Pixel density in the 4K era
The shift to high pixel density displays that began with smartphones and tablets has spread to the world of PC monitors. 4K displays for PCs hit shelves in 2014, and understanding pixel density has become important in product selection along with screen size and resolution. Our theme is the move to high pixel density displays, including trends in the latest technology. There are currently two standards for 4K resolution, namely “DCI 4K” and “UHD 4K”. DPI (dots per inch) is the number of dots found within a 1-inch line of a scan or print. For monitors and displays, DPI is being abolished in favor of PPI (pixels per inch). While PPI is the correct term when referring to monitors and other displays, the two terms are often used interchangeably. PPI or DPI is a description of the pixel density of a screen. A higher pixel density means that more pixels are packed into every square inch of your screen. The exact point at which a higher PPI becomes undetectable is controversial. Some say that
