MacOS cheats a little by squeezing in the images into the screen pixel matrix using algorithm tricks to smooth out the effect. The images the GPU is creating cannot fit cleanly onto the native display resolution they are not integer scalings of the native resolution.
The advantage is the additional real estate in the interface but it comes with a tradeoff.
In the settings, Apple offers ‘scaled’ resolution options. The more space options render at sizes even higher than 2800×1800 which simulates a larger desktop resolution, allowing it to fit more windows and UI on screen at one time. This meant that the screen would show the same content as a 1400×900 non-Retina panel … but much sharper and prettier obviously. With this setting, the GPU is rendering screen content at 2800×1800 with 1:1 integer pixel scaling. Until the latest 2016 MacBook Pro with Touch Bar, Apple shipped its 15-inch laptops at the ‘Best for Retina’ resolution. Like any Retina display, Apple ‘pretends’ that the effective screen resolution is smaller to keep buttons and interface elements fixed at a usable physical size. The 4x additional pixels are used to add fine details for sharper text, iconography and images.
I’m going to use the 15-inch MacBook Pro resolutions for the following example explanation, omitting other 2016 Mac laptops which use the same concepts at (slightly different screen resolutions and densities) for brevity. The native resolution of the 15-inch display is 2880×1800 pixels this is the physical layout of dots on the LCD. The screen resolution settings have some nuances, so firstly here’s an explanation of the differences between the different options and how Apple achieves “more space” screen resolutions in software. 2016 15-inch MacBook Pro with Touch Bar.2016 13-inch MacBook Pro with Touch Bar.This how to guide on best Retina screen resolutions applies to the following MacBook & MacBook Pro products (with slight variations on the actual pixel numbers): See a comparison, and how to change these options, after the jump …Īpple has changed up the resolution of all 2016 MacBook laptops. This setting is called ‘Looks like 1680×1050’ and offers more space at the expense of some blurriness, most noticeable on text. For the best Retina quality, you need to dig into the settings, although this will mean sacrificing some screen real estate. With a fresh install of the operating system, I noticed that my new 15-inch MacBook Pro with Touch Bar uses a scaled screen resolution that does not 1:1 map to the display’s native 2880×1800 resolution. A little-known fact about the new 2016 MacBook Pros is that Apple changed the default screen resolution configuration.
