Hello! Thank you for reaching out! @ddaniel51 is correct! I just also tested it on my computer and when switch hz my monitors go blank also I tried from 60 to 75 and from 165 to 120 and every time my monitor would have a blank screen for a second or two. As long as its coming back it will be fine. Unless you are using a custom resolution or refresh rate combination. Then the screen will still blank until the monitor goes back to the original combination.
