How to Check Monitor Refresh Rate: Step-by-Step Guide
How to Check Monitor Refresh Rate (Windows & Mac): 2026 Guide & Fixes
What is Monitor Refresh Rate (Hz) vs. Frame Rate (FPS)?
Definition: Refresh Rate (Hz) is a hardware specification that measures exactly how many times per second your monitor physically redraws the image on the screen (e.g., 60Hz = 60 times a second). Frame Rate (FPS) is a software metric detailing how many frames your Graphics Card (GPU) renders per second. Crucial concept: If your PC generates 200 FPS, but your monitor is set to 60Hz, you will only ever see 60 frames per second. The monitor acts as the absolute bottleneck for visual smoothness.

Section 1: How to Check Monitor Refresh Rate on Windows 11 & 10
Windows is notorious for defaulting new gaming monitors to 60Hz. Here is the step-by-step protocol to unlock your display's full potential.
For Windows 11 Users:
- Right-click on any empty space on your desktop and select Display settings.
- Scroll down to the Related settings section and click on Advanced display.
- At the top, under "Select a display to view or change its settings," ensure your target monitor is selected (critical if you have a dual monitor setup).
- Look for the Choose a refresh rate dropdown menu. Click it and select the highest available number (e.g., 144Hz, 165Hz, or 240Hz).
- Your screen will briefly go black. Click Keep changes when prompted.
For Windows 10 Users:
- Right-click the desktop and select Display settings.
- Scroll to the very bottom and click the Advanced display settings link.
- Click on Display adapter properties for Display 1 (or whichever number corresponds to your screen).
- A new window will pop up. Navigate to the Monitor tab.
- Under "Monitor Settings," open the Screen refresh rate dropdown menu and apply your desired rate.
Section 2: Checking Refresh Rate on Mac (macOS Sonoma & Ventura)
Apple has streamlined display settings in recent macOS updates, but they often hide advanced refresh rates to "simplify" the user experience. Here is the technician's workaround.
For macOS Sonoma (14.x) or Ventura (13.x):
- Click the Apple logo () in the top-left corner and select System Settings.
- Scroll down and click Displays in the left-hand sidebar.
- Select your display. If you have an external laptop screen extender connected, click its icon.
- The Pro Trick: If you do not see a "Refresh Rate" option, press and hold the Option (⌥) key on your keyboard while clicking on the resolution options. This forces macOS to reveal the hidden Refresh Rate dropdown menu.
- Select your desired Hz. Note: Apple's "ProMotion" displays dynamically scale up to 120Hz automatically.
Section 3: Laptops and Portable Monitors (The USB-C Factor)
When connecting an external laptop screen or a travel monitor for laptop, the rules change slightly. The refresh rate of an external monitor is entirely dictated by the bandwidth of the port and cable you use.
🏆 Hardware Spotlight: Cevaton Portable Displays
If you are purchasing a portable laptop monitor, understanding your primary use case determines the Hz you need. The Cevaton ecosystem offers distinct solutions:
- For Office & Remote Productivity: The Cevaton T2 PRO (60Hz IPS). Why 60Hz? Because pushing 144Hz via USB-C drains laptop batteries rapidly. For coding, spreadsheets, and web browsing, a rock-solid 60Hz panel with 100W PD Pass-Through charging is the ultimate ergonomic choice, ensuring your laptop doesn't die in a coffee shop.
- The Golden Rule for Portable Screens: Always use the Full-Featured USB-C cable provided in the box. A standard charging cable from your phone cannot transmit video data, leading to a "No Signal" error.
Section 4: Masterclass: Why is My 144Hz Monitor Stuck at 60Hz?
This is the most common support ticket in the display industry. If your Windows settings simply do not show a 144Hz or 165Hz option despite owning a gaming monitor, diagnose the issue using these four pillars:
🚨 1. The Cable Bandwidth Bottleneck (The #1 Culprit)
Not all cables are created equal. An older HDMI 1.4 cable simply does not have the physical bandwidth to carry a 1440p or 4K signal at 144Hz.
The Fix: Ditch the old HDMI. Use a DisplayPort 1.4 cable or an HDMI 2.1 certified ultra-high-speed cable. If using a laptop, ensure you are using a USB-C to DisplayPort cable capable of 32Gbps data transfer.
🚨 2. The "Duplicate Displays" Trap
If you have a dual monitor setup where one screen is 60Hz (like a basic laptop screen) and the external monitor is 144Hz, Windows will restrict both monitors to the lowest common denominator if you have them set to "Duplicate these displays."
The Fix: Press Win + P and select "Extend". Now you can set the laptop to 60Hz and the external monitor to 144Hz independently.
🚨 3. Outdated GPU Drivers
Windows generic display drivers cannot unlock high refresh rates.
The Fix: Open NVIDIA GeForce Experience, AMD Adrenalin, or Intel Arc Control and perform a "Clean Installation" of the latest graphics drivers.
Section 5: How to Physically Test Your Refresh Rate
Just because Windows says you are running at 144Hz doesn't mean your monitor isn't dropping frames. To visually confirm your monitor is operating correctly, professionals use the Blur Busters UFO Test.
- Open your web browser (Chrome or Edge recommended).
- Navigate to TestUFO.com.
- The site will automatically detect and verify your exact refresh rate in real-time. You will see flying UFOs moving across the screen; the top UFO represents your maximum Hz. If the 144Hz UFO looks blurry or skips, your monitor is suffering from "frame skipping," indicating a faulty cable or overclocking issue.
Section 6: Frequently Asked Questions (FAQ)
Q1: Does a higher refresh rate drain laptop battery faster?
A: Yes, significantly. Pushing 120Hz or 144Hz requires the GPU to work twice as hard as 60Hz. If you are working untethered in a cafe with a travel monitor for laptop, we highly recommend locking both your laptop and portable screen to 60Hz to maximize battery life.
Q2: What is the ideal refresh rate for an office workstation?
A: For spreadsheets, coding, and general web browsing, 60Hz is the global standard. Displays like the Cevaton N2 and T2 PRO utilize 60Hz IPS panels specifically to deliver superior color accuracy (100% sRGB) and low power consumption without the unnecessary cost of gaming-grade refresh rates.
Q3: How do I check the maximum refresh rate my monitor supports?
A: The most accurate method is to check the manufacturer's official specifications page (or the physical manual inside the box). Keep in mind that a monitor advertised as "144Hz" might only achieve that speed via DisplayPort, while its HDMI port might be hardware-locked to 120Hz or 60Hz.
Q4: Can I overclock my monitor's refresh rate?
A: Some high-end gaming monitors allow a 5-15Hz overclock via their OSD (On-Screen Display) menu. However, using software like CRU (Custom Resolution Utility) to force a standard 60Hz monitor to run at 75Hz can lead to severe hardware damage, screen artifacts, and voided warranties. We do not recommend it for portable laptop monitors.
Conclusion: The Smoother Path Forward
Checking and optimizing your monitor's refresh rate is the single most cost-effective "upgrade" you can perform on your computer. Whether you are aiming for butter-smooth headshots in competitive gaming or simply want your mouse cursor to glide across your secondary display without jittering, ensuring your operating system, cables, and hardware are perfectly aligned is critical.
Remember, if you are building a mobile command center, balance is key. Pairing a high-end laptop with an intelligently designed, power-efficient laptop screen extender like the Cevaton T2 PRO guarantees that your workflow remains smooth, stable, and untethered.
