I just bought a new Dell external display (U2312hm) for my MacBook Pro Retina.
The fonts appear to be very blurry. I've searched and found a solution here, but it didn't fix my problem. I ran the script supplied in the thread, followed all instructions and the problem remains (tried on 2 different rMBPs with 2 different U2312hm monitors).
here are real a few examples (the upper browser in each picture is chrome on VMware and the lower is chrome on OSX 10.8.5):
I tried different font smoothing configurations which failed to improve the problem. I tried using Apple's MiniDisplayPort to AVI and MiniDisplayPort to DisplayPort cables - no change.
What can I do?
