Have you recently purchased a 144Hz monitor, excited to experience smoother visuals in your games and everyday tasks, only to find that you’re stuck at a lower refresh rate like 60Hz? It’s a frustrating situation, but thankfully, it’s often solvable. This article will guide you through the common reasons why you might be struggling to achieve that desired 144Hz refresh rate and provide detailed troubleshooting steps.
Understanding Refresh Rate and its Importance
Before diving into troubleshooting, let’s quickly recap what refresh rate is and why it matters. Refresh rate, measured in Hertz (Hz), refers to how many times per second your monitor updates the image displayed. A 60Hz monitor updates the image 60 times a second, while a 144Hz monitor updates it 144 times a second.
A higher refresh rate translates to smoother motion, reduced motion blur, and a more responsive feel, especially noticeable in fast-paced games. This is why gamers often prioritize high refresh rate monitors. However, simply owning a 144Hz monitor doesn’t automatically guarantee you’ll be running at that refresh rate. Several factors need to be aligned for everything to work correctly.
Common Culprits: Identifying the Bottlenecks
Several factors can prevent your monitor from running at its advertised 144Hz refresh rate. Let’s explore the most common causes, starting with the simplest and working our way towards more complex issues.
The Cable Connection: HDMI vs. DisplayPort
The type of cable you use to connect your monitor to your computer is crucial. Not all cables are created equal, and some may not have the bandwidth necessary to support 144Hz at higher resolutions.
HDMI limitations: While HDMI has evolved over the years, older versions may not support 144Hz, particularly at resolutions like 1440p or 4K. HDMI 1.4, for instance, might struggle to deliver 144Hz at 1080p, and higher resolutions are almost certainly out of the question. Even newer HDMI versions may require specific settings on your monitor and graphics card to enable their full potential.
DisplayPort advantages: DisplayPort is generally the preferred connection for high refresh rates and resolutions. DisplayPort 1.2 and above typically provide ample bandwidth for 144Hz at 1080p and 1440p. DisplayPort 1.4 offers even more bandwidth, making it suitable for 144Hz at 4K and even higher refresh rates.
Solution: Ensure you’re using a DisplayPort cable if possible. If you must use HDMI, make sure it’s a relatively recent version (HDMI 2.0 or higher) and check your monitor’s manual to confirm that its HDMI ports support the desired resolution and refresh rate. Try a different cable, even if you believe the current one should be compatible, as cable quality can vary.
Graphics Card Capabilities: Can Your GPU Handle It?
Your graphics card (GPU) is the engine that drives your monitor. If your GPU isn’t powerful enough or its drivers are outdated, it can limit the refresh rate you can achieve.
Sufficient power: Older or lower-end graphics cards might simply lack the horsepower to render frames quickly enough to reach 144Hz, especially at higher resolutions and graphics settings in games.
Driver updates: Outdated or corrupted graphics drivers can cause all sorts of issues, including limiting your refresh rate.
Solution: Ensure your graphics card meets the minimum requirements for running games at your desired resolution and refresh rate. Update your graphics drivers to the latest version from the NVIDIA or AMD website (depending on your GPU). A clean driver installation can sometimes resolve conflicts. To perform a clean install, use the driver uninstaller provided by the GPU manufacturer, or a third-party tool like DDU (Display Driver Uninstaller).
Monitor Settings: Configuration is Key
Even if your cable and GPU are capable, your monitor’s settings might be configured incorrectly, preventing it from running at 144Hz.
On-Screen Display (OSD) settings: Many monitors have settings that can limit the refresh rate, such as “Eco Mode” or specific input settings.
Windows display settings: Windows itself needs to be configured to use the correct refresh rate for your monitor.
Solution: Access your monitor’s On-Screen Display (OSD) menu (usually by pressing buttons on the monitor itself) and look for any settings that might be limiting the refresh rate. Disable any power-saving modes and ensure the input is configured correctly.
Next, in Windows, right-click on your desktop and select “Display Settings”. Scroll down to “Advanced display settings” and select your monitor. Under “Refresh rate,” choose 144Hz from the drop-down menu. If 144Hz is not available, it indicates a problem with the cable, GPU, or drivers.
Operating System and Software Conflicts
Sometimes, the problem isn’t hardware-related but stems from software conflicts or operating system limitations.
Outdated Windows version: Older versions of Windows might not fully support high refresh rates.
Conflicting software: Certain applications can interfere with display settings.
Solution: Ensure you’re running the latest version of Windows. Check for updates in Windows Update. Temporarily disable any potentially conflicting software, such as third-party display management tools, to see if that resolves the issue.
