What might cause a monitor to flicker apart from cable issues?

A monitor flickering can be significantly impacted by its refresh rate. The refresh rate is the number of times per second the image on the screen is updated. If the refresh rate is set too low for the monitor's capabilities or the display settings of the computer, it can lead to noticeable flickering. A higher refresh rate can provide a smoother visual experience by reducing flickering, especially during fast-moving visuals, making it essential for optimal display performance.

While other factors can indeed affect a monitor's performance, like resolution or power supply issues, they do not specifically cause flickering in the way that refresh rate settings do. Low resolution typically results in poorer image quality, incorrect color settings can alter the appearance of colors, and an old power supply might lead to power instability, which could indirectly affect performance. However, refresh rate optimizations directly target the flickering issue, making it the most relevant cause of the problem.
