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.
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 the optimal pixel density is somewhere around 400 ppi, while others say that the eye-catching pixel density is closer to 1000 ppi. Since this is a matter of personal preference, it is always better to test a monitor yourself before deciding on a display.
As the screen resolution continues to grow, pixel density is a new element that should be considered when choosing a display today. Pixel density in displays is a specification that indicates the level of resolution, and the value is usually given in "pixels per inch".
