Hi John, 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 1-800-SAMSUNG, (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun).

Hi Nita90, Thank you for your feedback. Please note that the U79000FD TV offers built-in speakers. If you're not hearing sound or if the sound cuts out and you're using only the TV’s built-in speakers (no soundbar or external device), try the following steps: 1. Check volume and mute settings, and make sure the Sound Output is set to TV Speaker: Settings > All Settings > Sound > Sound Output > TV Speaker 2. Run a Sound Test to help diagnose the issue: Settings > Support > Device Care > Self Diagnosis > Sound Test 3. Cold boot your TV by holding the power button on the remote until the TV turns off and back on (Or unplug the TV from power for 30 seconds, then plug it back in) 4. Reset sound settings to default: Settings > All Settings > Sound > Expert Settings > Reset Sound 5. Update your TV’s software in case a firmware issue is affecting audio: Settings > Support > Software Update > Update Now If none of these steps restore your sound, please contact us for further assistance. You can reach Samsung Support at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun). LiveChat is also available via the ‘Support’ link on our website. ~ Samsung Advisor
