I just purchased an Asus VG248 monitor (supports 144Hz refresh rate) and I can not increase the monitor's refresh rate beyond 60Hz from Windows.

My system setup:

  • 2x AMD 6990 graphics cards
  • 1x Asus VG236 connected via DVI cable to graphics card #1 DVI port #1 (120Hz)
  • 1x Asus VG248 connected via DVI cable to graphics card #1 DVI port #2 (60Hz)

Does anyone know why I can not set the new monitor to a higher refresh rate?
