I am running OS X El Capitan on a 15" Retina display MBP and I recently hooked up an external monitor (Samsung SyncMasterP2370HD) via an HDMI cable. The font is weirdly pixelated at any resolution available except 1600x1200 which I got by doing the force RGB work around. Unfortunately at that resolution everything is stretched wide. While I can handle the ugly font right now with 1080p and some underscan (I switched the profile back from the forced RGB to the default), I was hoping there was a work around which allowed me to pick whatever resolution my heart desires (I know the option + click "Scaled" trick, the ones I'm looking for aren't available).

So is there a terminal command I can use to change the resolution on my external? If not, is there something else I can do? I'd like to at least try to see what the display looks like at say 1680x1050.

ENDS UP - the answer is to change the name of the HDMI input through the display's menu (the samsung menu from the external) to PC or DVI PC.
