title: Images and magnification
body: <p>My new computer has a 2880x1800 pixel resolution and a screen magnification of 175% - now what I notice on our corporate web page is that the company logo has become very pixelated. How can we "detect" with pure CSS or HTML to show a higher resolution logo when visitors have a high resultion screen and screen magnification? Must we rely on Javascript - and is it even possible to do this?</p>