Resolution Limitations
The resolution you’re trying to run can significantly impact the refresh rate you can achieve.
Higher resolutions demand more bandwidth: Running at 4K resolution requires significantly more bandwidth than 1080p, potentially exceeding the capabilities of your cable or GPU, even if they support 144Hz at lower resolutions.
Solution: Try lowering the resolution to see if you can achieve 144Hz. If you can, it indicates that your cable or GPU might be struggling to handle the higher resolution at the desired refresh rate.
Monitor Compatibility and Specifics
It’s important to consider the specific capabilities of your monitor. Not all 144Hz monitors are created equal, and some might have limitations.
Overclocking limitations: Some monitors advertise a 144Hz refresh rate, but this is only achievable through overclocking, which might require specific settings and might not be stable.
FreeSync or G-Sync requirements: If your monitor supports AMD FreeSync or NVIDIA G-Sync, ensure that these features are properly enabled in your graphics card drivers and monitor settings. Sometimes, these features can interfere with achieving the maximum refresh rate if not configured correctly.
Solution: Consult your monitor’s manual to understand its specific capabilities and requirements for achieving 144Hz. Check for any specific settings that need to be enabled or disabled. If your monitor supports FreeSync or G-Sync, experiment with enabling and disabling these features to see if it resolves the issue.
Multiple Monitor Setups
Having multiple monitors connected to your computer can sometimes cause conflicts and limit the refresh rate of your primary monitor.
Bandwidth limitations: Each monitor consumes bandwidth, and having multiple high-resolution or high-refresh-rate monitors can strain your GPU’s capabilities.
Driver conflicts: Sometimes, drivers struggle to manage multiple displays correctly.
Solution: Try disconnecting all monitors except the one you want to run at 144Hz. If this resolves the issue, it indicates that your GPU might be struggling to handle multiple displays at the desired refresh rates. Experiment with different configurations and driver settings to find a stable setup.
Hardware Conflicts and Motherboard Issues
In rare cases, the issue might be related to hardware conflicts or limitations of your motherboard.
PCIe slot limitations: Ensure your graphics card is installed in the correct PCIe slot, preferably the one that provides the full bandwidth (usually the top slot).
Motherboard compatibility: Older motherboards might not fully support the latest graphics cards or high refresh rates.
Solution: Consult your motherboard’s manual to ensure your graphics card is installed in the correct PCIe slot. Consider updating your motherboard’s BIOS to the latest version, as this can sometimes improve hardware compatibility.
Step-by-Step Troubleshooting Guide

Why isn’t 144Hz showing up as an option in my display settings?
The most common reason a 144Hz refresh rate isn’t available is that your monitor isn’t properly connected. To achieve 144Hz, you generally need to use a DisplayPort cable or, in some cases, a high-quality HDMI 2.0 cable. Older HDMI versions and VGA or DVI connections simply don’t have the bandwidth to support such high refresh rates, especially at higher resolutions like 1440p or 4K. Double-check your cable and ensure it’s securely plugged into both your monitor and your computer’s graphics card. Also, verify your monitor and graphics card both support the desired resolution and refresh rate combination.
Beyond the cable itself, your computer might not be recognizing the monitor’s capabilities correctly. Make sure you have the latest drivers installed for your graphics card. Outdated drivers often lead to compatibility issues and prevent you from accessing the full range of features your monitor offers. Furthermore, some monitors require you to manually enable the higher refresh rate within the monitor’s on-screen display (OSD) menu. Consult your monitor’s manual for specific instructions on how to enable 144Hz or overclock the refresh rate, if available.
Is my HDMI cable capable of 144Hz?
Not all HDMI cables are created equal. Older HDMI standards, such as HDMI 1.4, often have limitations in terms of bandwidth, making it difficult or impossible to achieve 144Hz refresh rates at higher resolutions like 1080p or 1440p. To reliably support 144Hz over HDMI, you generally need an HDMI 2.0 or, ideally, an HDMI 2.1 cable. These newer versions offer significantly increased bandwidth, enabling them to handle the data throughput required for high refresh rates and resolutions.
Look for HDMI cables specifically advertised as “High Speed” or “Ultra High Speed,” as these are typically compliant with HDMI 2.0 or 2.1 standards. It’s also worth checking your monitor and graphics card specifications to confirm their HDMI port versions. While an HDMI 2.1 cable will work with an HDMI 2.0 port (and vice-versa), you’ll be limited to the capabilities of the lower version. If you’re unsure, using a DisplayPort cable is generally a safer bet for achieving 144Hz.
