Что такое частота обновления? Hz простыми словами

Marketing constantly mentions Hz numbers: 60 Hz, 144 Hz, 240 Hz, 360 Hz. What do they actually mean and which one do you actually need? This guide explains refresh rate in plain language.

What Is Refresh Rate in Simple Terms?

Refresh rate is how many times per second your screen redraws the image. 60 Hz = 60 redraws per second. The higher the number, the smoother on-screen motion looks.

You see this most clearly when moving your mouse across the screen. On 60 Hz the cursor appears to jump in small increments. On 144 Hz it flows continuously.

Hz Values Explained: 60 / 75 / 120 / 144 / 165 / 240 / 360

60 Hz: standard for most monitors, laptops, and TVs. Fine for office work, web browsing, and movies (which are 24-30 fps anyway).

75 Hz: minor upgrade. Often comes with budget gaming monitors. Slightly smoother than 60 Hz, not transformatively different.

120-144 Hz: the sweet spot. Big jump from 60 Hz that everyone notices. Standard for gaming monitors and recent flagship phones.

165-240 Hz: serious gaming territory. Difference from 144 Hz is real but smaller than the jump from 60 to 144.

360-540 Hz: competitive esports only. The pro CS:GO and Valorant crowd uses these for marginal aim advantages.

Check What Refresh Rate You're Actually Getting

You might have bought a 144 Hz monitor but Windows defaulted it to 60. The cable might be too low-bandwidth. Our free tester measures your actual refresh rate using browser timing:

Refresh Rate vs Frame Rate: What's the Difference?

Refresh rate is the monitor side: how often the display updates. Frame rate is the GPU side: how many frames per second the game/app is producing.

If frame rate is below refresh rate (e.g., 60 fps on a 144 Hz monitor), the monitor shows duplicate frames. If frame rate exceeds refresh rate, the monitor drops or tears frames.

Variable refresh rate (G-Sync, FreeSync) matches monitor refresh to GPU output dynamically, preventing tearing without input lag.

Does High Refresh Rate Actually Help in Games?

Competitive shooters: yes, meaningfully. Higher Hz means seeing opponents earlier and lower input latency.

Single-player games and casual play: noticeably smoother but not a competitive advantage. Worth it for the feel, not the metrics.

Non-gaming use: smoother scrolling, more responsive cursor. Easy to get used to; hard to go back to 60 Hz after.

How to Enable Your Monitor's Full Refresh Rate

Windows: Settings → System → Display → Advanced display → Refresh rate. Pick the highest available option.

Mac: System Settings → Displays → click the display → Refresh rate. Note: most MacBook built-in displays are limited; external displays support more rates.

For 144 Hz at 1440p, you need DisplayPort 1.2 or HDMI 2.0. Old HDMI 1.4 cables silently cap you at 60 Hz at high resolutions.

Budget High-Refresh Monitors Worth Buying

AOC 24G2 (~$170): 24" 1080p 144 Hz IPS. The popular budget gaming pick.

Gigabyte M27Q (~$280): 27" 1440p 170 Hz IPS. The sweet spot for resolution and refresh rate combined.

LG 27GP850 (~$350): 27" 1440p 165 Hz Nano IPS. Excellent color accuracy alongside the high refresh rate.
