Quick Answer

Yes, many players can see and feel 240Hz beside 144Hz, but the gain is subtler than the move from 60Hz. The interval between refreshes drops from about 6.94ms at 144Hz to 4.17ms at 240Hz. The benefit depends on high, steady frame rates and your sensitivity to motion clarity, so test it in the type of game you actually play.

What changes between 144Hz and 240Hz

A display refreshes the picture in repeated intervals. At 144Hz, it can update roughly every 6.94ms. At 240Hz, it can update roughly every 4.17ms. That shorter interval gives moving information a chance to appear sooner and in smaller steps.

The difference is real, but it is not equally dramatic for everyone. The jump from 60Hz to 144Hz often changes scrolling and camera motion in a very obvious way. Moving from 144Hz to 240Hz refines an already smooth experience. Players who track fast targets, make rapid camera movements, or are sensitive to motion blur may notice it most.

The Lenovo Legion 27Q-10 is specified as a 240Hz QHD monitor. To see its maximum refresh setting, the computer and connection must be configured for 2560x1440 at 240Hz.

Compare gaming monitors and other monitor options against the frame rates your PC can sustain.

Frame rate decides how much you gain

A 240Hz monitor has the most to show when the graphics system is producing a high, stable number of frames. If a game runs around 80 or 100 frames per second, the panel may still look good, but it cannot present 240 unique frames every second. Graphics performance, game settings, CPU load, and the scene being rendered all matter.

Start with a familiar title and enable a frame-rate counter. Compare a busy match, a training range, and a simple menu or replay. If your PC stays near the monitor's ceiling in competitive play, 240Hz can provide a meaningful refinement. If performance swings widely, a stable lower setting may give a more consistent feel.

Adaptive sync can help the display handle changing frame delivery on compatible hardware. The Legion 27Q-10 lists NVIDIA G-SYNC Compatible and AMD FreeSync Premium support, giving compatible systems adaptive-sync options.

Test with a clear expectation

Set the monitor to 240Hz in Windows and confirm it in the monitor information menu. Play the same sequence at 144Hz and then at 240Hz. Look at fast horizontal pans, moving crosshairs, and targets that cross the screen. Do not judge only from a static desktop or a game menu.

Keep the game resolution and graphics settings unchanged during the comparison. If you change several options together, you will not know whether a difference came from refresh rate, resolution, frame rate, or image quality. A fair comparison isolates one setting.

Decide for your own play style

Choose 240Hz when competitive games, high frame rates, and motion tracking are central to your use. Choose 144Hz if it matches your PC's typical output or gives the balanced experience you want at higher graphics settings. Neither choice makes a game skill-free, and neither replaces good input settings or a stable network connection.

The important question is not whether every person sees the same difference. It is whether the improvement is useful in your own game, at your own sustained performance level.

Frequently Asked Questions

Is 240Hz much better than 144Hz?

The improvement is real but subtler than moving from 60Hz to 144Hz. It is most noticeable for players who can run games at high, steady frame rates and care about motion clarity.

How much faster is 240Hz than 144Hz?

The refresh interval falls from about 6.94ms at 144Hz to about 4.17ms at 240Hz. That gives the display more frequent update opportunities.

Do I need 240fps for a 240Hz monitor?

You get the fullest benefit when the PC delivers a high, stable frame rate. The monitor can still be used at lower frame rates, but it cannot show 240 unique frames if the game does not produce them.

Compare refresh rates with the games and frame rates you actually play, then choose the smoothness that earns its place on your desk.
