GiovanniM,

Thank you for sharing your feedback with us. To help you get the most from your TV, you can download the full e-Manual and more by visiting Samsung’s website, then navigating to: Support > Manual & Software > TVs & Home Theater. From there, you can search for and select your U7900F TV model to view or download the available guides.

The e-Manual & User Guide are also conveniently built into your TV: Settings > Support > Tips and User Guides.

Your TV includes Learn Menu Screen, an accessibility feature that provides audio guidance for on-screen menus. When enabled, your TV will announce the name and function of each menu item as you scroll, without making any changes. This feature is particularly helpful for users who are visually impaired or new to Smart TV menus. To enable, go to: Settings > All Settings > General & Privacy > Accessibility > Learn Menu Screen. To exit, press the Return key twice.

If you’d like more assistance with this feature, please reach Samsung Support at 1-800-SAMSUNG, available 8AM – 12AM EST, 7 days a week. LiveChat agents are also available through the ‘Support’ link on our website.

Hi JeffT,

Thank you for your feedback regarding the screen abnormalities you’re seeing on your Samsung U7900 TV. First, let's ensure you are running the latest Firmware. Go to Settings> Support> Software Update.

Next, to determine whether the issue is related to the TV itself, we recommend running a Picture Test, which displays a high-definition test image for you to examine. Go to: Settings > Support > Device Care > Self Diagnosis > Picture Test.

If it appears the line has to do with the TV and not any connected devices, we recommend resetting your TV. Go to Settings > Support > Device Care > Self Diagnosis > Reset Smart Hub.

If you still have issues, please call us to set up an appointment for warranty service. Please call us at 1-800-SAMSUNG, available daily from 8AM - 12AM EST. You can also chat with a LiveChat agent by clicking the ‘Support’ link on our website.

Hi ElizabethC,

We’re sorry to hear that the picture on your Samsung U7900 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.

If your remote is having issues, we recommend that you change out the batteries and make sure the line of sight to the IR sensor located under the Samsung logo is clear.

We hope these tips help improve your viewing experience. If you need further assistance with setup or adjustments, feel free to contact Samsung Customer Support at 1-800-SAMSUNG, available daily from 8AM - 12AM EST. You can also visit the Samsung website and click on ‘Support’ for:

Hi GP64,

Thank you for your feedback on the Samsung U7900 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 – 12AM EST, 7 days a week. LiveChat is also available via the ‘Support’ link on our website.
