4K Ultra HD explained

Made for the cinema, and now available for the home,
4K Ultra HD sets new standards for picture detail.2


All display technology – be it on your TV, smartphone, tablet or PC – creates an image using a grid of ‘picture elements’ or pixels. Every pixel on a screen contributes detail to the image. The more pixels used to display an image, the more detailed the image can appear.1

The Samsung Full HD TVs we’ve enjoyed for the past few years have around two million pixels across the screen. That’s a lot, but 4K Ultra High Definition LED TV has more than eight million pixels. That’s four times the pixel number of Samsung Full HD!

With 4K UHD LED, the pixels are so small and the picture can hold so much detail that even images on very large screens can look sharp1. View 4K Ultra High Definition content on a Samsung 4K UHD or SUHD TV, and you can be amazed at the depth and nuance in what you see. Ultra HD pictures really have to be seen to be believed2.

4K Ultra HD screens can be found on Samsung SUHD and UHD models TVs

4K Ultra HD screens can be found on Samsung SUHD and UHD model TVs, with screen sizes from 40 inches on the KU6000 up to 78  inches on the premium SUHD KS9500.5

Why Samsung UHD LED TV?

Samsung 4K UHD LED technology isn’t just about watching Ultra High Definition content. The picture engine in Samsung 4K UHD and SUHD models includes powerful upscaling software designed to help improve the appearance of your existing entertainment collections; Blu-ray films can look amazing, the graphics in your favourite games can look crisp and sharp, and DVDs and Pay TV can appear detailed3.

Active Crystal Colour (KU7500 and KU7000 models) and PurColour (KU6000 models) on Samsung 4K UHD TV models helps deliver millions of colours, while Precision Black Pro technology works with UHD Dimming to constantly adjust backlight levels, increasing contrast across the images on the screen so that blacks are deep and rich, and whites are clean4.
