RE: New Dell Inspiron 15 7577 4k resolution windows animation lags but not while gaming.

Thank you for your message.

This could be an issue caused by an update or a driver.

Open device manager – expand display adapter- right click on the graphic driver & click on uninstall (do not check the box that says delete driver) & restart the computer.

This will refresh the driver.  Complete all Windows updates & check if the issue persists.

For my reference, please click on my Dell username & send a private message with the service tag, registered name & email address.
