Hi Jerry, Thank you for your feedback on the Samsung U7900F TV. 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 And don’t forget to check for the latest firmware, which may improve performance: Settings > Support > Software Update > Update Now These adjustments can make a noticeable difference in overall clarity. If you need further help tailoring the settings to your preferences or environment, please contact Samsung Support at 8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun.
