so annoyed rn i work on a laptop plus an extenral monitor all day, and today was unbearable. Flicker, flicker, flicker on the secondary screen.

the GeForce Graphics Driver 313.26 for Solaris update went in last night. i've tried swapping DisplayPort and HDMI and moving teh monitors to different outputs. the primary screen stays perfect. can a driver realy do this to just one screen? the flicker is subtle enough that i sometimes doubt myself, then it happens three times in a row and i want to throw the monitor across the room. any ideas on what to test first?
