It is better to set the cable box the the higher resolution setting, use 1080i over 720p.

Question: My Playstation gives me the option to set the resolution, is 1080p better than 1080i?
Answer: If you have a 1080 HDTV, set your Playstation to use the 1080p as it should look better on the screen than 1080i.

Question: Will a Blu-Ray Disc played on a 720p screen look as good as on a 1080p since it is blu-ray?

  1. I understand that the pixel size is defined by the number of pixels verses the size of screen they are applied to.

    What is the smallest pixel size (in micron I presume) available currently? I guess this would be the high resolution on the smallest commercial screen? I am just interested in the range between the smallest and largest individual pixel sizes currently used. Presumably there is a manufacturing limitation in size?
