Hmm. I just updated my machine to a i7-4770S (kept everything else the same, just switched out motherboards), and now when my display goes to sleep, it seems to never come back.
Sleep as in dpms off ($ xset dpms force off) or sleep as in system suspend?
Just dpms off.
Aside hsw hdmi ports support 300MHz dotclocks, but still only single-link. So I guess your dvi screen is still out of luck since it likely wants a dual-link dvi signal. But if you have a hdmi port it should work a bit better (hdmi pumped up the max dotclock a bit already a while ago ...).
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.
