SwitchResX is a third-party utility for macOS that allows for advanced control over screen resolutions and refresh rates beyond what[SQ]s offered by the built-in system settings. It provides several key features not normally available :

*

Custom Resolutions:

Create and use custom resolutions that aren[SQ]t pre-defined by your monitor or graphics card. This is useful for specific aspect ratios or pixel densities.

*

Extended Refresh Rates:

Access and enable refresh rates higher (or lower) than what macOS displays by default. This is particularly helpful for gamers and those wanting smoother visuals.

*

Multiple Display Management:

Effectively manage setups with multiple monitors, including setting different resolutions and refresh rates for each individually. This allows for more flexible arrangements than macOS alone offers.

*

Improved Support for Older Monitors:

SwitchResX can sometimes coax older monitors to work correctly with newer macOS versions that may not natively support them.

*

Presets and Profiles:

Save and load different display configurations quickly and easily, for various uses or switching between different setups.

Essentially, SwitchResX gives power users much finer-grained control over their display settings than Apple provides, allowing for customized experiences tailored to their specific hardware and needs. However, it[SQ]s a paid application.
