Remarkable TV

Quality5 out of 5Value4 out of 5Ease of Use5 out of 5I bought a 65 inch OLED previously and had to move it to the main room after the old 13 year old TV died. I decided to go a little bigger since I use this in the basement. It serves as the main TV for me as well as my kids for video games. I had the other OLED for 3 years and have no burn in with lots of Fortnite and other games. I decided to go with OLED again and with it going on sale this helped tremendously in making this decision. Highly recommended

LG OLED = The Best Picture
Posted .Features
Quality5 out of 5Value4 out of 5Ease of Use5 out of 5This our 4th OLED. Once you get used to OLED it is hard to watch anything else because there is nothing else that looks as amazing. We wanted to upgrade our 65in OLED in our main room to a larger size. The 77in OLED was a bit pricey so we shopped around for larger TVs (75in - 85in range) that were not OLED but a little cheaper. After comparing many, we realized we just couldn’t lose the picture quality we are used to for a larger screen. A few months later we just decided we had to do it so we purchased the LG OLED 77in from Best Buy and had it delivered to our door! What can I say other than it was well worth it! The 77” OLED is amazing and has a wow factor with Movies and for Gaming. As you would expect, the picture and details are unmatched with the signature contrast and black levels that you can only get from OLED. The colors are deep and rich and are more than impressive and able to retain the smallest of details in an image without color bleed. The eARC supports full ATMOS, which is important to be able to stream ATMOS content from the TV and run it through an Atmos receiver. The OLED has a fast, slick UI and great magic remote. The viewing angle is perfect from anywhere and the TV is super thin and looks great hanging on the wall. Friends and family that watch the TV that usually doesn’t notice or care about the picture even comment on how amazing the picture is. If you love the amazing picture quality, love to game, want the best audio for your Atmos system, and If you are thinking about this TV - just go for it.

Quality5 out of 5Value5 out of 5Ease of Use5 out of 5Pros mentioned:Design, Picture, Sound qualityI talked my fiance out of the sony 85 inch 950 to get the 77inch LG c9 and she even agreed it was the best choice. I usually don't win many of those arguments but I'm glad I won this one. Picture quality is amazing and looks great above my fireplace. Sound is good but I can't wait to hook it up to my sonos sound system that's on the way. If you want an oled go with LG. Scored a great deal on labor day and saved 1800.

Quality5 out of 5Value5 out of 5Ease of Use5 out of 5Pros mentioned:Design, Picture, PriceAmazing TV, absolutely incredible picture and just beautiful to look at. 4k, Dolby Vision, HDR10, HD all look phenomenal on this TV. I got this as an open box item for $2,299 but the tv was still in the box with all the plastic on it. Just cant beat that price for a TV this good. My highest recommendation.

Price is Ridiculous... but it's worth it!

Quality5 out of 5Value4 out of 5Ease of Use5 out of 5Pros mentioned:Picture, PriceAfter doing so much research I finally went for the LG - 77" Class - OLED - C9 Series. The price is definitely on the high side but if you have the money and not worried about spending that extra cash then you'll like this TV for sure. The overall picture quality and performance is excellent! Just make sure to buy extra warranty from Best Buy otherwise if anything goes wrong... you're on your own. I also bought the Best Buy installation package. The Geek Squad team; Rafa M. and Clara Q delivered the TV to my house and mounted it on the wall. Their work was excellent! They kept the working area clean and tidy. They also helped me carry the empty box downstairs to my garage. They really went above and beyond and I'm very happy to recommend them.

Quality5 out of 5Value4 out of 5Ease of Use5 out of 5Pros mentioned:Design, PictureBought this tv about 1 1/2 months ago and let me tell you this 77 C9 has the most vivid screen I have ever seen. The HDR is amazing and 4K content and games are just pop out of the screen beautiful. I have not been paid or promoted to make this review I am a homeowner that loves TEC and only buys the best in its class. If you want the best of the best and are in the market for a tv look at the C9 series of lg’s lineup of OLED TVs you can’t go wrong.
