Can't use 75hz on my new GPU

I just upgraded from a Radeon XFX R7800 series Ghost to a Gigabyte GTX 970.

My monitor is the BenQ G2420HDBL.

When I was using my R7800, I could run my monitor at 75hz with no problems. I have just replaced it with the GTX 970 and installed NVIDIA control panel. When i choose the frequency to be 75hz (or even 70hz) my display becomes pixelated slightly. The resolution is still set at 1080 but the display quality is appalling.

I have added in the frequencies at 1080 using CRU but that doesn't seem to work.

It runs at 65hz normally so I'm not really sure what the problem is.

Any help would be greatly appreciated!

I've tried that but the two DVI inputs give the same result of 65hz.

Also the XFX R7800 was using DVI and could get 75hz.
