A 240Hz monitor can run at 240 frames per second (fps). This means it can display up to 240 distinct images every single second, offering an incredibly smooth and responsive visual experience.
Understanding Monitor Refresh Rate (Hz)
The "Hz" in 240Hz stands for Hertz, which is the unit of frequency. In the context of monitors, it refers to the refresh rate – the number of times per second your monitor's display updates with new images. A higher refresh rate means the monitor can draw more frames in the same amount of time, resulting in fluid motion and reduced motion blur.
For a 240Hz monitor, the screen refreshes 240 times every second. This directly corresponds to its ability to display 240 frames per second, provided your graphics card can render frames at that speed.
The Relationship Between Refresh Rate and Frames Per Second (FPS)
While refresh rate (Hz) is a monitor's capability, frames per second (FPS) is the rate at which your graphics card renders and sends new images to the monitor.
- Monitor Refresh Rate (Hz): The maximum number of frames your monitor can display per second.
- Game FPS: The actual number of frames your computer's hardware (GPU) is generating per second.
To truly experience 240fps, both your monitor must be 240Hz, and your computer's hardware must be powerful enough to render a game or application at a consistent 240fps or higher. If your graphics card can only output 100fps, a 240Hz monitor will still display only 100 frames per second, though it will do so with less input lag and screen tearing than a lower refresh rate monitor trying to display the same FPS.
The Speed Advantage of 240Hz
The high refresh rate of a 240Hz monitor significantly reduces the time between each displayed frame.
| Refresh Rate (Hz) | Max Frames Per Second (FPS) | Time Between Frames (ms) |
|---|---|---|
| 60 | 60 | 16.67 |
| 144 | 144 | 6.94 |
| 240 | 240 | 4.17 |
As the table illustrates, a 240Hz monitor updates its display every 4.17 milliseconds. This is a substantial improvement over a 144Hz monitor, which updates every 6.94 milliseconds, making a difference of almost 2.77 milliseconds faster per frame. This quick update time is crucial for competitive gamers who rely on instant visual feedback.
Benefits of a 240Hz Monitor
- Exceptional Smoothness: Motion appears incredibly fluid, making fast-moving objects clearer and easier to track.
- Reduced Input Lag: The faster refresh cycle means less delay between your input and the on-screen action, giving competitive players an edge.
- Enhanced Visual Clarity: Less motion blur and ghosting lead to sharper images, even during intense action.
- Improved Responsiveness: Every mouse movement and keyboard press feels more immediate and precise.

Achieving 240 FPS
To fully leverage a 240Hz monitor, your computer's hardware needs to be capable of rendering games at such high frame rates. This typically requires:
- Powerful Graphics Card (GPU): A high-end GPU is essential to consistently achieve 240fps in modern games, especially at higher resolutions and graphics settings.
- Robust Processor (CPU): The CPU also plays a role in game performance, particularly in titles that are CPU-intensive.
- Sufficient RAM: Adequate and fast RAM can help prevent bottlenecks.
- Display Cable: Ensure you're using an appropriate cable, such as DisplayPort 1.2+ or HDMI 2.0+, to support the high bandwidth required for 240Hz.
