Changes and Improvements

[Graphics]

• We have improved refresh rate logic to allow different refresh rates on different monitors, depending on the refresh rate for each monitor and content shown on the screen. This will help most with refresh rate-dependent multitasking, like playing a game and watching a video at the same time.

• While a Dynamic Refresh Rate (DRR) is selected and Battery saver is also enabled, Windows will remain at the lower refresh rate and not switch to the higher rate until after Battery saver is disabled.

Fixes for known issues

• The issue that resulted in some Windows Insiders in the Canary Channel on ASUS devices or PCs with ASUS motherboards has been resolved and these Insiders should receive this flight.

• Ethernet-connected devices will no longer lose network connectivity after updating to this build.
