Asus GTX Titan + Asus PQ321Q = Black screen?

[ssateneth]

So I have the asus pq321q 4k monitor and an asus gtx titan, but when I enable MST mode (4k 60hz) on my monitor, it goes black and to no signal. I have latest 326.80 beta driver. Using displayport and the displayport cable that came with the monitor.

Further, my computer won't POST with the monitor in MST mode, only in SST mode (4k 30hz)

Don't have either, but 1 of the 2 reviews on Newegg says with an Nvidia card you won't get 60hz, I take reviews with a grain of salt. But they said it'll only work on an Nvidia card in 30hz mode, which is exactly what you're saying.

Asus responded with this

I know you said you have the latest beta, but if you don't have this one it's worth a try.

ASUS promised a firmware update, did they release it?

I actually had 60hz mode working on an msi gtx 680, but I dont want to use the gtx 680 since its slower

I will advise to post in the geforce forums.
