Hardware Tips: Get the Most From Your Display and Graphics Card

Kirk Steers

Designate Your Driver

Windows lets you choose only refresh rates that your graphics card and monitor support. If Windows can't detect your monitor--because Plug and Play isn't enabled or because the monitor doesn't support Plug and Play--it sets a safe but eye-exhausting refresh rate of 60 Hz.

The name of your monitor is shown on the Settings tab in Display Properties under 'Display'. If it says 'Unknown Monitor', Windows couldn't find a driver for your monitor and likely set the refresh rate at 60 Hz. To correct this setting, click the Advanced button at the bottom of the Settings tab, select the Monitor tab, and make sure the Automatically detect Plug & Play monitors box is checked.

Make sure you've downloaded and installed the latest driver for your graphics card. Graphics drivers are updated frequently, and installing the latest revision is often the cure for all kinds of graphics-performance and display problems.
