Windows 10: Windows 11 Update Adds Support for Display Refresh Rates Above 1,000Hz

Microsoft's Windows 11 preview update KB5079391, released on March 26, adds support for display refresh rates above 1,000Hz, with internal documentation confirming the limit extends to 5,000Hz. The update was removed by Microsoft on March 27 after some installation issues were found. The improvements listed are expected to be available to users in a future release.

The update applies to Windows 11 versions 25H2, 24H2, and 26H1.

According to a post by Blur Busters, which was the first to identify support for 5,000Hz refresh rates, the site's founder Mark Rehjon helped convince Microsoft to raise the maximum refresh rate to that level. Microsoft's update notes simply mention support for "refresh rates above 1,000Hz" without specifying an upper limit.

Display And UI Changes In Windows 11 Update KB5079391


In addition to supporting higher refresh rates, the update brings several other changes related to display performance: It improves auto-rotation and HDR reliability, and enhances power efficiency for monitors connected via USB4

The update also introduces detailed image descriptions for Copilot and Copilot+ PCs when using Narrator. Additionally, the design of dialog boxes in the Accounts settings menu has been adjusted in the Other section.

Why Windows 11 Now Supports Up To 5,000Hz Refresh Rates


At CES 2026, Acer, AOC and Philips each revealed gaming monitors with 1,000Hz refresh rates that run at HD (720p) resolution. Blur Busters reports that several manufacturers plan to introduce 2,000Hz display panels by 2030. This suggests that the 5,000Hz limit in Windows 11 is meant to leave room for hardware advancements in the coming years.

Previous versions of Windows did not support refresh rates higher than 1,000Hz. Supporting these newer displays would require a future update to the operating system.

KB5079391 Installation Issues And Future Rollout


Microsoft pulled KB5079391 on March 27, just one day after its release, due to undisclosed installation failures. The company has not announced when a revised version will be available. Users who did not install the update before it was withdrawn will receive the included changes when Microsoft reissues it.

Refresh rate Problem

Hi Robert,

Thank you for posting your query in Microsoft Community.

Screen refresh rate is the rate at which the data displayed on screen is refreshed; it may be an image or some text document. Most of the users would like to set it to a higher rate but this also depends on the capacity of graphic
card and monitors. If the refresh rate is slow, the images on the display looks as flickering to the user eye and makes it uncomfortable to work.

Nowadays the latest monitors available in market will have minimum 60 Hz of refresh rate and it is very good option to set it to 70 Hz if you your monitor is compatible. Normally a high performance or quality monitors can reach
120 Hz of refresh rate. So I would suggest you to set your monitor refresh rate as higher as possible, below given steps describes how to access this feature on your Windows 8.1/10 PC.

• The default refresh rate setting is 60 Hertz (HZ); however, your monitor may support a higher setting. Check your manufacturer's documentation for information about the settings that your monitor supports.
• If you use a higher refresh rate, you can reduce the rate that your screen flickers; however, if you specify a refresh rate that is too high for your monitor, your screen may become unusable and your hardware may be damaged.
• Changes to the refresh rate affect all users that log on to the computer.

I would, as of now, suggest you to visit the computer manufacturer's support website and install the latest display and chipset drivers available for the latest operating system (currently it would be 8.1 in the list).

Hope this information is helpful. Please feel free to reply in case you face any other issues with Windows in future.

Hi Stephen,



Thank you for writing to Microsoft Community Forums.



I can imagine the inconvenience you are experiencing and will certainly help you in the right direction to fix the issue. However, I would appreciate if you could answer a few questions to narrow down the issue in order to provide you with better assistance.

1. What is the make and model of the computer?
2. What is the Windows 10 version and Build installed? (Type winver in Windows search/Run command) to provide the details.
   

The maximum refresh rate you can use depends on your monitor. If you have multiple monitors connected to your PC, each has its own separate refresh rate setting.



I would suggest you to try the below suggested methods and check if it helps.



Method 1

Check your Cables

Some monitors may have both HDMI and DisplayPort connections, but may be limited to a 60Hz refresh rate when connected via HDMI. In this case, you'd need to use a DisplayPort cable. Check your monitor's specifications or setup guide for more information.



If you're using HDMI, you'll want to ensure you're using a "high speed" HDMI cable and not an older "standard" HDMI cable.

In this scenario I would suggest you to replace the cable with the higher quality display and check the status of the issue.





Method 2

Update Graphics driver

Integrated graphics or older discrete graphics might not support your monitor's refresh rate. Be sure your graphics card supports the monitor's resolution and refresh rate. You need to update your Graphics drivers.

Refer the article
Update drivers in Windows 10 for the steps.



If the issue still persists, I suggest you to get in touch with the manufacturer support for the further assistance.
