great tv
||Posted . Owned for 8 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.After 8 months of use, it has a spectacular image. I was hesitant about the different OLED technologies because some of them are costly, but this TV matched my budget and did not disappoint me. It needed some service, but it was fast, easy, and responsive.

Great at first, astounding after settings tweaked
||Posted . Owned for 3 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Great tv plug n play, but extraordinary if you make sure all your peripherals/components are putting out 120hz video. Absolutely astounding once you get them all synced up at 120hz 4K. Love the GUI and remote.

Stellar picture
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The colors are amazing. I put it in a pretty well lighted room with three five foot windows on the same wall as the TV. Brightness is not an issue at all. If you have windows on an angle to the TV there would be issues. In a dark room the dynamic picture mode is just too much for my brain. Sooo much depth of colors! I leave it in standard picture mode. The quantum dot TV’s are very good, but the OLED is next level for color depth and blackest of blacks.

S90D 77" is Amazing but...
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Amazing OLED with the brightest panel and magnificent colors, better than the LG C4! However, it does not upscale old content well. If you don’t intend on watching low res content, get this Samsung OLED!!

New Samsung TV
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.We decided to upgrade from a 65” tv to a 77” Samsung. We already have 2 Samsung tvs and love both for pictures, etc., on our 55” and 65”. However when we read reviews on the new 77” we bought (made 2024) we saw the newer model for 2025 was reviewed as much better for reliability. The older model froze or just quit working all together. We didn’t want to encounter such a problem so are returning the older model for a much more reliable model year at only a slight price increase. Love Best Buy for return policy as a BB member! They never disappoint.

Best Buy win
||Posted . Owned for 6 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Incredible picture. The features are great and it easily syncs itself to sound system. The purchasing experience was like only Best Buy can do in store. The closest experience would be Crutchfield but they couldn’t compete on the features benefits and advantages of purchasing at Best Buy this time.

Was great while it lasted, but now it's dead
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Was great while it lasted. Died 8 days after warranty expired. Power board fried, same as many many others. $379 for a new board I have to install myself. You'd better get the extended warranty if you buy one, or just save yourself the hassle and get something else.

Just make sure the size you get you are getting a qd-oled panel, 65" & 77" are for sure qd-oled panels the 83" version woled and youll be disappointed. Absolutely love this tv not a fan of tizen os however.

AWFUL Video Slurring While Watching Live Sports
||Posted . Owned for 2 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.BUYER BEWARE!! The 77" S90D has absolutely stunning picture quality in SDR/HDR and the QD panel is a thing of colorful beauty. However, I noticed while watching sports through DirecTV and various streaming services that the S90D seemed to have issues processing fast motion video of varying frame rate speeds. When the camera would zoom in on the players on the bench or show a slow motion instant replay, the S90D would try to adjust the frame rate by speeding it up or slowing it down, causing a 1-2 second video mess. This caused critical plays to be missed and just an awful viewing experience. Over my 60 day Best Buy trial, I became more an more annoyed. I thought that the video content was the issue, so I scanned the AVS Forum for help. I tried all kinds of setting changes but in the end I found out that it wasn't the content problem, it's most likely a hardware deficiency of the Samsung... Other users note that Samsung has had this problem for many years. This is unacceptable for a $2500 TV. The S95D is plagued with the same issue. This explains why there are always so many "Used" Samsung TV's through Best Buy. I ended up returning the S90D and exchanging it for an LG G4 which finally and thankfully eliminated all of the video problems!! I'm so happy I upgraded! If you are a SDR sports watcher (DirecTV, cable box, etc), the S90D and S95D are NOT for you. Your sports will be ruined with this TV. If you are a gamer or only watch HDR content, you probably have no problems though. It's too bad that there were so many video issues, because the picture was stunning.

Posted .Codeman00,
Thank you for sharing your thoughts on your TV’s image quality. The TV will upscale as best as possible any content sent to it. The closer your content is to 4K, the better the image will look on the screen.
Here are some tips to help improve the picture clarity:
1) HDMI cables are recommended for optimal HD viewing.
2) If you have an analog cable box or satellite box, upgrade to a digital cable box or satellite box.
3) Change the output resolution of your devices, such as digital broadcast receiver, IPTV, and set-top box to UHD or HD.
4) You can further adjust your sharpness, brightness, contrast, color, and more by going to Menu > Settings > All Settings > Picture > Expert Settings
5) Choose a Picture Mode by going to Menu > Settings > All Settings > Picture > Picture Mode and choose from Dynamic, Movie, or Filmmaker Mode.

Best buy true is the best place to buy.
||Posted . Owned for 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The first TV I got died after 5 days, so I contacted Best buy customer service and they had the geek squad come out and bring me a brand new one and remove the defective one for no charge. I couldn't be more happy with Best buy customer service and they have got a customer for life now. Thank you Angel and Matt from the geek squad. The TV the second to none in picture quality and I have it paired with a Samsung home theater setup.

Stopped working one month after warranty expired.
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.TV looked great and working well. One month after warranty expired, it would not come on. Now payimg for expensive repairs. I looked at reviews, and apparantly this is a major problem for this TV. I went ahead a purchased an LG, which seems to be a much better product and a much better picture. I'll fix the Samsung just because i dont want to trash it. I may try and sell it after its fixed.
