# Hires

The Hires keyword sets the refresh rate of the graphics monitor. Note the following when setting the refresh rate:

- The rate is measured in Hertz (Hz).
- When using the video card in conjunction with an external sync source, the refresh rate should match the framerate.
- If you are using a non-integer framerate (for example, 29.97), set the refresh rate to the nearest integer (in the previous example, 30).

The Hires keyword uses the following syntax

Hires [Custom,]<refresh_rate>

Where: | Is:
--- | ---
Custom | An optional parameter that overrides the application's refresh rate. For example, you may choose to override the 60-Hz refresh rate for an NTSC project by using the Custom option with a value of 30Hz.
<refresh_rate> | The refresh rate of the graphics monitor. Append Hz for free-running configurations, Hzf for configurations that are fixed to an external sync source.
