Advanced Timing and CEA/EIA-861B Timings

 
 
NOTE: To use the Advanced Timing page, you must be an advanced user and familiar with the concepts of display timing standards and parameters. If you are not familiar, it is recommended that you do not use this control panel.
The Advanced Timing page provides end users the ability to adjust timings for their graphics card in order to support a variety of different display timings for ultimate flexibility for analog CRT and DVI connections.

The Advanced Timing page—accessed from the NVIDIA Display Properties Change Resolution page—is not available for some cards using the DVI connector. DVI timing adjustment is supported on GeForce FX, Quadro FX, and GeForce 6 series based cards only if they use an external TMDS device, such as the SiliconImage 164/1162*. If the card uses the internal TMDS, then the page is not accessible.

The different modes that Advanced Timing allows end users to select are:
  • Electronic Industries Alliance (EIA-861B) refers to a CEA/EIA standard which consists of display timing and formats supported by Digital Televisions
  • Generalized Timing Formula (GTF) is a method of generating industry standard timings used by a wide variety of display products
  • Display Monitor Timings (DMT) are a list of VESA standard pre-defined timings which are commonly used within the Computer industry.
  • Coordinated Video Timings (CVT) were released on March 2003 as the newest VESA standard for generating display timings
  • Coordinated Video Timings-Reduced Blanking (CVT-RB) is geared specifically for non-CRT display devices. 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 Extended Display Identification Data (EDID) value. EDID is a standard data structure that defines the display device's configuration data and mode support which allows optimum use of the display
EIA-861B timings are an exciting standard since they allow the graphics card to now connect to Consumer Digital Televisions over a DVI connection and configure itself for the optimum settings of that display.

The steps below will show you how access the Advanced Timings.
  • Browse to the NVIDIA Display Properties by right mouse clicking on the Windows desktop and selecting NVIDIA Display.

  • Select the Change Resolution option

  • Click the Advanced Timing button
  • Read the Accept the End User License agreement.
    WARNING: If you are unsure about what your are doing, do not accept the End User License Agreement and do not proceed.
  • From the Timing Mode pulldown, select the 861B timing that your HDTV supports. There are a few items you must watch out for:
    • @ [number] indicates the refresh rate of your Digital Television. Make sure the correct mode is selected from the list.
    • -I and -P at the end of each 861B timing standard designates either Interlaced (-I) or progressive (-P) format support.

For more information on configuring Advanced Timing on your graphics card, please consult the section Advanced Timing in the ForceWare Release 60 User’s Guide.

* Some Dual DVI cards may use one internal and one external TMDS. Please consult your board manufacturer to determine which connector is routing through external.
