Windows 11 Insider Canary Channel build 25941 adds a dynamic refresh rate toggle and more

Published on

Microsoft has released a new Windows 11 build for members of the Windows Insider Program in the Canary channel. The build number is 25941 and it has a few small additions, along with a list of known issues.

Here is the changelog:

Changes and Improvements


In this Insider Preview build, you may notice that there have been some changes in the advanced display settings page via Settings > System > Display > Advanced display. Dynamic refresh rate can now be enabled via a toggle. After being enabled, Windows will then dynamically adjust the refresh rate up to the selected rate to help save power. Click here for more information on Dynamic refresh rate.

Additionally, we’ve made small changes to help bring awareness to limitations (related to the display or the cable being used) that may not allow you to set a high refresh rate while being on a high display resolution. When selecting a refresh rate, you may notice some refresh rates will show an asterisk. That means that in order to select that specific refresh rate, the display resolution will need to be changed to one that supports the selected refresh rate. This behavior happens when there are limitations due to the cable or the display’s capabilities and is not new, but we wanted to make sure you were aware of it.


Building off the Cast improvements introduced with Build 25926, we have updated the Cast flyout in Quick Settings with additional support for you in case you face any trouble discovering nearby displays, fixing connections, and more.

The graph at the top of the Power & Battery page in Settings has been removed. Insiders can continue to see a graph of battery usage in the battery usage section further down the page. The Power & battery settings page is also no longer broken up by “Power” and “Battery” sections.
