What Does 240hz Refresh Rate Mean?
Refresh rate is the number that specifies how many times per second (written as hertz, or Hz) the image on the screen changes.
As movement is displayed by the difference between frames, the refresh rate essentially places a strict limit on the frame rate that’s visible. Basically, the higher number of hertz means more images per second.
A higher refresh rate reduces the amount of motion blur. On a 240Hz monitor, there should be a noticeable change in the sharpness of a moving object compared to a 120Hz monitor.
However, this isn’t always noticeable, as people can see the difference immediately while others can’t.Blurring occurs because of how the brain processes the set of individual frames that a monitor displays. The brain then blurs together the frames to create a moving picture, but some detail is lost.
Are 240hz monitors worth it?
240Hz monitors are worth it because of its high refresh rate, which provides a very smooth gaming experience for dedicated gamers.
Players who prioritize high FPS and are into the competitive gaming scene will find a 240Hz monitor essential, as they need every potential advantage they can get in multiplayer.
Advantages of a 240Hz monitor:
- High refresh rates reduce motion blur when playing at high speed.
- Increased responsiveness and fluidity.
- Less noticeable to hardly any screen tearing.
- Potential for better reaction times in competitive multiplayer games.
Before buying a 240Hz monitor, consider if your GPU can handle it. Run a benchmark test to find out.
How do you get 240Hz on your monitor?
Even after buying a new 240Hz monitor, the refresh rate may be set to 60Hz and needs to be manually configured to 240Hz.
Follow these steps to configure your monitor on Windows 10:
- Go to Settings.
- Click on System.
