Apple were the first to bring super high pixel density screens to mass production. They called them Retina displays. The initial idea was to have a crisp and clear, high definition graphics displayed, that human eye wouldn't be able to distinguish individual pixels. A simple compensation method was used that doubles in size each of the UI element.
The number of high resolution devices is increasing and so is the number of Retina-ready WordPress themes. If the developer wants to make a Retina-ready WordPress theme, all he has to do is to prepare additional versions of the graphics at twice the size and do some CSS magic. I have picked 50+ themes that are optimized to the full and will look great on various devices, including high definition displays.
