What The Term 1080p Means

Image
When shopping for a new TV or home theater component, consumers are bombarded with terminology that can be quite confusing. One confusing concept is video resolution. 1080p is an important video resolution term to understand but what does it mean? The Definition of 1080p 1080p represents 1,920 pixels displayed across a screen horizontally and 1,080 pixels down a screen vertically. The pixels are arranged in rows or lines. This means that those 1,920 pixels are arranged in vertical rows that cross the screen from left to right (or right to left if you prefer), while the 1,080 pixels are arranged in rows or lines, that go from top to bottom of the screen horizontally. 1,080 (which is referred to as the horizontal resolution - since the end of each pixel row is on the left and right edges of the screen) is where the 1080 part of the term 1080p comes from. The Total Number Of Pixels In 1080p You might think that 1,920 pixels displayed across the screen, and ...

What Is 4K Resolution? Overview and Perspective of Ultra HD

Image
4K refers to one of two high definition resolutions: 3840 x 2160 pixels or 4096 x 2160 pixels. 4K is four times the pixel resolution, or twice the line resolution (2160p), of 1080p (1920 x 1080 pixels). The other high definition resolutions in use are 720p and 1080i. 4K resolution is used in commercial digital cinema using the 4096 x 2160 option, where many films are shot or mastered in 4K by upscaling from 2K (1998 x 1080 for the 1.85:1 aspect ratio or 2048 x 858 for 2.35:1 aspect ratio). Under its two official consumer labels, Ultra HD and UHD, 4K is well established in home theater, using the 3840 x 2160 pixel option, via both a growing number of home theater receivers that have either 4K pass-through and/or 4K video upscaling capability, as well as TVs, video projectors, and source devices, such as media streamers, Ultra HD Blu-ray Players, and Blu-ray Disc players that employ 4K upscaling. In addition to Ultra HD or UHD, 4K is also referred to in profession...
