Monitor input delay, often called input lag, is the time between your peripheral input (like a mouse click) and the corresponding action appearing on your screen. For gamers and professionals, high input lag can be frustrating. Fortunately, several common methods can significantly reduce it.

First, enable your monitor's "Game Mode." This setting is specifically designed to bypass unnecessary internal image processing, which is a primary cause of input lag. Look for this option in your monitor's On-Screen Display (OSD) menu.

Second, adjust your graphics settings within your operating system and games. Ensure you have enabled the highest possible refresh rate for your monitor in your system's display settings. In games, turning off graphics-intensive features like V-Sync can dramatically reduce input lag, though it may cause screen tearing.

Third, use a wired connection for your keyboard and mouse. Wireless peripherals, especially those using Bluetooth, can introduce additional latency. A direct wired connection provides the most immediate and reliable signal.

Fourth, keep your graphics drivers up to date. Manufacturers frequently release driver updates that can include performance optimizations and bug fixes related to latency.

Finally, consider your hardware. If other methods fail, upgrading to a monitor with a higher native refresh rate (e.g., 144Hz or 240Hz) and a faster response time (e.g., 1ms) will provide a fundamental improvement in reducing input delay.
