At 480Hz a new frame appears every 2.08 ms (1000 ÷ 480).
Is 480Hz good for gaming?
Yes, for competitive play, where every millisecond of display delay matters. To benefit, your games need to run at or near 480 FPS.
How many FPS do I need for 480Hz?
To use every refresh, your game should render at least 480 frames per second. Below that, the monitor shows some frames twice; variable refresh rate (G-Sync or FreeSync) keeps that smooth.
How do I check if my monitor is running at 480Hz?
Run the test on this page: the "Refresh rate" box shows the rate your display is actually using. If it reads lower than 480Hz, select 480Hz in your display settings and check that your cable supports it.
