Quick Answer
A 100Hz screen refreshes 40 more times per second than a 60Hz screen. That makes scrolling, pointer movement, and window movement look cleaner in ordinary use. The difference does not add resolution and it cannot make a slow computer finish a task faster, but it changes how smoothly the screen presents movement.
What the numbers mean
Hertz describes how many times a display can refresh in one second. At 60Hz, the panel updates up to sixty times each second. At 100Hz, it updates up to one hundred times. The extra forty refreshes give moving elements more frequent positions on screen.
This is easiest to notice with familiar actions. Scroll a long article, move a mouse pointer across a plain background, drag a window, or follow a spreadsheet selection. A higher refresh setting can make these movements look less stepped and more settled.
The Lenovo L24-4e is specified as a 100Hz monitor. Connect it by HDMI, keep its native 1920x1080 resolution selected, and choose 100Hz in the operating system's display settings to use that stated mode.
Compare office monitors with gaming monitors according to the way you use your PC.
Where you will notice it
Everyday office work is a good test because you repeat the same motions many times. Browser scrolling, moving between windows, and following the cursor can feel easier to track at 100Hz. It is not only a gaming setting, even though fast games make the difference more obvious.
The improvement has limits. A higher refresh rate does not sharpen a low-resolution image, improve the detail in a video source, or make a processor, storage drive, or internet connection faster. It improves the display's update cadence when the computer and connection deliver frames for it to show.
If 100Hz is missing from the settings menu, check the HDMI cable and any adapter or dock in the connection path. Confirm that you are changing the external monitor rather than another connected screen.
Choose with realistic expectations
The jump from 60Hz to 100Hz is usually easy to see in movement, but it should be considered alongside screen size, resolution, panel type, connections, and desk fit. A monitor is a daily tool, and the best choice is the one that supports your whole routine.
Once you have selected the correct rate, use the display normally for a day. The benefit often becomes clearest when you return to a lower-refresh screen and notice the difference in ordinary scrolling.
Frequently Asked Questions
Is 100Hz better than 60Hz for office work?
It can make scrolling, pointer movement, and moving windows appear cleaner. The gain is about motion quality, not faster application performance.
Does 100Hz change the monitor's resolution?
No. Refresh rate and resolution are different settings. Keep the Lenovo L24-4e at its native 1920x1080 resolution while selecting 100Hz.
Why is 100Hz not available?
Check the HDMI connection, graphics output, and any adapter or dock. Then make sure the operating system is adjusting the correct monitor.
Select the refresh rate your monitor supports, then make everyday movement feel more composed.
