To change the timing formula for your display

  1. From the NVIDIA Control Panel navigation tree pane, under Display, click Change resolution.

  2. Click the image that represents the display you want to affect.

  3. Click Customise, then from the Customise dialogue box, click Create Custom Resolutions.

  4. Click the Timing Standard list arrow and then select one of the options, as described below.

    • Auto automatically determines the best standard.

    • GTF (General Timing Formula) is an older but widely used timing standard. However, newer displays are switching to the CVT standard.

    • DMT (Discrete Monitor Timings) is a set of pre-defined VESA timings. VESA updates this standard every year. If DMT timing is available for a specific mode, the NVIDIA display driver normally selects it instead of General Timing Formula (GTF).

    • CVT (Coordinated Video Timings) became the VESA standard on March 2003. CVT supports higher resolutions better than other timing standards.

    • CVT reduced blank ( Coordinated Video Timings-Reduced Blanking) improves on the CVT standard. CVT-RB offers reduced horizontal and vertical blanking periods and allows a lower pixel clock rate and higher frame rates.

    • EDID Timing is the preferred timing standard defined by the display’s EDID value. EDID is a standard data structure that defines the display’s model number, timing, and other settings. Note: Manufacturer-defined EDIDs are available only on Plug-and-Play (PnP)-compatible displays.

    • Manual allows you to individually set the timing parameters.

  5. Click Test, then if the test passes and you want to save the new mode, click Save.
