These days we see the arrival of very high resolution displays such as Apple's retina screens and the 4K monitors. These are very cool, but for programmers they can be a real pain in the side.
Any application designed for a normal monitor will be tiny when viewed on a very high resolution monitor. Windows provides a way to make things larger on screen so that the user isn't left reaching for a magnifying glass, but the effect isn't consistently applied to all the widgets and fonts, so that the user is left with an unsatisfying and unsatisfactory result.
The programming is left with the job of cleaning this up.
