Samsung - 77” Class S90F Series OLED 4K
||Posted . Owned for 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The picture quality is stunning; vivid colors and deep blacks really stand out. That said, the viewing experience depends heavily on the production quality of the content you’re watching. High-end shows look amazing, but lower-quality broadcasts can appear average. Also, while the screen is decent in normal lighting, the anti-glare performance could use improvement, especially in brighter rooms. Overall, solid OLED performance with a few trade-offs.

Posted .Hi Bill,
Thank you for sharing your thoughts on your Samsung S90F TV’s image quality. Your TV is designed to upscale content to the best possible quality based on the resolution of the source. In general, the closer your content is to native 4K, the sharper and more detailed it will appear on screen.
Here are some tips to help improve picture clarity and overall upscaling performance:
1. Use HDMI cables for the best high-definition signal.
2. If you’re using an analog cable or satellite box, consider upgrading to a digital box for better signal quality.
3. Change the output resolution of connected devices (like a cable box, streaming device, or IPTV box) to UHD or HD, if supported.
4. Go to Settings > All Settings > Picture > Expert Settings to fine-tune options like Sharpness, Brightness, Contrast, and Color.
5. Select a Picture Mode that fits your environment: Settings > All Settings > Picture > Picture Mode – try Dynamic, Movie, or Filmmaker Mode.
6. Explore Picture Clarity Settings under Expert Settings for added detail enhancement. Use Auto or Custom to adjust Judder Reduction, LED Clear Motion, and Noise Reduction.
7. Enable AI Mode, which automatically analyzes the content and your environment to deliver optimized picture and sound. Go to: Settings > All Settings > Advanced Features > AI Mode Settings
8. Ensure your TV is running the latest firmware to benefit from performance improvements and the latest enhancements: Settings > Support > Software Update > Update Now
If you’d like personalized help fine-tuning these settings, please reach out to Samsung Support at 1-800-SAMSUNG, available from 8AM - 12AM EST, seven days a week. You can also chat with one of our agents by clicking the ‘Support’ link on our website for:

I would recommend this to a friendBars of Death
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.After two weeks of owning this tv I already saw defects within the tv. There were many bars that would stay discolored on the tv. I would have to cycle the tv to get rid of them but other than that scary mishap it seems to be a fairly good tv. This is my first oled but after that incident I’m staying away from Samsung. It’s back to TCL and Sony for me. If I spend over $2k on a tv I better not have these kinds of issues.

Great TV..but still no Dolby Vision
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Great TV, but that matt screen was not to my liking. But the BIG downsize is the fact that Samsung is still not offering Dolby Vision. That makes no sense. I returned the TV and opted for the LG C5 instead.

I would recommend this to a friendDon't buy! Don't believe me. Do your research!
||Posted . Owned for less than 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.TV is junk. Had it for a week before it started to show issues. First a 5 inch line from top to bottom started. Then the picture would go out. Sound would work but no picture. You could turn off the power and turn it back on and it would work for about 5 minutes and then go off again. Looked online and found this to be a common issue with this model. Don't buy! Best Buy was great in solving the issue. Went with an LG instead, couldn't be happier.

We appreciate you sharing details on your Samsung S90F TV. This behavior may be related to energy-saving features, AI-powered optimizations, or dynamic picture settings that automatically adjust screen brightness based on content and viewing environment.
Please try disabling the following features: Settings > All Settings > General & Privacy > Power and Energy Saving > Brightness Optimization, Energy Saving Solution, and Motion Lighting
If these are already off, check if Contrast Enhancer is enabled, which can also cause brightness to shift depending on scene changes: Settings > All Settings > Picture > Expert Settings > Contrast Enhancer
Samsung’s newer TVs also include AI-powered features designed to adapt picture settings automatically. While many viewers enjoy this enhancement, others prefer more manual control. To adjust these features, go to: Settings > All Settings > Advanced Features > AI Mode Settings
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.

Goodbye to Best Buy
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.This TV is 5-Stars however the Price Match policy is misleading. Customer Service does not care about keeping their long term purchasers happy. After years of buying all of my electronics products at Best Buy I will be going elsewhere in the future.

My Samsung 77
Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.It’s bigger than the one I had which was 65. It fills the wall a lot better. The color is much better than the older one much brighter and I love how it looks and the sound is excellent.

S90f HUGE improvement over the s90c and c4
Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I had some minor issues with my s90c …. SDR had a problem with flickering in near dark complex scenes and motion was always a little off … the s90f processor is so much better and just feels stronger it handles motion like a champ and all flickering is gone … now to the main event the brightness …. I own the s90c and c4 and this blows them both out of the water … I also owned a g4 for a short period of time but had some issues with it and I feel the s90f rivals the g4 brightness …. I have not seen the c5 yet but h have a feeling the s90f is going to absolutely destroy it …. I am very balanced if anything you could say I’m more or an LG fan because at first I wouldn’t go to Samsung because of no Dolby vision … but once you QD-OLED it’s hard to go back … my c4 is an 83 inch which QD-OLED does not offer that size ….if you are on the fence about the c5 vs s90f it is a no brainer definitely go with the s90f
