How can i make my screen brighter?

i' ve got a new pc, and everything is prefect for me except the screen. it is quite dimmed down. I cannot find a way to get the screen brighter. Can anyone tell me make it right?

you can set it in display setting

1. Control Panel, Power.
2. Select Change Plan Settings for the currently selected Power Plan,
or Adjust Display Brightness in the left Column. Both do the same thing.
3. Adjust the Brightness Slider under Battery or AC, depending on your current operation mode.
4. Click on Save Changes. The Brightness will change when the Save Changes button is clicked.
