Spend more, buy better

[This review was collected as part of a promotion.] One of the first things you notice once you get the TV setup is the remote. The lack of number buttons and no microphone. This makes it a hassle to change channels. When you use the channel up/down button it takes you to the Samsung plus app even when you're watching antenna TV. Syncing the audio to the video is impossible for any length of time. When you get it synced for one channel, it's off on other channels. The two ten watt speakers are extremely under powered. You have to have the TV volume at half or better to hear most channels, and it won't go high enough to hear others. Samsung plus has a nasty habit of locking up, freezing, for several seconds at a time and usually in the most inopertune moments. This means you miss important scenes or happenings in the program you're watching. No microphone! The remote would be easier to tolerate if you could at least command the TV by voice. The menu seems clunky and not very well laid out or labeled. Pluses include that the TV starts quickly and has vibrant color.

Hi Unhappy viewer, We appreciate your feedback and have a few recommendations. First, please know that 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 Finally, Samsung remotes are designed to offer convenient control, but we understand if you’d prefer to use a universal remote. If you have any questions or need help, please do not hesitate to reach out to us at 1-800-SAMSUNG, available daily from 8AM - 12AM EST. You can also visit the Samsung website and click on ‘Support’ for: • Live Chat • Manuals, Software, & Warranty Info ~ Samsung Advisor

3 out of 5 stars review

Great price, disappointing viewing

[This review was collected as part of a promotion.] It’s a large screen TV at a great price. My primary quarrel is with watching dark shows (so many are these days) during the daytime in a well lit room. It proves nearly impossible to see any detail. It’s unfortunate and what that means is I can only watch my primary shows during the evening. TV is a serious hobby and I go to sleep fairly early so it’s upsetting to be confined to evenings only which provides only 1-2 of quality watch time. Unfortunately there is not enough adjustment within the TV’s picture capabilities to combat this though I’ve optimized settings as much as possible. I also had an issue with weird red lines appearing onscreen occasionally. I had to unplug the TV to make them go away. This issue seems to have resolved after 3-4 months.

Hi Bought the tshirt, 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. I hope these suggestions help. If you have any other questions, feel free to call us at 1-800-SAMSUNG between 8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun, any day of the week. You can also reach our LiveChat team by selecting the ‘Support’ link on our website. ~ Samsung Advisor

Great t.v.

[This review was collected as part of a promotion.] This is a fantastic t.v. The user interface is very smooth & responsive. No glitches or lagging. The picture is colorful & vibrant without eye strain. The sound is quite clear & full enough to hear from another room. The integration with a Samsung phone or sound bar is seamless. The price is also a plus.

Amazing family addition!

[This review was collected as part of a promotion.] Clear picture quality, no unwanted dimness, the resolution is great especially playing video games on HDR. It's thin black bezel let's it fit perfectly into our living room decor. The colors are deep and vibrant when watching content or playing video games allowing for perfect entertainment sessions. The apps that are available are great and can be password protected to keep children from engaging unwanted content. Overall a 10/10 television that delivers.

Great feature

[This review was collected as part of a promotion.] I’ve had a great experience with the 65" Crystal UHD U7900F. The 4K picture quality is sharp, bright, and very vibrant, making everything from movies to everyday shows look great. The smart features are easy to use and responsive, which makes navigating apps simple. I’ve always been a big advocate for Samsung products. If I could afford to have all of them, I would. They consistently deliver quality, and this TV is no exception

Highly recommended!

[This review was collected as part of a promotion.] I'm really a fan of Samsung whether it be a mobile device or a tv so this one is really a perfect choice for me and my family. Everything you're looking for a tv is already covered by Samsung. The brigtness, color and security passed the requirement that I want in a tv.

Amazing

[This review was collected as part of a promotion.] Picture quality is amazing compared to my previous Hi sense 55", movies are even better to watch with bright colors and black background. Also using Dex with my Z Fold 6 makes it easier with Wireless. If you have kids the security makes it easy to limit them. I don't regret this product.

Just what the Doctor ordered

[This review was collected as part of a promotion.] The TV is surprisingly light for its size. It was easy to hang and fit our space perfectly. Its brightness, resolution, and features were exactly what we wanted and needed. So glad we bought a Samsung, excellent choice, and we as a family love how well it plays movies, tv, and the sound for oem speakers is excellent and clear. We love the security of the online features. Overall, the vibrant picture is what we love the most. Thank you Samsung for a great TV.
