What is Ultra HD?

With multimedia technology constantly evolving, many consumers find themselves asking “what is Ultra HD?” Ultra High Definition, also known as Ultra HD or UHD, is a standard of image resolution. The term Ultra High Definition refers specifically to an image resolution containing 3,840 pixels along the horizontal axis and 2,160 pixels along the vertical axis. This results in a picture containing 8,294,400 pixels (approximately 8 megapixels), which is four times as many as a standard high definition (1080p) image. As standard high definition is phased out, more and more content will be produced to UHD standards, or 4K resolution.

Are 4K and UHD the same thing?

You will often find the terms 4K and UHD used interchangeably, and that is because as they relate to consumer products, they are one and the same. The term 4K is derived from the width of an Ultra HD picture, which at 3,840 pixels, is nearly 4,000 in total. However, it's worth noting that 4K resolution has two standards: one for consumer products and one for cinema projection (4K DCI). The two are slightly different, and should not be confused for one another. If you see the phrase 4K used in marketing materials or language, then it is likely referring to an Ultra High Definition picture: 3,840 X 2,160 pixels.

What types of electronics use UHD?

Laptops, desktop PCs, computer monitors, and televisions with Ultra High Definition resolution are all commonly available. It is also possible to buy dedicated video cameras, action cameras, and still cameras with video capability that shoot at 4K UHD resolution. There are also a few tablets and smartphones that feature 4K Ultra HD resolution.

What types of UHD products does Lenovo offer?

For individuals seeking unparalleled clarity of picture, vibrancy of color, and fine detail, Lenovo offers several different 4K or UHD options. Lenovo's Y Series of laptops feature the astounding Ultra HD technology. The picture quality of these devices will redefine what consumers expect from a laptop experience. Desktop users find what they're looking for in the ThinkVision Monitor Series. Some of the Ultra HD LCD monitors feature an infinity glass design, touch-sensitive buttons, USB and HDMI connectivity, dual speakers, and an Energy Star 6.0 rating. These specifications will enhance any desktop computer while helping minimize environmental impact.
