Great truly smart t.v.

[This review was collected as part of a promotion.] This is a fantastic t.v. The operating system is so smooth & intuitive. The transition form app to app is seamless. And it connects to our Samsung phones very quickly & easily. The picture is clear & the refresh frame rate is quite high to give high definition visuals. Definitely recommend.

Great clearity, resolutions and much more

[This review was collected as part of a promotion.] Son happy with our crystal 4k uhd smart tv! It almost feels as if your also in the picture of what we are watching it feels so realistic especially with out samsung surround sound to go with! Never been so satisfied and ecstatic when we're actually watching a movie with the family like i am now! Only concern is how intense and level of of access people have at their finger tips to hacking accessories makes me want better security systems

Good quality for the price range.

[This review was collected as part of a promotion.] The picture quality is pretty good and bright. It's not the sharpest, but for a budget LED tv it is good enough. Color reproduction is good. Only thing missing is sound quality. The dialogues are sometimes not very clear when there are some background noises.

Great Picture and Sound

[This review was collected as part of a promotion.] Finally got my large 55” 4k HDTV I always wanted. Beautiful picture, great sound without any external speakers. However navigating the Home Screen took a little time to figure out. But extremely happy.

Stunning tv with 1 caveat

[This review was collected as part of a promotion.] This television is beautiful in its clarity, color, resolution, brightness, & contrast. Everything about it is gorgeous. My only qualm is that it doesn't ever display the time. It's very odd. Otherwise, it would be a 5/5, but it's currently a 4/5 for me.

Great features and a great product!

[This review was collected as part of a promotion.] This TV offers great features for the price. The screen has decent levels of color and good motion smoothing. I have not had artifacts within my viewing material. The Tizon OSis peppy, it handles the apps I have on the TV. Netflix, Amazon Prime and Paramount + work without issues. The resolution supports what most users will need. Programs pop in HD and 4K when avalable. I like the Knox security features. I feel a bit safer with Knox and how it vets apps and provides a safer environment The TV itself is light weight and thin,making it easy to either put on a stand or mount it to a wall.

Improper voice/lip synchronizing.

[This review was collected as part of a promotion.] This TV has the worst picture/voice match I have ever seen. On some channels and most streaming the voice matches the picture, but most cable channels the voice is 1 or 2 seconds after the picture. It is not synchronized with the lip movement at all. I have tried correcting this in the setting several times, but it has not worked.

Hi Ironhorserider, Thank you for your feedback. You mentioned already adjusting settings, but I am going to put a few suggestions below, just in case you have not tried these. 1. Adjust Digital Audio Delay. You can manually increase the audio delay to better match the video: Settings > All Settings > Sound > Expert Settings > Digital Output Audio Delay 2. Enable Audio Pass-Through. Samsung TVs include an audio pass-through option, which sends the audio signal directly to your connected soundbar or receiver without additional processing by the TV. This can reduce delay when using external audio devices: Settings > All Settings > Sound > Expert Settings > Digital Audio Output Format > Pass-Through 3. Check for Firmware Updates. Ensure your TV is running the latest software, which may include performance improvements related to sound or sync: Home > left directional key > Settings > Support > Software Update > Update Now If the issue continues after these steps, please contact Samsung Support for additional troubleshooting or assistance. We’re here to help at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun). LiveChat and additional support resources are also available through the Support link on our website. ~Samsung Advisor

Terrible for streaming

We purchased this TV on a Black Friday deal and have regretted it ever since. If you are looking for a TV for streaming, this isn't the one. If the people in the show are doing any more than just sitting there, the picture gets very pixelated. I've contact samsung for help and was told the show was just old. However, it happens on even shows that are just released. So frustrating for what uses to be a great brand name.

Hi SamanthaF, 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. There are also several settings you can adjust to improve motion clarity. Go to: Home > left directional key > Settings > All Settings > Picture > Expert Settings, and review these key settings: Picture Clarity Settings • Off: Disables all motion enhancement • Auto: Automatically adjusts motion clarity based on content • Custom: Enables manual control of: o Judder Reduction: Smooths motion in film-based content o LED Clear Motion: Increases sharpness during fast movement o Noise Reduction: Helps reduce distortion in lower-quality sources We hope these settings help improve your viewing experience, especially with fast-moving content. If you'd like further assistance, feel free to reach out to Samsung Support at 1-800-SAMSUNG, 8AM – 12AM EST, 7 days a week. LiveChat is also available via the ‘Support’ link on our website. ~ Samsung Advisor
