What is 4K & 8K?

Plain and simple, outstanding picture quality is the result of high resolution delivered by a television set where resolution equals to the total number of pixels per square inch (PPI) in a picture. Therefore, a greater amount of pixels provides a much better picture quality compared to one that contains lower amount of pixels.

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, but you probably didn’t even notice – DigitalTrends.com
  • The equation is simple more pixels = more picture details

Whether it is a television, a tablet, or a smartphone, more pixels mean more detailed picture. The main concept is a screen where the pixel is invisible to the naked eye. A good example is Apple’s “Retina” display or the Curved 4K Ultra High Definition models — the best way to experience 4K is to stand right in front of  a 4K HDTV to look for any pixels at all. Because the picture is so sharp and clear, you can have a seat closer to an 4K HDTV to add even more of an immersive effect.

What distance is recommended  from 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 normally sit to watch HDTV however doing so really transforms the experience to a vivid adventure — All the screen surface completely 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 un-mistakenly intensify this feeling of immersion.

Content or Compatibility Problems Again with 4k HDTV?

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 completely compatible with all your existent video components. If up-conversion would 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.

4K TVs with Big Screens?

1080p resolution looks fine on screens 50″ or less because from a typical viewing distance you won’t notice the screen’s grid of pixels. But a 55″ or  larger screens benefit from a much higher pixel count, making the pixel grid virtually invisible. 4K HDTVs not only offers a more detailed picture, but also allows you to sit closer to a screen and/or view a larger screen while enjoying unprecedented clarity.

4K with Full LED Backlighting – See to Believe It!

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 a 8K TV is approximately 8,000 pixels
  • The equation gets simpler more pixels the better picture details shown on the screen

Do All Those Extra Pixels Matter in a 8k HDTV?

Short and simple, absolutely, yes! HDTVs gave you two mega pixel image (2MP) now imaging how  a 33 MP image looks like.  33,177,600 pixels to be exact!

8K Content?

Think about this: Tokyo olympics will be broadcasted in 8K HDTV thats only 3 years away from now (2017) 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, look online for a tv mounting service near me and get your 4K or 8K HDTV mounted on the wall. Then just sit on your favorite recliner, stretch your legs, turn on your sound system to set the right mood grab the popcorn and enjoy movies and visual content like never before thanks to advances in technology. 8K HDTV is completely inevitable – it is already here!
