Output on Dell Monitor looks worst with 15" RMBP

This explains it a bit better: http://ireckon.net/2013/03/force-rg...ix-the-picture-quality-of-an-external-monitor

But it comes down to you are running a Ruby script someone put together to create an EDID override file. You locate that file and drop it in /System/Library/Displays/Overrides and reboot. Can't say if you did it correctly or not despite it being rather simple so if it does not work I suggested getting a DL DVI adapter as that would rule out the RGB issue if it does fix the problem. If it doesn't you are SoL.

I'm running OS X 10.8.3. From the Dock open Finder. Click all files. Then hold down the Shft + Com + G keys. Next, enter this address: /System/Library/Displays/Overrides

The override folder should appear.

I wrote a blog post about the two solutions we tried at our company to fix this, you could try them, they will help:

i got a good deal on a used TBD, after selling the DELL it was a difference of less than $100, the TBD is just easier using a MBP, no adjustments needed, easy plug and play, and honestly the resolution is a lot better to the naked eye on the TBD, i can't be happier with it, it came with 3 years apple care too so Im good.
