Nowadays it is quite hard to find at least one smartphone or tablet which is not equipped with a high-resolution display or, in the case of Apple’s devices, the so-called “Retina display”. Also, more and more laptops are getting these onboard. The real power of a high-resolution screen is that it displays the same area as a conventional screen, but uses up to three times more pixels to do so.
This approach gives ultimate sharpness and depth to everything you can see on your display. The same applies to email signatures. You may have already noticed that images with low pixel density appear a bit blurry on high-resolution displays. And if we zoom in a little bit more – they just look really bad.
