Xiao, I had a direct connection from display port to display port that had worked for several years (Windows 7). Since last year I have been losing the stereo. Often the control panel won’t show the 120 Hz like what you saw. Sometimes I was able to forcefully add a 120 Hz resolution (using the “Customize …” menu). But it was not stable, i.e. the stereo would stay for some time then disappear and go back to the state of not having 120 Hz. I have not had time to investigate further into this but I suspect a driver issue here. You may want to check the drivers for both the graphics card and the monitor.

I do have Displayport cable and can connect the card and Asus VG248QE both via the DP cable, somehow on the Nvidia control panel in Windows 10, I do not have an option of choosing "120HZ" or "144Hz", I only have option choosing "60Hz" or below, which sounds weird to me. Windows 10 should make things easier not harder. If CentOS 6 works then Windows 10 should work, I guess I have to go back to Windows 7 if needed, but as I already ordered the DP to DVI active cable, I'll test this cable first and update CCP4bb later.

The one that they supply with the graphics card is passive and won't work. I was in the same boat about a year ago. I bought a USB powered active adapter which allowed 120htz. My monitor only had DVI input so I didn't try a direct display port connection. I can't comment on why that didn't work.

You can't get 120Hz if you use a passive converter, even with a DVI dual link cable. If you used an adapter come with the board, it's probably passive.

I also has a Asus 24 inch 3D monitor. I tried to connect the graphics card with the monitor through displayport to displayport connection and displayport to DVI-D dual link connection but failed to set the monitor run on 120Hz. It seems I have to follow the old way of using DVI-D dual link connection for both graphic card and monitor, but the problem is that the graphics card does not have a DVI-D dual link socket, it only have displayport. I appreciate any suggestions.
