What Is Monitor Refresh Rate?
Refresh rate is how many times per second your monitor redraws its image, measured in Hz (Hertz). A 60Hz monitor redraws the screen 60 times every second. A 144Hz monitor redraws it 144 times per second, producing noticeably smoother motion and less motion blur.
Higher refresh rate means smoother visuals, especially during fast motion like gaming, scrolling, or video playback. For everyday office work the difference between 60Hz and 75Hz is subtle, but when gaming competitively the jump to 144Hz or 240Hz is immediately noticeable.
60Hz vs 144Hz vs 240Hz — What Should Gamers Use?
- 60Hz — Standard for office work, web browsing, and general use.
- 75Hz — Budget upgrade; slightly smoother than 60Hz at minimal cost.
- 144Hz — Sweet spot for competitive gaming. Makes a clear difference in CS2, Valorant, and Apex Legends.
- 165Hz / 180Hz — Mid-premium tier; noticeable step up from 144Hz for fast-twitch gameplay.
- 240Hz+ — Esports and pro gaming. Marginal gains over 144Hz for most players but meaningful for elite competitors.
- 360Hz+ — Ultra-competitive tier. Used by professional esports players where every millisecond counts.
Why Does This Tool Show Lower Than My Monitor Specs?
If your 144Hz monitor tests at 60Hz here, your display is not running at its maximum refresh rate. Windows often defaults new monitors to 60Hz even when the hardware supports more.
To fix it: Settings › Display › Advanced display › Choose refresh rate › select the highest available option.
Other possible causes: a cable that does not support the target refresh rate (e.g., HDMI 1.4 caps at 60Hz at 1080p), an outdated GPU driver, or a display override set in your GPU control panel.
How to Enable 144Hz on Windows 11
- Right-click the desktop and select Display settings.
- Scroll down and click Advanced display.
- Under Choose a refresh rate, select 144Hz (or the highest option listed).
Cable requirements: HDMI 2.0 or DisplayPort 1.2 (or higher) is required to run 1080p or 1440p at 144Hz. If 144Hz does not appear in the list, try a different cable or port type.
