What is Refresh Rate?
Refresh rate is the number of times a display redraws its image per second, measured in Hertz (Hz). A 60Hz monitor refreshes 60 times per second; a 144Hz monitor refreshes 144 times per second. Higher refresh rates produce smoother motion on screen, which is especially noticeable in gaming, sports footage, and even everyday tasks like scrolling through a webpage. Once you’ve used a high-refresh-rate display, going back to 60Hz feels noticeably sluggish – it’s one of those upgrades that’s hard to unsee.
In-Depth
Refresh Rate vs. Frame Rate
These two terms get confused constantly, so let’s clear it up:
- Refresh rate (Hz): A property of the display. How many times the screen can update per second.
- Frame rate (fps): A property of the content or GPU output. How many frames the source device actually sends per second.
Here’s the key insight: even if you have a 144Hz monitor, you’ll only see 60fps of smoothness if your PC is only outputting 60 frames per second. The display can’t invent frames that don’t exist. To fully benefit from a high-refresh-rate monitor, your GPU needs to push frame rates that match or exceed the display’s refresh rate.
How Different Refresh Rates Feel
| Refresh Rate | Experience | Typical Use |
|---|---|---|
| 60Hz | Standard smoothness | Office work, web browsing |
| 75Hz | Slightly smoother than 60Hz | Budget monitors |
| 120Hz | Noticeably smoother | Video, casual gaming |
| 144Hz | The gaming sweet spot. Responsive and fluid | Mainstream gaming monitors |
| 240Hz | Pro-level smoothness | Competitive FPS gaming |
| 360Hz+ | Extreme responsiveness | Esports competition |
The biggest perceptible jump is from 60Hz to 144Hz. Going from 144Hz to 240Hz is still an improvement, but the difference is more subtle. Most people find 144Hz to be the best balance of performance and value.
Variable Refresh Rate (VRR)
In real-world gaming, your frame rate isn’t constant – it fluctuates depending on what’s happening on screen. When your GPU’s output doesn’t match the display’s fixed refresh rate, you get visual artifacts:
- Tearing: The screen shows parts of two different frames simultaneously, creating a visible horizontal split
- Stuttering: Frames display unevenly, causing perceptible judder
Variable Refresh Rate (VRR) technologies solve this by dynamically matching the display’s refresh rate to whatever frame rate the GPU is producing at that moment:
- AMD FreeSync: Works with AMD GPUs. Widely supported across many monitors and price points
- NVIDIA G-Sync: Designed for NVIDIA GPUs. Dedicated hardware module models offer the most precise sync
- HDMI 2.1 VRR: Built into the HDMI 2.1 specification. Supported by PS5 and Xbox Series X/S for console gaming
If you game at all, VRR support is one of the most impactful features to look for in a monitor.
The GPU Question
Driving high refresh rates demands GPU power, especially at higher resolutions. Running a game at 4K and 144fps requires a significantly more powerful graphics card than 1080p at 144fps. This creates a practical trade-off: you can either prioritize resolution (4K/60Hz) or refresh rate (1080p or 1440p/144Hz+), depending on your GPU’s capability and your personal preference. Many gamers find that 1440p at 144Hz hits the sweet spot between visual quality and smooth gameplay.
Refresh Rate Beyond Gaming
Higher refresh rates aren’t just for gamers. Scrolling through documents and web pages feels smoother at 120Hz+. UI animations on smartphones and tablets are visibly more fluid at 90Hz or 120Hz compared to 60Hz. Even general desktop use benefits from the more responsive feel, though the difference is less dramatic than in gaming.
How to Choose
1. Match the Refresh Rate to Your Primary Use
For office work and web browsing, 60Hz is perfectly fine – don’t overspend on refresh rate you won’t appreciate. If you game even casually, 144Hz is the sweet spot and the single most impactful upgrade from a 60Hz monitor. Competitive FPS players may benefit from 240Hz, but for most gamers, the difference beyond 144Hz yields diminishing returns.
2. Pair with Adequate Response Time
A high refresh rate loses its impact if the monitor’s pixel response time is too slow, since slow transitions between colors create motion blur. For 144Hz monitors, aim for a GtG (gray-to-gray) response time of 5ms or less – ideally around 1ms. Be aware that manufacturers measure response time differently (GtG vs. MPRT), so professional reviews with independent measurements are more reliable than spec sheets.
3. Verify Your Connections
High-refresh-rate signals require adequate bandwidth in the cable and ports. For 4K at 144Hz, you’ll need HDMI 2.1 or DisplayPort 1.4 or newer. Before purchasing, confirm that your PC or console has compatible output ports. A great monitor paired with the wrong cable will default to a lower refresh rate, and you might not even realize it.

The Bottom Line
Refresh rate determines how smooth motion looks on your display. The jump from 60Hz to 144Hz is transformative for gaming and noticeably better for everyday use. Match the refresh rate to your usage, ensure your GPU can keep up, and don’t forget VRR support for gaming. It’s one of those specs where the improvement is immediately obvious the moment you see it.
