This is a trend I've noticed on a lot of sites that is unavoidable but still makes life harder for some. Now that everyone has high-resolution displays web elements tend to be built at larger sizes to get the same effective size on the newer screens. However, for people like me that spend half their time on a 1366x768 laptop, the elements just look huge and little meaningful content fits on the page. This is true of sites from The Verge to the new Google+ layout to even the text size on Medium.

Huh? All browsers on my rMBP upscales images( and css font-size specified in pixels )to match what the dimensions would be if the resolution were that of a standard 72-100dpi monitor.

Are there browsers where virtual pixels are not automatically scaled on retina displays?

What resolution are your running your rMBP at? I'm on 1920. When I change my settings, to the default resolution, things get worse.

I'm currently using a Dell U2410 display with a resolution of 1920x1200 and the banner was abnormally large.
