Up to two displays with 4096 x 2304 resolution at 60H

One display with 5120 x 2880 resolution at 60Hz MacBook Pro 2017 (13 inch) built-in-display to support highly NATIVE resolutions upto 5K with use of thunderbolt or HDMI display devices.

MacBook Pro 2017 (13 inch) supports scaled lower resolutions listed below: MacBook Pro 2017 (13 inch) has viewport size 1280 x 800 Pixels and its pixel ratio is about 2.0. and sum of actual pixels of any device is reffered to as 'Viewport'.ġ3.3' physical screen size with IPS technology and it's native resolution is 2560 x 1600 Pixels with approximately 227 PPI pixel density. A 15 inch Retina Macbook Pro has 2800x1800 (a little less than the 4k tv) but they are packed smaller and closer together on a much smaller surface area, 15 inch wide instead of 48.The sum of pixels which are displaying on a device is called as 'Screen Resolution'. For example a 3840x2160 4K TV that is 48 inches wide diagonally has about 90 pixels per inch comparable to a normal desktop monitor. Resolution is just a big 'carpet' of dots, you have a fixed amount of them and you can make the dots bigger to cover more area. You get to see the same thing as one would at 1280x800 but at much greater detail 226dpi instead of 96dpi. When you run a 13.3 at retina resolutions 2560x1800 the fonts are much much smaller and hard to look at, so OS X makes them as big as they were at 1280x800 but more detailed. Instead it just 'looks like' it does.Ī 13.3 inch screen running at 96dpi (pixels(dots) per inch) has a resolution of about 1280x800 and the 8pt font and other on screen elements are big enough for the eye to see. The Retina display doesn't actually run at 1280x800. The explanation on the Preferences panel is wrong and confusing.
