The Raspberry Pi team has updated the Raspbian operating system for the launch of the new Raspberry Pi 3 Model B+
. This new version of Raspbian improves the support of different screen resolutions (large, medium and small screens) and brings a new option for supporting high resolution screens: the Pixel Doubling
Enabling pixel doubling simply draws every pixel in the desktop as a 2×2 block of pixels on the screen, making everything exactly twice the size and resulting in a usable desktop on, for example, a MacBook Pro’s Retina display. We’ve included the option on the version of the desktop for the Pi as well, because we know that some people use their Pi with large-screen HDMI TVs.
As pixel doubling magnifies everything on the screen by a factor of two, it’s also a useful option for people with visual impairments.
