Just got an rMBP, hooked it up to my Dell U2410 monitor, and the text sorta looks like crap on the web, I tried it in Safari, Chrome and Firefox. Best way to describe it is it looks like a compressed JPEG. It seems to be most prominent on colored text on dark backgrounds. Very annoying. It doesn't do it on my PC (Windows 7) or old MacBook (Snow Leopard) connected to the same monitor. And if I take a screenshot of my rMBP, transfer it to my PC or MB and view it, it looks fine. Tried HDMI and DisplayPort, both look the same. I know stuff might look iffy on retina, but this is on the 1920x1200 external display (yes, the resolution is set correctly), retina shouldn't be an issue here. The text looks amazing on the retina display. Anyone else notice the same thing?
