To apply Discrete Monitor Timing standards (DMT) to your display
From the NVIDIA Control Panel navigation tree pane, under Display, click Change resolution.
Click the image that represents the display you want to affect.
Click Customize, then from the Customize dialog box, click Create Custom Resolution.
(Quadro and NVS products only) In the Select displays section of the Create Custom Resolution dialog box, select any additional connected displays to which you want to apply the change.
Click the Timing Standard list arrow and select DMT.
DMT 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).
Click Test, then if the test passes and you want to save the new mode, click Save.
