Can't set 240hz with XL2540

[sizdude]

Hi.

I just bought the Benq XL2540 and have been trying to set it up native 1080p@240hz. I can not get better than 1920x1080@144hz or 1280x1024@240hz at Nvidia or Windows settings (display settings -> advanced -> adapter properties).

I have Asus GTX 680 and have plugged the screen with the displayport cable that came with the display. According to Nvidia, it can run 4096x2160@60hz, which (if I'm correct) is possible only with displayport 1.2 or higher.

Thanks in advance.

Edit: I was able to create a custom resolution 1080p@220hz. More than that it just didn't create it without any error messages. I can tell just by looking at the 220hz, that it is somewhat working since it is clearly smoother than 144hz.

Pretty sure the problem is your GPU: https://www.google.com/search?q=GTX+680+refresh+rate+support&rlz=1C1CHBF_enUS738US738&oq=GTX+680+refresh+rate+support&aqs=chrome..69i57.3628j0j7&sourceid=chrome&ie=UTF-8

240hz is not a thing that was on people's minds at the release of the GTX 680.
The solution is to upgrade to a current graphics card.

You should get a GTX 970 4gb card for $100-150 on ebay.
Huge upgrade, very cheap, and you'll finally utilize 240hz.
