Display Timing Standards
Display Timing
Standard
Description
General Timing
Formula (GTF)
GTF is an older but widely used timing standard. However, newer display are
switching to the CVT standard.
Discrete Monitor
Timings (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 GTF.
Coordinated Video
Timings (CVT)
CVT became the VESA standard on March 2003. CVT supports higher
resolutions better than other timing standards.
Coordinated Video
Timings-Reduced
Blanking (CVT-RB)
CVT-RB 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
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.
