If you are experiencing issues with your monitor's display when switching to 144Hz, you can try adjusting the settings manually. Here are the steps to do so:

• Check Your Display Information: Go to Start > Settings > System > Display > Advanced Display Settings. Here, you will find information such as your desktop resolution, active signal resolution, and refresh rate.
• Check the Refresh Rate: Ensure that your refresh rate is set to 144Hz. If not, change it to the desired rate.
• Select the Correct Refresh Rate: Click on Display Adapter Properties and then the Monitor tab. Use the drop-down menu to select 144 Hertz and click OK.
• For Windows 7 or 8: The steps are a bit different. Right-click on your desktop and select Screen Resolution. Then, go to Advanced Settings, navigate to the monitor tab, and choose 144Hz from the drop-down menu.
• Ensure Proper Connection: If you don't see a refresh rate of 144Hz, make sure your monitor is capable of displaying at that rate and is plugged into a display or DVI-D port. Other connections will not support 144Hz.

By following these steps, you can manually adjust your display settings to ensure that your monitor is running at the desired 144Hz refresh rate. If issues persist, you may need to consider other troubleshooting methods, such as updating your monitor drivers or checking your cable connections.

Update monitor drivers

Updating your monitor drivers can help ensure optimal performance and security for your device. While monitors are typically plug-and-play and automatically install compatible drivers, updating the drivers can be a troubleshooting step if you're experiencing issues with your monitor. Here's a guide on how to update your monitor drivers:

Monitors usually work without any issues as soon as you plug them in, and Windows automatically installs compatible drivers for peripherals like monitors. However, if you're facing problems such as blurry images, poor colour balance, no audio (for monitors with speakers), or if you can't select your native resolution, updating your monitor drivers might be a solution.

How to Update Monitor Drivers:

• Go to the manufacturer's website: Visit the support website of your monitor's manufacturer (e.g., Dell, HP, AOC, MSI).
• Find the driver download page: Navigate through the website to find the option to download drivers.
• Enter your monitor model: On the download page, enter the model name or number of your monitor.
• Download the driver: Download the driver for your specific monitor model. While you're there, you can also download the monitor's software to configure profiles, colours, brightness levels, etc.
• Run the downloaded driver: After downloading, run the driver file and follow the on-screen prompts to install it.
• Install manually if needed: If the downloaded file is an INF file and a few other potential files rather than an EXE (executable) file, you'll need to install it manually.
• Open Device Manager: Open the Windows Start Menu, type "Device Manager," and click to open it.
• Navigate to "Monitors": In Device Manager, find the "Monitors" section and locate your monitor. If you have multiple monitors showing up as "Generic PnP Monitor," disconnect all but the one you're updating.
• Update the driver: Right-click on the monitor you want to update, select "Update Driver," and then select "Browse my computer for drivers."
• Locate the INF file: Select "Browse" and find the folder containing the monitor driver's INF file. This is typically in the "Downloads" folder.

Troubleshooting:

If you encounter issues after updating your monitor drivers, you can roll back the drivers to their original state. Go to Device Manager, right-click on your monitor, and select "Uninstall Device." Then, restart your computer, and Windows will automatically reinstall the previous drivers.

Additionally, if you're still facing problems with your monitor, the issue may not be with the drivers. Check your graphics card driver, and research if others are experiencing similar issues with the same monitor or graphics card.

Try different cables

If you're experiencing glitches when switching your monitor to 144Hz, one potential solution is to try using different cables. Here are some detailed instructions and considerations regarding cable selection and troubleshooting:

Firstly, it's important to determine the type of cable currently being used. The most common types of cables used for monitors are HDMI, DisplayPort, DVI, and VGA. Each cable has different capabilities and limitations in terms of resolution, refresh rate, and compatibility. Identify which cable is currently connected to your monitor and ensure it supports the desired resolution and refresh rate.

If you're using an HDMI cable, try upgrading to a newer version if possible. Different versions of HDMI cables have varying capabilities. For example, while HDMI 1.4 can support up to 144Hz at 1080p resolution, HDMI 2.0 and higher versions can support higher resolutions at 144Hz.

For DisplayPort cables, ensure that you're using a DisplayPort 1.2 or higher cable. DisplayPort 1.2 and newer versions support resolutions up to 4K at 144Hz, while older versions may have limitations.

If you're using a DVI cable, it's important to distinguish between the different types. DVI-D Dual Link cables are commonly used for higher resolutions and refresh rates, while DVI-I cables are typically used for lower resolutions and refresh rates. Ensure that you're using the correct type of DVI cable for your monitor's specifications.

Additionally, consider the quality of the cable. Sometimes, a low-quality cable may not be able to maintain the signal integrity at higher refresh rates, leading to glitches or artifacts. Try using a high-quality cable that meets the latest standards to ensure optimal performance.

When testing with different cables, try using just one cable at a time. Some monitors may have multiple inputs, and using multiple cables simultaneously can sometimes lead to issues. Connect a single cable and test the monitor's performance at 144Hz to isolate any cable-related problems.

If you have access to different cables, try swapping them out one by one to identify if a specific cable is causing the issue. This will help narrow down whether the problem lies with a particular cable or with the monitor itself.

Lastly, ensure that the cables are properly connected and secured at both ends. Loose connections can sometimes lead to signal interruptions, resulting in glitches or flickering.

By trying different cables and considering their types, versions, and quality, you can effectively troubleshoot and potentially resolve the glitches experienced when switching your monitor to 144Hz.
