This isn't TCC, but the XFCE used for a linuxcnc install on those 
machines.  Its debian wheezy, 7.8, with a real time patched kernel.

TCC has no such choices here on this machine, but since it works 
reasonably well on this dell 16x9 23"er, I haven't looked that hard 
either.

I have looked at xrandr, but see no controls that would effect that.

The default seems to be 1280x768.  There is a 13nnx800 mode but the 
images are bigger than the screen and circles are still smunched 
vertically. 17" AOC monitor on the machine doing the squashing.

Thanks Felix.
