So slow
||Posted . Owned for 4 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I bought this TV earlier in the year and ever since I bought it it's been super slow, there's no app store and you can't customize it. Plus the interface is ugly.

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)

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.

TRASH!!!!
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Horrible tv! Stopped working after only 1 month. Tried factory resets, got it working for 1 day, then couldn’t get it to respond at all, blank screen. Called Samsung and even did a video call so they could see issues. They said they’ve would have to send a technician to replace some sort of power source. I said on a new TV? They said unfortunately they are having problems and it is not that unusual. I said it would be easier for me to buy a different brand TV and never trust a Samsung product again

Posted .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.

• 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.

Not worth the money
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.The picture quality on this TV is extremely disappointing, especially in dark scenes. Even with brightness turned all the way up and trying multiple picture modes, it’s very hard to see what’s going on. A lot of detail gets lost, which makes watching movies and shows frustrating. I expected much better performance and wouldn’t recommend this TV if you watch a lot of darker content. I wish I would have returned it.

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.

Posted .Hi DelaynieW,
Thank you for sharing your experience. Buffering during streaming is typically related to internet speed or signal strength. This can happen when your connection isn’t able to deliver data quickly enough for smooth playback.
We recommend the following steps to help improve streaming performance:
1. Use a 5GHz Wi-Fi connection, if available
2. Try a wired LAN connection for more stability
3. Reposition your router to minimize obstacles between it and the TV
4. Make sure your TV is running the latest firmware (Settings > Support > Software Update)
5. Run Device Care to optimize performance: Home > left directional key > Settings > Support > Device Care > Start Device Care
If buffering continues, you may want to contact your internet service provider to check your current speed or explore upgrade options.

Samsung tv
||Posted . Owned for 9 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Never purchase a Samsung or apple tv, and buy the warranty , because you do not get to exchange it, they send it off , and you hear absolutely nothing about it, so a 60 dollar warranty is worthless, it was Sunday May 10th , today is Friday, and was told I would know something in 3 days. Just remember this when you purchase these 2 brands, they need to tell this upfront. The tv is 9 months old.

Posted .Hi AnthonyC,
Thank you for your feedback. Please know you can control multiple devices with your Samsung TV remote if they are connected via HDMI cable. If your Remote isn’t controlling your external device, please try the following:
1. Reset the Remote: Press and hold Return and Enter (center of the navigation pad) for more than 10 seconds. Then, re-pair the remote by pressing Return and Play/Pause simultaneously for at least 5 seconds, or until a message appears on screen confirming connection.
2. Check the Remote Battery: On your TV, go to: Home > left directional key > Settings > All Settings > General & Privacy > Remote Control
3. Ensure the Remote is Sending IR Signals: Use your smartphone camera to check for infrared. If you see a flashing light from the remote’s front when pressing a button, it’s working properly.
4. Enable Anynet+ (HDMI-CEC): This feature allows your remote to control HDMI-connected devices. To enable it:
Settings > All Settings > General & Privacy > External Device Manager > Anynet+ (HDMI-CEC) = On
5. If the device doesn’t support HDMI-CEC, use the Universal Remote feature. First, confirm the external device is properly connected. Then go to: Home > left directional key > Connected Devices > Universal Remote Setup, and follow the prompts.
If the issue persists, please call Samsung Support at 1-800-SAMSUNG, 8AM – 12AM EST, 7 days a week. Our LiveChat agents are also available by clicking the ‘Support’ link on our website.
