The more pixels available, the larger the screen size can be. The abundance of pixels in 8K Ultra HD is what makes it possible to support large screen sizes. It measures the number of pixels in a square inch of a TV (or computer) screen - the higher the PPI, the better the image quality. The new 8K standard for TV is double that: 7680 × 4320 (over 33,000,000 pixels in total).īesides the total number of pixels, a critical spec is the pixel density, which is expressed in pixels per inch (PPI). The 4K UHD standard consists of 3840 x 2160 pixels (over 8,000,000 pixels in total), which is almost four times the number of pixels of 1080P. (The first number represents the horizontal plane and the second, the vertical.)
For example, the picture in a 1080P TV is comprised of 1920 x 1080 pixels. The more pixels in an image, the more detail it can show. The images you see are composed of thousands or sometimes millions of pixels, depending on the format of the TV you’re watching on. A Matter of DotsĪ tiny dot called a pixel is the key to understanding TV (and computer) screen image quality. Before I explain why, let’s quickly review how we define picture quality in TVs. Some manufacturers are planning to release even larger models in the near future.īut before you rush out to buy an 8K set, you may want to wait for the content and supporting gear to catch up. Currently, you can buy 8K models in screen sizes ranging from 55″ to a whopping 98″. This format was also known as “Full HD,” with “HD” standing for “High Definition.” (Older TVs offer only “SD” - short for “Standard Definition.”) Then came 4K UHD (“Ultra” HD), which until recently was the highest video resolution available.
Just ten years ago, 1080P (the “P” stands for “progressive scan”) was the industry standard. In this article, we’ll demystify some of the key terms to better inform your buying decision. But figuring out what model to buy can be confusing, thanks to an alphabet soup of technologies. Today’s televisions offer screen sizes and picture quality that greatly surpass that of previous generations.
