Thank you for your feedback. Please ensure your U8000 TV is running the latest firmware update 1132.0. To do so, go to Settings> Support> Software Update. If that version is not available you can download the update on a USB drive and manually update your TV:

Defective item, poor communication, and zero effor
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I bought this item for myself as a birthday purchase over Thanksgiving weekend. Unfortunately, it arrived defective, so I physically hauled it back to the store expecting a straightforward exchange. Instead, I was told a replacement would need to be shipped and would take nearly three weeks, with no in-store solution offered. After that, there was no communication at all. I received no updates, no notifications, nothing. When I finally followed up on December 21st, I was then told the item was out of stock due to limited availability and wouldn’t arrive until January. This was the first time I heard that — only because I reached out. No one contacted me proactively, and no attempt was made to offer any kind of remediation or alternative. At that point, there was literally no help provided, so I canceled the order altogether and purchased the item from a competitor instead. A defective product is one thing. The lack of communication, accountability, and basic customer service is another. I won’t be making this mistake again.

Picture quality is not all that great
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.We had a 60" Samsung probably 10 years old with a better brighter picture then this 70". I have messed around with all settings & adjustments trying to make the picture clearer. Some shows are greenish pale, but then reds and greens are super bright. I am not sure if I will keep or return ???

Posted .Hi StevenV,
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.
