High resolution displays may require specific settings to achieve readability of text and other screen objects. High-end laptop screens and other ultra-high resolution displays may have high pixel density in a small form factor. They are commonly referred to as HiDPI (High Dots Per Inch), 4K, UHD, WQHD, QHD, or 1440p displays. Some laptops with these types of screens include MacBooks with “Retina Display”, Dell XPS 13, and ThinkPad X1 Carbon. 4K and 8K UHD TVs may also require customization to make text readable at the viewing distances typical of these displays.
To improve the visibility of text and objects on these large resolution displays, you can make the following changes.
Open the Appearance settings dialog, change to the Settings tab, and change Window Scaling to ‘2x’.
Open the Window Manager settings dialog and in the Style tab, change to a HiDPI theme like ‘Default-hdpi’ or ‘Default-xhdpi’.
