A higher refresh rate display, like 120Hz or higher, significantly enhances the visual experience on your laptop. Everything from scrolling through web pages to playing fast-paced games becomes noticeably smoother and more responsive. While many gaming laptops come with high refresh rate screens, it’s not always automatically enabled, and sometimes you might want to force it for specific applications. This comprehensive guide will walk you through the steps to ensure your laptop display operates at its maximum refresh rate potential.
Understanding Refresh Rate and Its Benefits
Refresh rate, measured in Hertz (Hz), indicates how many times per second your display redraws the image. A 60Hz display refreshes the image 60 times a second, while a 120Hz display refreshes it 120 times. The higher the refresh rate, the smoother the perceived motion, reducing motion blur and making visuals appear crisper, especially during fast-paced action.
The benefits extend beyond gaming. A 120Hz screen reduces eye strain during prolonged use, makes everyday tasks like browsing feel more responsive, and enhances the overall viewing pleasure for videos and movies. A smoother experience contributes to improved productivity and reduced fatigue.
Checking Your Laptop’s Display Capabilities
Before attempting to force a 120Hz refresh rate, it’s crucial to confirm that your laptop’s display actually supports it. Simply assuming it does can lead to frustration. Many laptops, particularly budget-friendly models, are limited to the standard 60Hz.
The specifications of your laptop will usually state the refresh rate of the screen. If you have the model number of your laptop, searching online for its specifications is the easiest route. Look for phrases like “120Hz display,” “high refresh rate screen,” or check the detailed specifications under the display section.
If you can’t find the official specifications, there are software methods to help determine your display’s capabilities.
Using Windows Display Settings
Windows provides a built-in method to check and adjust the refresh rate.
- Right-click on your desktop and select “Display settings.”
- Scroll down and click on “Advanced display settings.”
- Select your display if you have multiple monitors connected.
- Click on “Display adapter properties for Display [Number].”
- Go to the “Monitor” tab.
- Here, you will see a dropdown menu for “Screen refresh rate.” This dropdown shows the refresh rates your display currently supports. If 120Hz is listed, proceed to the next steps. If it’s not listed, your laptop display might not be capable of 120Hz.
Utilizing Third-Party Software
Specialized software can sometimes provide more detailed information about your display’s capabilities than the Windows settings alone. Programs like MonitorInfoView (a free utility) can read the Extended Display Identification Data (EDID) of your monitor, which contains information about supported resolutions and refresh rates.
If MonitorInfoView lists 120Hz as a supported refresh rate even though it doesn’t appear in the Windows settings, it’s possible that you need to update your graphics drivers or use a custom resolution utility.
Enabling 120Hz Refresh Rate in Windows
Once you’ve confirmed that your laptop’s display supports 120Hz and it’s not already enabled, you can proceed to enable it.
Through Display Settings (Revisited)
As outlined in the “Checking Your Laptop’s Display Capabilities” section, the primary method for changing the refresh rate is through the Windows Display Settings. Follow those steps again, ensuring you select 120Hz from the “Screen refresh rate” dropdown menu. Apply the changes and confirm that the display looks correct.
Sometimes, even if 120Hz is listed, selecting it might not automatically apply. This can be due to driver issues or other software conflicts. If you encounter problems, try restarting your laptop after applying the change.
Using Graphics Control Panel (NVIDIA or AMD)
If the Windows display settings don’t offer the desired refresh rate, or if you experience issues applying the changes, using your graphics card’s control panel is another option. Most modern laptops utilize either NVIDIA or AMD graphics cards.
NVIDIA Control Panel
- Right-click on your desktop and select “NVIDIA Control Panel.”
- Navigate to “Display” > “Change resolution.”

- Right-click on the .exe file and select “Properties.”
- Go to the “Compatibility” tab.
- Check the box that says “Disable fullscreen optimizations.”
- Click “Apply” and then “OK.”
This can sometimes resolve issues where the game is not running at the correct refresh rate, even though it’s set in the Windows or graphics control panel settings.
Forcing 120Hz in Specific Applications
Sometimes, you might want to force 120Hz only in specific applications, such as games. Even if the global refresh rate is set to 120Hz, some applications might default to a lower refresh rate.
Using Game Settings
Many games have built-in settings to control the refresh rate. Check the game’s video settings menu and ensure that the refresh rate is set to 120Hz or the highest available option. Setting the refresh rate within the game itself is the most reliable way to ensure it runs at the desired rate.
Using Launch Options (Steam)
For games on Steam, you can sometimes use launch options to force a specific refresh rate.
- Right-click on the game in your Steam library and select “Properties.”
- Click on “Set Launch Options.”
- Enter the following command:
-refresh 120 - Click “OK” and launch the game.
This command tells the game to run at a 120Hz refresh rate. Note that this method might not work for all games.
Using Custom Resolution Utility (CRU)
Custom Resolution Utility (CRU) is a powerful tool for advanced users that allows you to create custom resolutions and refresh rates. Use this tool with caution, as incorrect settings can damage your display.
CRU allows you to define specific resolutions and refresh rates that might not be available through the Windows or graphics control panel settings. If you’re comfortable with advanced settings and understand the risks involved, CRU can be a useful tool for forcing 120Hz in specific applications.
Verifying the Refresh Rate In-Game
After making changes to force 120Hz, it’s essential to verify that the refresh rate is actually being applied in-game.
Using In-Game FPS Counters
Many games have built-in FPS (frames per second) counters that can also display the refresh rate. Enable the FPS counter in the game’s settings menu. If the counter shows a value close to 120 FPS and the display looks smooth, it’s likely that the game is running at 120Hz.
