What is 4K & 8K?
The answer to “what’s 4K and 8K” is straightforward. Both of them are resolutions that provide outstanding picture quality.
These are the result of high resolution delivered by a tv where resolution equals the total number of pixels per square inch (PPI) in a picture.
Therefore, a more significant amount of pixels provides a much better picture quality compared to one that contains a lower amount of pixels. Add this factor for example to a TV mounted over a fireplace and the result is superb!
4K HDTV facts
- 4K HDTV provides four times (4X) the picture resolution of a regular HD (High Definition) TV.
- The horizontal picture resolution of a 4K TV is approximately 4,000 pixels
- 4K is already playing at a theater near you
- The equation is simple more pixels = more picture details
Whether it is a television, a tablet, or a smartphone, more pixels mean a more detailed picture.
The central concept is a screen where the pixel is invisible to the naked eye.
A good example is Apple's Pro Display XDR or the curved 4K ultra-high-definition televisions.
The best way to experience 4K is to stand in front of a 4K HDTV and look for any pixels.
Because the picture is so sharp and clear, you can have a seat closer to a 4K HDTV to add even more of an immersive effect.
What distance is recommended between the human eye and a 4K TV screen?
Most scientists say sitting 1 to 1 and 1/2 times the total screen height, versus 3x times the screen height for a 1080p HDTV.
That is closer than most people usually sit to watch HDTVÂ however doing so transforms the experience to a vivid adventure
All the screen surface fills your field of vision, making you feel like you are in the scene.
Add to this appropriate room lighting and a Dolby surround sound system to intensify this feeling of immersion un-mistakenly.
Content or compatibility problems
All 4K HDTVs come with built-in features such as 4K up-conversion/scaling, which takes the video signals and fills the 4-times greater pixel count of the 4K screen thanks to processing enhancements that make a 4K HUTV utterly compatible with all your existent video components.
If up-conversion did not exist, a 1080p Blu-ray signal would appear as a small rectangular image at the center of the screen, with black bars on all sides.
Big TVs in 4K & 8K
1080p resolution looks fine on screens 50" or less because of an average viewing distance. You won't notice the screen's grid of pixels.
But 55" or larger screens benefit from a much higher pixel count, making the pixel grid virtually invisible.
4K HDTVs not only offer a more detailed picture but also allow you to sit closer to a screen and view a larger screen while enjoying unprecedented clarity.
4K & 8K with full LED backlighting
After LG launched the world's first 4K Ultra HD TV late in 2012. Now their first 2nd-generation 4K HDTVs are here, with even better picture quality than the one from 4k HDTVs.
In addition to 4K pixel power, these 4K TVs use backlighting called NANO Full LED full-array backlight with local dimming.
8K HDTV facts
- 8K HDTV provides four times (4x) the picture resolution of a 4K HDTV.
- The horizontal picture resolution of an 8K TV is approximately 8,000 pixels
- The equation gets simpler more pixels the better picture details shown on the screen

Get extra pixels in 8k HDTV
Short and simple, absolutely, yes! HDTVs gave you a two-megapixel image (2MP), now imagine how a 33-MP image displays.
Thirty-three million one hundred seventy-seven thousand six hundred pixels to be exact!
8K content
Think about this: Tokyo Olympics was broadcasted on 8K HDTV that's in 2019. Also, VR (Virtual Reality) already uses 8K resolution.
A new 4K and 8K era
The era of 4K Ultra High Definition is already here to stay. Sit on your favorite recliner, stretch your legs, turn on your sound system to set the right mood to grab the popcorn, and enjoy movies and visual content like never before thanks to advances in technology.
8K HDTV is ultimately inevitable - it is already here!
