What Is 5K Resolution? A Basic Definition

27-inch iMac with 5K display

5K describes a display resolution of 5120 x 2880. Resolution explains how many pixels a display has in length x width format (the more, the better when choosing a PC monitor).

Few monitors actually have this resolution today, though Apple's 27-inch iMac offers it. LG's 27-inch Ultrafine 5K monitor also outputs at 5120 x 2880. Few games benefit from running at this high of a resolution. Unless you're a graphics professional, you can probably be satisfied with a lower resolution screen.

    5K is the industry's latest way of unburdening the impatient of their money; and fostering the mentality of continual and frequent upgrades, just to "keep up with the Joneses"...
