Screens and resolutions

The transition to high-density pixel displays that began with smartphones and tablets has spread to the computer monitors. 4K PC screens appeared in 2014, and understanding pixel density has become important when choosing a product, along with screen size and resolution. Our topic is the transition to high pixel density screens, including trends in the latest technology. There are two standards for 4K resolution, “DCI 4K” and “UHD 4K”.

High-density monitors or Retina monitors sold by Apple are generally recognized as having a physical pixel density greater than 200 pixels per inch (PPI). This means that they have twice the pixel density of a high-resolution computer monitor. Smartphones and tablets are the main drivers for this trend due to their low cost and high pixel density, which is usually higher than 250 PPI. This means that the average person cannot see individual pixels on a high-density screen, 10-15 inches away on a smartphone or tablet, or 20+ inches on a laptop or computer screen.

DCI 4K has twice the screen resolution of 2048 x 1080 pixels on projectors (4096 x 2160 / approx. 17: 9) and is the 4K industry's 4K resolution. UHD 4K (also called UHDTV 4K), on the other hand, is the 4K resolution of the television industry, which was defined by the International Telecommunication Union (ITU). It has twice the horizontal resolution of 1920 x 1080 pixels Full HD (3840 x 2160/16: 9).

Since the second half of the 2000s, square screens with 5: 4 and 4: 3 image formats have been in decline in the PC screen market, while 16: 9 and 16:10 widescreen screens are on the rise and becoming too established. At the same time, there was a shift from square 17 "and 19" screens to 23 "and 24" widescreen screens. There is also an active trend for 27 "or larger widescreen displays for even more comfortable environments. This transition is split between those looking for a larger workspace, 3840 x 2160 pixels (UHD 4K) or 2560 x 1440 Pixel select ( WQHD), and those looking for a screen with better visibility at a lower price, choose 1920 x 1080 pixels (Full HD). In recent years, ultra-wide screen products with even wider screens have also hit the shelves. These are super wide screen products with a 21: 9 aspect ratio.
