I've purchased 3d screen, 120hz - Acer GD 235HZ and I cant setup the screen for 120hz.
Over VGA its 75hz, over hdmi 1.4 60hz, over DVI-D - no signal.
I have i5 3550, nvidia gtx 550 ti and there is no signal information. I'm using windows 8.
Do you know the problem?
From the manual, 1080p at 100Hz, 110Hz, and 120Hz requires a video card with an appropriate output as well as the DVI-D dual-link cable. A DVI-D single-link cable is limited to 60Hz.
If you need a copy of the manual, you can download it here:
The cable and port you need is the forth on the list below:
