5K monitorA computer monitor with 2,880 lines of resolution. In 2014, Apple introduced an iMac with a 27" Retina 5K display. With a resolution of 5120x2880, it doubled the horizontal and vertical pixels of the standard 27" 2560x1440 iMac, which continued to be available in the iMac line. Also in 2014, Dell debuted its 27" 5K UltraSharp monitor.
The high pixel density renders high-resolution images beautifully, and 4K video editors can view a 4K image with room for menus, toolbars and other applications on screen at the same time.
Menus May Be Too Small
Although the resolution of 4K and 5K monitors is extremely sharp, most software has not been designed with this high pixel density in mind, and menus, toolbar text and icons can appear extremely small. Although Windows and Mac have built-in scaling for text and icons, not all menu and toolbar text may be increased to a satisfactory size until these operating systems become entirely 4K and 5K aware. Two imperfect options are available. A magnifier can be dragged around the screen, or the user can lower the screen resolution, the latter ignoring the native (highest) setting and defeating the purpose of having such a high quality monitor.
