You may notice that there may be something wrong with the HDR and/or brightness levels in the PlayStation 5 version of Honkai: Star Rail. To see how you can potentially fix these issues, you can take a look at this troubleshooting guide from Seeking Tech.
1. For the first step, you need to open the Settings menu of your PS5 and then go to Screen and Video > Video Output > Adjust HDR.
You should then follow the instructions that appear on the screen to calibrate the HDR brightness output of the console to your television set or monitor.
2. If the game still looks off, head over to the in-game Settings menu. From there, select HDR Moritor Mac Brightness Detection from the Graphics Settings tab.
You will be taken to a screen that let’s you calibrate the in-game brightness level.
3. You may also want to try playing Honkai: Star Rail without HDR enabled. To do so, turn off HDR on your PS5 as well as any HDR settings on your TV or monitor.
