Hi TAinNH, We appreciate you sharing details about the color and sharpness fluctuations you’ve experienced on your Samsung S95F TV. This behavior may be related to energy-saving features, AI-powered optimizations, or dynamic picture settings that automatically adjust screen brightness based on content and viewing environment. Please try disabling the following features: Settings > All Settings > General & Privacy > Power and Energy Saving > Brightness Optimization, Energy Saving Solution, and Motion Lighting If these are already off, check if Contrast Enhancer is enabled, which can also cause brightness to shift depending on scene changes: Settings > All Settings > Picture > Expert Settings > Contrast Enhancer Samsung’s newer TVs also include AI-powered features designed to adapt picture settings automatically. While many viewers enjoy this enhancement, others prefer more manual control. To adjust these features, go to: Settings > All Settings > Advanced Features > AI Mode Settings To ensure optimal performance, please also confirm your TV is running the latest firmware: Settings > Support > Software Update > Update Now We hope these steps help stabilize your screen brightness. If you continue to experience issues, please don’t hesitate to contact Samsung Customer Support at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun) or visit the Support link on our website.
