Posted .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.

Samsung TV
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Great Tv, excellent price. Best Buy is the place to go!
I would recommend this to a friendVery limited connectivity
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Picture seems good, but lack of connectivity is my reason for lower rating. There are zero Optical outputs, and only two HDMI, one of which is eARC, so if you have a soundbar, that really only leaves you one input. I found this to be ridiculous. My laptop has more connectivity than this TV. If there were two more HDMI I would rate it a 5.

Basic TV For The Price
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Purchased as a moderately priced second tv. Tizen interface works OK, but I believe the Roku interface is better. Picture quality is ok; I expected a little better than what this tv offers, even after making a few adjustments in settings. Recommend at a price point that purchaser would be comfortable with (i.e, Sale)

Not happy with this TV
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.We found setting this TV up to be extremely difficult. Also, this TV did not have a place to plug in our external Bose speaker. While changing the settings the screen seem to have a defect when we got strange horizontal lines moving on the screen. At that point we returned the product. So, I really can not speak to any other attributes.

Posted .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.
