PS5 HDR Brightness Lockout on Samsung TV – Marathon Server Slam

While playing Marathon Server Slam on PS5, my Samsung TV switches to maximum HDR brightness and locks at 100 percent. Once this occurs: • TV brightness becomes unchangeable • Adjusting television settings has no effect • The only solution is closing the game or disabling HDR on PS5 This creates significant eye strain and makes the game uncomfortable to play unless the room is extremely bright. ⸻ My PS5 Settings • HDR: Always On • Deep Color Output: Automatic • RGB Range: Automatic Disabling HDR restores brightness control, but I do not want to toggle system settings every time I launch specific games. ⸻ Pattern Observed This issue occurs in certain games, including: • Marathon Server Slam • Arc Raiders • Control • Call of Duty 7 • Need for Speed Unbound However, other HDR games do not cause this issue: • Overwatch • Deep Rock Galactic • Marvel Rivals • Genshin Impact This suggests the issue may be tied to how certain games handle HDR metadata or brightness mapping. I would like to: • Play with HDR enabled • Maintain manual brightness control on my TV • Avoid switching system settings per title It is significant enough to impact play comfort and accessibility. If this is related to HDR implementation differences, any clarification or acknowledgment would be appreciated. Thank you.
