Hi Atapap, Thank you for your feedback. We’re sorry to hear you’re not fully satisfied with the picture quality on your Samsung U7900F TV. If the image appears too dark, we suggest disabling certain energy-saving features, which can automatically adjust brightness and affect how the screen looks. 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. You can also adjust the Picture Mode to better suit your environment: Settings > All Settings > Picture > Picture Mode • Standard – Default mode for general viewing • Dynamic – Brighter and clearer, ideal for well-lit rooms • Movie – Best for dark room viewing • Eco – Energy-saving mode • Filmmaker Mode – Preserves content as intended by creators To fine-tune brightness, go to: Home > left directional key > Settings > All Settings > Picture > Expert Settings, then adjust the Brightness level (0–50) to your preference. Lastly, please make sure your TV is running the latest firmware: Home > Home > left directional key > Settings > Support > Software Update > Update Now We hope these tips help improve your viewing experience. If you need further support, feel free to contact us at 1-800-SAMSUNG, 8AM – 12AM EST, 7 days a week. LiveChat is also available via the ‘Support’ link on our website. ~ Samsung Advisor

Hi Teachit, We appreciate your feedback and are glad you reached out to us. There are a few adjustments you can make that may improve your experience. First, let's ensure you are running the latest Firmware. Go to Settings> Support> Software Update. If the picture appears unclear, dull, or lacks definition, there are several settings you can adjust to improve clarity and overall image quality. Go to: Settings > All Settings > Picture > Expert Settings, and review these key settings: Picture Clarity Settings: While originally intended for motion handling, these can also impact overall clarity • Off: Disables motion enhancements • Auto: Automatically adjusts based on content • Custom: Lets you fine-tune: o Judder Reduction – Helps smooth out uneven motion o LED Clear Motion – Boosts sharpness in fast-moving content o Noise Reduction – Reduces distortion and enhances detail in lower-resolution sources Core Picture Settings • Brightness – Controls overall screen brightness • Contrast – Enhances the difference between bright and dark areas • Sharpness – Adjusts edge definition; closer to 20 increases detail • Color – Enhances depth and intensity of colors Finally, while your TV may currently default to Samsung TV Plus when powered on, you can customize what your TV does at startup by adjusting the Start Screen Options. To do this, navigate to: Settings > All Settings > Advanced Features > Start Screen Option and choose from the following: 1. Start with Smart Hub Home – Automatically launches Smart Hub when the TV is turned on. You can enable or disable this option based on your preference. 2. Autorun Multi View Casting – If you cast YouTube content from your mobile device, the TV will automatically display the content using Multi View. 3. Autorun Multi View Mirroring – When you screen mirror your mobile device, Multi View will automatically open to show your device’s screen.