I’m using DisplayPort, why still no 144Hz option?
Even with a DisplayPort connection, there can be reasons why you’re not seeing the 144Hz option. First, ensure you’re using a DisplayPort cable that meets the minimum requirements for your desired resolution and refresh rate. While DisplayPort generally has ample bandwidth, damaged or low-quality cables can still cause issues. Try a different DisplayPort cable, ideally one that’s certified as DisplayPort 1.2 or higher, to rule out a cable problem.
Another possibility is that your graphics card driver isn’t correctly detecting the monitor’s capabilities. Try uninstalling and reinstalling your graphics card drivers, making sure to download the latest version directly from the manufacturer’s website (Nvidia, AMD, or Intel). During the driver installation process, you might also find an option to perform a “clean install,” which removes any residual driver files that could be interfering with the proper detection of your monitor’s refresh rate. After reinstalling the drivers, reboot your computer and check your display settings again.
How do I change my refresh rate in Windows 10/11?
Changing your refresh rate in Windows 10 or 11 is a straightforward process. First, right-click on an empty area of your desktop and select “Display Settings”. Scroll down to the “Advanced display settings” link and click on it. Then, select your monitor from the dropdown menu (if you have multiple monitors). You should then see a “Choose a refresh rate” dropdown menu. Select 144Hz from the list and click “Apply”.
If you don’t see the “Advanced display settings” link, you can also access the refresh rate settings through the graphics card control panel. For Nvidia, open the Nvidia Control Panel and navigate to “Display” > “Change resolution”. For AMD, open AMD Radeon Settings and go to “Display” > “Display Options”. From there, you should be able to select the desired refresh rate. After making the change, be sure to click “Apply” to save the settings. You may be prompted to confirm the change to prevent issues if the selected refresh rate is not supported.
My monitor supports 144Hz, but it’s greyed out in settings. What does that mean?
When the 144Hz option is greyed out in your display settings, it usually indicates that your system isn’t currently able to support that refresh rate under the existing configuration. This often points to a hardware limitation or a driver issue. Double-check that your monitor is connected using a DisplayPort cable or a high-quality HDMI 2.0 (or newer) cable. Ensure that the cable is securely connected to both your monitor and your graphics card. If the cable is loose or damaged, it might not be able to transmit the required bandwidth for 144Hz.
Another reason for the greyed-out option could be related to your graphics card driver. Make sure you have the latest drivers installed, as outdated or corrupted drivers can prevent you from accessing the full range of refresh rates supported by your monitor. Try uninstalling the current drivers and then downloading and installing the latest version from the manufacturer’s website (Nvidia or AMD). After updating the drivers, restart your computer and check if the 144Hz option is now available.
Could my integrated graphics be the problem?
Yes, your integrated graphics could definitely be the source of the issue. Most computers have both a dedicated graphics card (GPU) and integrated graphics (often built into the CPU). If your monitor is connected to a port on your motherboard instead of directly to your dedicated graphics card, you’re likely using the integrated graphics. Integrated graphics solutions are often not powerful enough to support 144Hz refresh rates, especially at higher resolutions.
The solution is to ensure that your monitor is connected to a video output port (DisplayPort or HDMI) directly on your dedicated graphics card. These ports are typically located on the back of your computer, often lower down in the case compared to the motherboard ports. Once you’ve connected your monitor to the dedicated graphics card, you may need to disable the integrated graphics in your BIOS settings to force your computer to use the dedicated card exclusively. Consult your motherboard’s manual for instructions on how to access and modify BIOS settings.
Will overclocking my monitor help me achieve 144Hz?
Overclocking your monitor might seem like a potential solution, but it’s usually not necessary if the monitor is already advertised as supporting 144Hz. Overclocking a monitor refers to pushing it beyond its officially rated refresh rate. While some monitors allow for a slight overclock, it’s generally only beneficial if you’re trying to achieve a refresh rate slightly higher than its default, and it can void your warranty. It’s also important to note that not all monitors are capable of being overclocked successfully, and attempting to do so can lead to image artifacts, instability, or even permanent damage.
If your monitor is supposed to support 144Hz and isn’t displaying the option, focus on resolving the underlying issue with cable connections, drivers, or graphics card compatibility first. Overclocking is more of a niche technique for enthusiasts and shouldn’t be the first step in troubleshooting a standard refresh rate problem. It’s also important to note that even if overclocking seems successful initially, the long-term stability of the monitor at the overclocked refresh rate isn’t guaranteed.
