If you’re looking to change the brightness on your PlayStation 4, there are a few different ways to do so. You can use the main menu, go to Settings, and then select System. Here, you’ll be able to adjust the brightness level of your system. Alternatively, you can use the PS4’s built-in controls. To do this, first make sure that your PS4 is turned off and then press and hold down the power button until the light bar at the top of the console starts flashing white. Then release the power button and press and hold down both shoulder buttons (L2 and R2) until a menu appears on-screen. From here, you can select Settings and then System. Finally, adjust the brightness level by using the buttons on your controller. whichever method you choose, be sure to keep an eye on your screen’s brightness as it can easily become too bright or too dark if not adjusted correctly ..
