Linux and VirtualBox on a T480s with high-resolution display

My new Thinkpad T480s has a 14” high-resolution WQHD display with a resolution of 2560 &mult; 1440 pixels. It looks great. PDF files display super crisp. Programming with lots of different panels and windows, and data analysis with large tables is so much easier than with low-resolution displays that require a lot of scrolling.