Using Third-Party FPS Monitoring Software
Programs like MSI Afterburner with RivaTuner Statistics Server (RTSS) can display an overlay with detailed information about your system’s performance, including the FPS and refresh rate. This is a more reliable method than relying solely on in-game FPS counters.
Final Thoughts
Achieving a 120Hz refresh rate on your laptop can significantly improve your visual experience, making everything from gaming to everyday tasks smoother and more enjoyable. By understanding your laptop’s display capabilities, adjusting the Windows and graphics control panel settings, and troubleshooting common issues, you can unlock the full potential of your display. Remember to verify the refresh rate in-game to ensure that your settings are being applied correctly. Enjoy the smoother visuals!
Why doesn’t my laptop automatically run at 120Hz even though the screen supports it?
Some laptops, particularly those with variable refresh rate (VRR) technologies like AMD FreeSync or NVIDIA G-Sync, might not default to the maximum refresh rate to conserve battery life. The operating system, by default, often chooses a lower refresh rate, like 60Hz, to reduce power consumption. This is especially true when the laptop is running on battery power instead of being plugged into a power outlet.
To ensure your laptop runs at 120Hz, you’ll typically need to manually adjust the display settings within your operating system. This involves navigating to the display settings panel and selecting the desired refresh rate from the available options. You might also need to disable any power-saving features that are interfering with the higher refresh rate setting.
How do I change the refresh rate in Windows 10 or Windows 11?
To change the refresh rate in Windows 10, right-click on the desktop and select “Display settings”. Scroll down to “Advanced display settings” and click on it. Choose the correct display if you have multiple monitors, then click on “Display adapter properties for Display [number]”. In the new window, go to the “Monitor” tab and select “120 Hertz” (or the supported refresh rate) from the “Screen refresh rate” dropdown menu. Click “Apply” and then “OK”.
In Windows 11, right-click on the desktop and select “Display settings”. Scroll down and click on “Advanced display”. Choose the correct display if you have multiple monitors, then click on “Display adapter properties”. A new window will open. Navigate to the “Monitor” tab and select the desired refresh rate (120Hz or the highest supported) from the dropdown menu. Apply the changes by clicking “Apply” and then “OK”.
What if 120Hz isn’t listed as an option in my display settings?
If 120Hz isn’t appearing as an available option in your display settings, the first thing to check is your graphics card drivers. Outdated or corrupted drivers can often prevent your laptop from recognizing and utilizing the full capabilities of your display. Try updating to the latest drivers from the manufacturer’s website (NVIDIA, AMD, or Intel).
Another potential issue is the display cable connection (if using an external monitor). Ensure you’re using a cable that supports the desired refresh rate and resolution, such as HDMI 2.0 or DisplayPort. For built-in laptop displays, this isn’t usually the problem, but it’s still worth verifying that the laptop’s hardware supports 120Hz at the current resolution; a specific resolution might require reduced refresh rate.
Will forcing 120Hz reduce my laptop’s battery life?
Yes, running your laptop display at 120Hz will generally consume more power compared to a lower refresh rate like 60Hz. This is because the display is refreshing twice as often, requiring the graphics card and display panel to work harder, thus drawing more power from the battery.
The extent of the battery life reduction will depend on various factors, including the specific laptop model, the type of content being displayed (static images vs. dynamic games), and other power-saving settings. Expect a noticeable decrease in battery runtime, especially when performing graphically intensive tasks or running on battery power. Consider switching back to 60Hz when battery life is a priority.
Can I damage my laptop by forcing it to run at 120Hz?
Generally, forcing your laptop to run at 120Hz will not cause damage, as long as the screen and graphics card are designed to support that refresh rate. The system will usually prevent you from selecting a refresh rate that the hardware cannot handle. However, prolonged operation near the limits of the hardware capabilities could potentially lead to increased heat generation.
If you experience visual artifacts, screen flickering, or instability after setting the refresh rate to 120Hz, it may indicate that the hardware is not fully compatible or that there are driver issues. In such cases, it’s best to revert to a lower, more stable refresh rate to prevent potential problems. Monitoring the laptop’s temperature while running at 120Hz can also provide insight into whether the hardware is being pushed too hard.
Does forcing 120Hz improve performance in games?
Setting your laptop’s refresh rate to 120Hz can significantly enhance the gaming experience if your laptop’s hardware can consistently deliver frame rates above 60 frames per second (FPS). A higher refresh rate reduces motion blur and provides smoother visuals, leading to improved responsiveness and a more immersive gameplay experience.
However, simply setting the refresh rate to 120Hz won’t automatically increase your game’s FPS. Your laptop’s CPU and GPU must be powerful enough to render frames at a rate that matches or exceeds the refresh rate. If your game’s FPS consistently remains below 60, you won’t fully benefit from the 120Hz setting. In those scenarios, you might want to lower the game’s graphics settings.
What are the benefits of using 120Hz outside of gaming?
While the most noticeable benefits of a 120Hz display are often associated with gaming, there are also advantages for general productivity and everyday use. Scrolling through web pages and documents appears smoother, reducing eye strain and making text easier to read, especially for those sensitive to screen flicker.
The increased responsiveness of a 120Hz display can also make interactions with the operating system feel more fluid and instantaneous. This is particularly noticeable when dragging windows, using animations, and performing other visual tasks. Although the difference may be subtle compared to the impact on gaming, it contributes to a more pleasant and comfortable overall user experience.
