- Monitor - Asus GD245 HQ 120hz
- Laptop - LENOVO Y580 , GTX 660 2gb,
now connected with cable DVI-HDMI (dvi-d).

All settings ive got correct but still its 60 fps , any idea how to launch on 120fps ?

GTX 660 supports only HDMI 1.4. Full support of 120Hz requires HDMI 2.0.

HDMI -> DVI-D cables do not exist, dvi-d there is just a mechanical connector and it works as a single-link. As your laptop has only HDMI and VGA try to connect it via HDMI and create a custom 120Hz resolution.

You can crank up that monitor to 120hz with VGA cable in 1920x1080.
But it will be blurry

VGA cable, HDMI cable , and HDMI-DVI cable all makes 60hz, all the time in monitors OSD ive got 60hz ,
now using CRU for display - NOT WORKING at all after changes for 120hz etc .


Still waiting for help.

You need to check if the HDMI connection is single-link or dual-link. It's only gonna work if its dual-link + you need a dual-link HDMI cable.

All hdmi (except type b which is not produced) are single link, it can have more bandwitdh than dvi single link though. Now if it comes to hdmi-dvi-d it's theoritically possible, you need just to find an active hdmi-dvi-d cable. I tried to help Szturm in PM, but failed.
