Choose the output mode
Always On converts non-HDR content to HDR output. On When Supported leaves that content in SDR. Choose the behavior you want for the console.

GTA 6 HDR on PS5: console display setup
Prepare your PS5 display with Sony’s HDR output and calibration controls. Choose an output mode and check your TV without guessing GTA VI brightness values.
Short answer
Prepare PS5’s console-wide HDR output under Settings > Screen and Video > Video Output. Choose HDR for output behavior and Adjust HDR for calibration. These controls do not establish a GTA VI-specific brightness setting.
Calibrate for your display
Image quality depends on the connected display. Follow its instructions and Sony’s calibration screens; a brightness number copied from another TV is not a reliable starting point.

If HDR will not enable
Use the diagnostics linked from Sony’s HDR support page. For a dark or washed-out picture, check console output and TV settings one at a time. GTA VI-specific HDR menus and values remain unverified.
