Hi Jselover, We’re sorry to hear that the picture on your Samsung U7900F TV appears too dark. If this isn’t meeting your expectations, there are several settings you can adjust to improve the overall brightness and clarity of your screen. First, try disabling certain energy-saving features that may be dimming the screen automatically. Go to: Settings > All Settings > General & Privacy > Power and Energy Saving, then turn off Brightness Optimization, Energy Saving Solution, Motion Lighting, and/or Contrast Enhancer. Next, adjust the Picture Mode to better match your viewing environment: Settings > All Settings > Picture > Picture Mode and choose from the following: • Dynamic – Brighter and clearer for well-lit rooms • Standard – Balanced for most environments • Movie – Ideal for watching in a dark room • Eco – Designed for energy savings • Filmmaker Mode – Preserves the creator’s original intent You can also manually adjust brightness by going to: Settings > All Settings > Picture > Expert Settings > Brightness. Use the slider to set a level that suits your preferences (0–50). Finally, we recommend making sure your TV has the latest software installed: Settings > Support > Software Update > Update Now We hope these tips help improve your viewing experience.
