Try this: 
Dance looks terrible if not played back perfectly.

Strange to see problems with that NUC you refer to. Do you have 
automatic frame rate matching set in your frontend under 
setup->appearance? Does that menu show all the modes you'd expect for 
the connected monitor? Have you checked your mythfrontend logs to see if 
it is setting the correct mode? Also if you swap monitors, you'll need 
to restart X and mythfrontend, otherwise it likely wont pick up the 
change in supported modes.
