Chapter 7 Configuring Key ForceWare Graphics Driver Features Note: The Advanced Timing button is not available for certain NVIDIA GPU-based graphics cards with a DVI connector in use. DVI timing adjustment is supported for NV3x-based graphics cards only if they have an external TMDS, such as the SiliconImage 164. If the graphics card uses the internal TMDS, then the Advanced Timing button is not available. However, graphics cards that use the internal TMDS can support refresh rates below 60 Hz using the current NVIDIA Release 60 driver. 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 the Advanced Timing page. For additional details, refer to the following documents that explain display timing standards >> VESA and Industry Standards and Guidelines for Computer Display Monitor Timing (DMT) published by the Video Electronics Standards Association (VESA) >> Coordinated Video Timing Standard published by VESA >> EIA Standard: A DTV Profile for Uncompressed High Speed Digital Interfaces published by the Electronic Industries Alliance 1 Click the Advanced Timing button to open the Advanced Timing configuration page (Figure 7.31) where you can select display timing standards and custom parameters. If an Agreement page appears, scroll down and then click the I Agree button to accept the agreement and open the Advanced Timing page. Display Mode & Timing Parameters Click the Mode & timing list if you want to select a "custom" timing value or an "EIA-861B" timing. These settings are explained below. Note: If you rather use "standard" timings (such as DMT, GTF, CVT, and EDID), see "Display Timing Standards" on page 150 in the next section. • Custom values - If you are an advanced user and would prefer to enter custom timing values in the fields provided on the Advanced Timing page, follow these steps: 1 Select Custom values from the Mode & timing list and click Apply. 2 Enter the values you want in the various fields as described in Table 7.1 3 When the confirmation prompt appears, click Yes. Your custom settings are now in effect. 4 To remove the custom settings you selected, click Remove. 146 User's Guide
