    Great picture - once again!

    My wife suggested we get a bigger TV than the current LG - 55" Class C1 Series OLED 4K UHD Smart webOS TV (2021) we were currently watching. We enjoyed this TV and the picture, so we decided to stay with another LG OLED and went with this 77" model. The picture continues to be outstanding, but one of things we noticed was the improvement of speed within the LG OS. Apps respond faster and load faster - Netflix, YouTube TV, Amazon Video, Apple TV, MLB app, and Paramount + all seen to load faster. Just the overall speed has improved - I'm sure there's been improvements in 5 years of technology. Another reason for choosing this TV was because of the base. The depth of the base was only 10.5 inches, which allowed us to place the TV on the fireplace mantle and not hang off the mantle. Most TV's have the support legs on the ends and their depth is 14-15 inches which wouldn't work for us, plus the base is very solid and stable - we experience no wobble or unstableness . We've only had up and running for three days, but really enjoying the TV so far. Overall, a VERY solid performer with excellent picture quality. Truly enjoyed watching my favorite sports teams on this 77" TV....color of the grass and uniforms stands out as it shows a true representation of the color accuracy...everyone knows what green grass looks like and the colors of their favorite sports teams. As always, I worry about longevity and failing out of warranty vs. the cost of the set. Overall, we've had good luck with LG in this department with other TV's and appliances, so I hope this trend continues. This is the biggest TV we've ever owned, but so far, it is exceeding expectations.

    No longer need to go to the movie theater!

    This tv is GORGEOUS. When we were shopping for a new OLED tv, this one by far stood out among all the others. Though the price was a bit hefty, we got it on a special for the 60th anniversary. HIGHLY RECOMMEND THIS TV. Picture is absolutely beautiful. I have no regrets on this purchase. The remote has a feature to be used like a Wii remote, which I personally don't care for but it's something you can turn off. Other than that, I don't have any issues with this tv. It connected to my Alexa so I can remotely control it. Anyway, highly recommend this tv, I wouldn't think too hard on the price because you're definitely getting your moneys worth. Tv is massive, the box is a little bit bigger than the tv (obviously) Like I said, no longer need to go to the theater because we have a movie screen at home now.

    Almost Amazing

    Picture quality is awesome. Black are beautiful. Brightness is almost blinding in my small dark room which could be considered a good or bad thing. But the os… is actually terrible. The OS on this tv runs slower than my tv from 2010. If you turn the tv on too quick and don’t give it time to connect to WiFi some of the applications won’t even open. Mind you the router is directly next to my tv. There’s even buffering during some playback at time like come on we’re in the big 2026. Tv is beautiful but be ready to buy an Apple TV if you want it to run properly.

    Epic TV Choice!

    After researching reviews and then spending quality time with Josiah in Pleasant Hill, we made the choice to go from Sony to LG and we love it! Picture quality is phenomenal, colors are vivid and its ease of use is even better. We’re not exactly tech savvy but this TV is truly easy to operate. Bought an LG sound bar as well. LG has the Oled technology well dialed in. This was the best decision ever!

    Awesome Television

    I bought this for my living room PC setup. Great colors, great contrast, handles my 5070 TI on high settings. Movies look great and does well in a bright room.
