What Is Ultra HD or UHD Resolution? A Basic Definition

“Ultra High Definition”, or “Ultra HD”, would be used for displays that have an aspect ratio of 16:9 or wider and at least one digital input capable of carrying and presenting native video at a minimum resolution of 3840 × 2160.

the Difference Between 4K vs. UHD

4K is a professional production and cinema standard. UHD is a consumer display and broadcast standard. To discover how they became so confused, let’s look at the history of the two terms.

The term “4K” originally derives from the Digital Cinema Initiatives (DCI). This consortium standardized a spec for the production and digital projection of 4K content. In this case, 4K is 4,096 by 2,160 and is exactly 4x the previous standard for digital editing and projection (2K, or 2,048 by 1,080). 4K refers to the fact that the horizontal pixel count (4,096) is roughly four thousand.

The next step up from HD is UHD, Ultra High Definition. It’s the official name for the display resolution of 1,920 by 1,080. UHD quadruples that resolution to 3,840 by 2,160. It’s not the same as the 4K resolution made above. Despite this, almost every TV or monitor you see advertised as 4K is actually UHD

Today’s laptops mostly stick to 1080p or 4K resolution. On the other hand, there are a few PC monitors that offer WUXGA, which is a nice little step up from the most common resolution of 1080p. It’s rate, but that extra screen real estate means that you’ll see more of your favorite documents and web pages without scrolling.

WUXGA stands for widescreen ultra extended graphics array and is a type of display resolution. Resolution explains how many pixels a display has in width x height format (the more pixels, the sharper the image quality). WUXGA displays have a resolution of 1920 x 1200.
