Hi Noah,

Thank you for your review. While your U7900F 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.

If you need help adjusting these settings or have any other questions, please contact Samsung Support at 1-800-SAMSUNG, 8AM – 12AM EST, 7 days a week. LiveChat agents are also available by clicking on the ‘Support’ link on our website.

Hi user503440,

Thank you for sharing your experience with volume fluctuations on your Samsung U7900F TV. Sudden changes in volume can often be related to audio settings or content differences between sources or apps.

Please try the following adjustments to help stabilize your TV's audio:
1. Enable Auto Volume. Go to: Settings > All Settings > Sound > Expert Settings > Auto Volume. This feature helps maintain a consistent volume level when switching channels or apps.
2. Change Sound Mode. Try a different sound mode to see if one offers a more stable output: Settings > All Settings > Sound > Sound Mode (We recommend Standard or Amplify for more even performance.)
3. Check External Devices. If you're using a soundbar, receiver, or other audio device, check that its volume leveling or dynamic range settings aren’t interfering with the TV’s audio.
4. Update Firmware. Ensure your TV is running the latest software, as updates may include audio improvements: Settings > Support > Software Update > Update Now

If the issue persists after these steps, please don’t hesitate to reach Samsung Customer 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.

Hi CarlB,

We’re sorry to hear you’re not fully satisfied with the picture quality on your Samsung U7900 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.

Hi Keelo22,

We appreciate you sharing details about the flickering you’ve noticed on your Samsung U7900 TV. This behavior may be related to energy-saving features or dynamic picture settings that adjust the screen brightness automatically.

Please try disabling the following features: Settings > All Settings > General & Privacy > Power and Energy Saving
• Brightness Optimization
• Energy Saving Solution
• Motion Lighting

If these are already off, check if Contrast Enhancer is enabled, which can also cause brightness to shift depending on content: Settings > All Settings > Picture > Expert Settings > Contrast Enhancer

To ensure optimal performance, please also confirm your TV is running the latest firmware: Settings > Support > Software Update > Update Now

We hope these steps help stabilize your screen brightness. If you continue to experience issues, please don’t hesitate to contact Samsung Customer Support at 1-800-SAMSUNG, 8AM – 12AM EST, 7 days a week. LiveChat is also available via the ‘Support’ link on our website.
