Why isnʼt my monitor showing 144hz?

**Why isnʼt my monitor showing 144hz?**

If you recently purchased a high-refresh-rate monitor and can’t seem to get it to display at a 144Hz refresh rate, you might be left wondering why. A smooth and fluid 144Hz experience can greatly enhance your gaming or even general computing activities, but various factors can prevent your monitor from achieving this optimal refresh rate. In this article, we will dive into the possible reasons why your monitor isn’t displaying 144Hz, as well as provide solutions to help you unlock the full potential of your display.

First and foremost, the most common reason behind your monitor not showing 144Hz is the use of an incompatible cable. To achieve a 144Hz refresh rate, you need to ensure that you are using a cable that supports such high refresh rates. The DisplayPort cable is the most reliable choice, as it can handle the bandwidth required for 144Hz. Using an HDMI cable may limit the refresh rate to 60Hz, so try swapping out the cable for a DisplayPort one if you haven’t already.

Another potential hurdle to achieving 144Hz is the settings in your graphics card control panel. Many graphics cards have default settings that limit the refresh rate to prevent compatibility issues with older monitors. To overcome this, open your graphics card control panel and navigate to the display settings. From there, adjust the refresh rate to 144Hz manually.

Sometimes, the issue lies in your monitor’s settings itself. **Double-check the monitor settings to ensure that it is set to run at a 144Hz refresh rate**. Depending on the monitor model, the option to change the refresh rate may be under different menus, so explore through the settings and select the highest refresh rate available.

In certain cases, your monitor’s firmware might need an update to unlock the 144Hz capability. Check the manufacturer’s website for any available updates for your specific monitor model. Updating the firmware can often resolve compatibility issues and allow your monitor to display at 144Hz.

If you have dual monitors connected to your computer, it could cause limitations in achieving a 144Hz refresh rate. Some graphics cards have limitations when running multiple monitors at high refresh rates, so try disconnecting the secondary monitor temporarily to see if it affects the refresh rate on your main monitor.

Furthermore, outdated graphics drivers can hinder the proper functioning of your monitor at higher refresh rates. Ensure that you have the latest drivers for your graphics card installed. You can usually find the latest drivers on the manufacturer’s website, available for download. Installing the updated drivers may fix any compatibility issues affecting the refresh rate.


1. How can I check the refresh rate my monitor is currently set to?

To check your monitor’s refresh rate, right-click on the desktop, select “Display settings,” then click on “Advanced display settings.” Here, you can view and adjust the refresh rate.

2. Can a low-quality HDMI cable support 144Hz?

Typically, no. Low-quality HDMI cables may lack the necessary bandwidth to support a 144Hz refresh rate. It is recommended to use a DisplayPort cable instead.

3. Can my graphics card support 144Hz?

Your graphics card needs to support a 144Hz refresh rate. Ensure that your graphics card is capable of handling such high refresh rates.

4. Why is my monitor displaying 144Hz, but the games still look like they’re running at a lower refresh rate?

Double-check that the game settings themselves are set to the desired refresh rate. Some games have their own refresh rate settings which may differ from the system settings.

5. Can overclocking my monitor enable 144Hz?

In some cases, yes. Overclocking your monitor beyond its native refresh rate may unlock higher refresh rates, but it is not guaranteed and can potentially damage your monitor.

6. Can a faulty cable prevent my monitor from displaying 144Hz?

Yes, faulty cables can limit the refresh rate. Ensure that the cable you are using is certified for high refresh rates and is in good condition.

7. Will upgrading my computer’s hardware allow my monitor to display at 144Hz?

Upgrading your computer’s hardware, particularly the graphics card, can increase the likelihood of achieving 144Hz. However, other factors such as the monitor’s compatibility and settings also play a significant role.

8. Why does my monitor flicker when set to 144Hz?

Flickering at high refresh rates can be caused by a variety of factors, such as an incompatible cable, outdated drivers, or a faulty monitor. Troubleshoot these areas to find the root cause of the flickering issue.

9. Why does my monitor display 144Hz in the Windows settings, but not in games?

Some games have their own internal settings that need to be adjusted to match the desired refresh rate. Make sure to check the in-game settings and set them accordingly.

10. Can using a different video output affect my monitor’s refresh rate?

Yes, different video outputs have different limitations regarding refresh rates. For example, using an HDMI output may limit the refresh rate to 60Hz. Always prioritize using a DisplayPort connection for optimal high refresh rate support.

11. Can using multiple monitors affect the overall refresh rate?

Running multiple monitors can affect the refresh rate, particularly if the graphics card has limitations when multiple monitors are connected. Try disconnecting the additional monitors to see if it improves the refresh rate on your primary monitor.

12. Is a 144Hz refresh rate necessary for all users?

A 144Hz refresh rate is not necessary for all users. It is primarily beneficial for gamers and those who require smooth motion, such as graphic designers or video editors. For general computing, a 60Hz refresh rate is typically sufficient.
