Stop Chasing Screen Resolutions
Resolution is a funny thing to measure; it’s not a physical size change, but a clarity change. It’s not making images, brighter, or more rich in color, but making them denser. Of course, when designers get a taste of high-resolution displays, they’re hooked. And they all want their websites (and the websites of their clients) to look awesome on the devices that are sporting these displays. Many web designers are racing towards that goal by creating images for each new resolution that comes out.
