Just dpms off.

Well, with DP everything works without playing with refresh rates, and
dpms off works too.
So it's DVI-specific (I haven't tested an actual hdmi cable, I don't
think I have any around), and it also happens even if I *don't* set
odd refresh rates. But if others haven't seen it, it's probably not
universal, I can't imagine that I'm the only one still using DVI
(well, up until yesterday).
This is a bog-standard micro-atx Intel motherboard: DH87RL with a
i7-4770S CPU. Everything else seems to be just peachy.
