If you find some of the Granblue Fantasy Versus: Rising stages look too dark while other levels look a little too dark, then you might need to change the brightness level. To find out how you can do in this 2.5D fighting game, you can check out this tutorial from Seeking Tech.
1. From the main menu, switch over to the Options tab and then select Battle Settings.
2. In the pop-up menu, you should find the Brightness slider with the following description:
Adjust the brightness of the screen.
3. The default value of the Brightness slider is 25. Use the left analog or directional button to change it anywhere from a value of 0 to 5.
4. Test out the new brightness in the game to see if it looks right. If it still looks off, then you can return to the Options > Battle Settings screen and then re-adjust the brightness level.
5. You can also adjust the HDR brightness output on your PC, PS4 or PS5 to see if that makes any difference.
