Terrible TV
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Never buy anything from Best Buy and never buy from Samsung. I bought a tv and it has stopped working within 2 months of me purchasing. Neither party has been willing to work with me to help me get my issue resolved. Best part was when I went to get my issue resolved I watch an employee drop a piece of equipment directly on the ground. DO NOT SHOP HERE.

Posted .Hi GloriaT,
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.

Low Quality Samsung Product

Posted .Display52,
Thank you for sharing your thoughts on the available inputs for the U7900F. If an Optical port is a crucial part of your setup needs, you’ll find that connection starting with our Q8F Series and above.
For future purchases, we recommend double-checking the product specs on Best Buy’s site to ensure the model you choose has the ports you need. You’ll find the full list under the “Specifications” tab (just beneath the Highlights section): https://www.bestbuy.com/site/samsung-43-class-q7f-series-qled-4k-uhd-samsungvision-ai-smart-tizen-tv-2025/6619443.p?skuId=6619443

Posted .Hi MichaelW,
We appreciate your feedback regarding your U7900 TV’s performance. If you're experiencing slow apps, freezing, or lag in general response time, try the following steps:
1. Check for firmware updates – Keeping your TV up to date can resolve many performance issues: Home > left directional key > Settings > Support > Software Update > Update Now
2. Run Device Care – This tool checks system memory, frees up cached data, and closes background apps that could be slowing things down: Home > left directional key > Settings > Support > Device Care > Start Device Care
3. Cold boot your TV – With the TV powered on, press and hold the Power button on your remote for 5+ seconds until the TV restarts. This helps refresh the system.
If you're still noticing performance issues after these steps, please contact Samsung Support at 1-800-SAMSUNG, 8AM – 12AM EST, 7 days a week. You can also connect with a LiveChat agent via the ‘Support’ link on our website.

Posted .Hi user520355,
Thank you for sharing your experience with buffering on your TV. The issue you’re encountering may be related to network strength or stability. We recommend the following steps:
1. Connect to a 5GHz Wi-Fi network, if available
2. Use a wired LAN connection for increased stability
3. Reposition your router to reduce obstacles between the TV and the router
Please also check that your TV is running the latest firmware by going to: Settings > Support > Software Update. From there, you can also enable Auto Update for added convenience.
For improved app performance, we recommend running Device Care, which can help by clearing memory and closing background apps. To access it: Settings > Support > Device Care
We hope these steps improve your streaming experience. If the issue continues, please reach out to 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.

Not the best
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Rating 2.2 not a lot to say..not a very loud product
No, I would not recommend this to a friendBrand response from Samsung
Posted .Hi JBsoyea,
Thank you for purchasing Samsung’s U7900F TV and for sharing your feedback regarding low volume. To start, we recommend making sure your TV is running the latest firmware, as updates can include improvements to sound performance: Home > left directional key > Settings > Support > Software Update.
If volume levels still seem too low, you can improve sound performance by adjusting a few key settings:
Sound Mode: Navigate to: Settings > All Settings > Sound > Sound Mode
Auto Volume: This feature helps maintain consistent volume levels across content and input sources. Turn it on under: Settings > All Settings > Sound > Expert Settings > Auto Volume = On
You can also explore Expert Settings to fine-tune sound output with adjustments for Balance, Equalizer, and more.
If you’re considering enhancing your setup, Samsung’s Q- and S-Series Soundbars (like the HW-xxx) feature Q-Symphony, which syncs your TV and soundbar speakers for a fuller, more immersive sound experience.
For personalized support with these settings or selecting a soundbar to complement your setup, contact Samsung Support at 1-800-SAMSUNG (8AM – 12AM EST, 7 days a week) or use LiveChat via the ‘Support’ link on our website.

Posted .Hi Minniex2,
Thank you for your feedback. Please ensure your U7900 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:
1. On Samsung's website (upper right corner), go to: Support > Manual & Software > Find your TV model, and click on the Firmware – Upgrade File.
2. When the file has finished downloading, locate it and then unzip it. There is normally one folder inside but there may be multiple files.
3. Copy or move all of the files that were included in the zip file to a USB flash drive, but do not place them inside any other folders. If you place the software folders inside a folder on the USB flash drive, the TV or monitor will not find them.
4. Connect the USB drive containing the software upgrade into a USB port on your device.
5. Using your device's remote, navigate to and select Settings, then select All Settings, and then select Support. Select Software Update, select Update Now, and then select Yes if prompted.
Your device will search the USB drive for update files. Follow the on-screen instructions to install the updated software. Updates usually take a few minutes; please do not turn off the TV until the update is complete. When the update is finished, it will restart automatically.
Should you need any help, please call us at 1-800-SAMSUNG between 8AM and 12AM EST, any day of the week. You’re also welcome to visit the Samsung website and select ‘Support’ for:
