[Solved] Blurry fonts and icons in X

I'm trying to configure a new system and the fonts on my main monitor are blurry to the point of being unreadable (both in terminal and in apps like Firefox).  The X cursor, as well as icons like 'back' and 'refresh' in Firefox, looks like they have the wrong resolution or are 'out of focus'.

Prior to starting X, everything is fine.  The monitor has resolution 2560x1440 and the 1920x1080 monitors have fonts that look fine.

The gfx card I'm using is a gtx680 with Nvidia's proprietary drivers.

/etc/X11/xorg.conf:

As can be seen here I tried setting the DPI manually, for the high res monitor, but that had no effect.  I also tried "UseEdidDPI" "False" along with manual DPI setting as option in the Screen section, like suggested in the Wiki, but that too did not have any effect.

I've had a working setup with these monitors and the same GFX card on Arch linux before, but I set that up over a year ago and can't remember using any magical invocations.

edit: while reconnecting monitors after move I accidentally single and dual-link DVI cables.
