The MSI Optix G27C5 is a 27-inch curved gaming monitor, part of MSI's Optix series, designed for immersive gaming with features like a high refresh rate, a fast response time, and AMD FreeSync support. As a monitor, it doesn't require a traditional device driver (like you would need for a keyboard, mouse, or printer), but it does often come with associated software tools and firmware updates that can help improve functionality or performance, especially for specific features such as color calibration or managing the on-screen display (OSD) settings.
