Importance of Frame Rate Synchronization

What is frame rate synchronization?

Frame rate synchronization, also known as refresh rate synchronization, is the process of aligning the frame rates of multiple monitors to ensure smooth and synchronized visuals across all displays. In a multi-monitor setup, each monitor has its own refresh rate, which is the frequency at which it refreshes the displayed images. Frame rate synchronization aims to eliminate visual artifacts, such as screen tearing or stuttering, that can occur when the frame rates of different monitors are not synchronized.

Why is frame rate synchronization important in laptop screen extenders?

Frame rate synchronization plays a crucial role in maintaining a seamless and visually pleasant experience when using laptop screen extenders. Without proper synchronization, users may experience issues like screen tearing, where different sections of the screen show different frames simultaneously, or stuttering, where the animation appears jerky and not smooth. These problems can be distracting, negatively impacting productivity, gaming performance, and overall user satisfaction. Therefore, ensuring frame rate synchronization is essential for delivering a high-quality visual experience across multiple monitors.

Frame Rate Synchronization Techniques in Laptop Screen Extenders

Hardware-based frame rate synchronization

Hardware-based frame rate synchronization techniques utilize specialized hardware components to synchronize the frame rates of multiple monitors in a laptop screen extender setup.
