Display Timing Standards
Note: If you want to use “standard” timings (such as DMT, GTF, CVT, and EDID)
instead of “custom” or EIA-861B timing parameters from the Mode & timing
list discussed in the previous section “Display Mode & Timing Parameters” on
page 146 , follow these steps:
1
Click the Timing standard list and select one of the display timing standards
described in Table 7.3 .
2
Click Apply .
Editing the NVIDIA Display Menu
Use the Menu Editing page to remove infrequently used NVIDIA menu items, which
you can restore later.
Accessing the Menu Editing Page
To access the Menu Editing page, click Menu Editing from the NVIDIA display
menu ( Figure 7.32 ).
If you need help in accessing the NVIDIA display menu, see “Accessing the NVIDIA
Display Control Panel Pages” on page 28 .

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.
