Best TV I have ever owned!
The 77 inch Sony Bravia 8 OLED is easiest the best TV I have ever owned. This tv being an OLED means you get true inky blacks. But what really stood out to me were the colors! The moment I loaded up a movie I instantly noticed how deep and rich the colors pop out at you. And I am not talking over saturated colors. Sony also has the best motion processing and upscaling in the business. This tv really helps those old blu ray disc or even DVDs look even better than you remember. What I do find a little lackluster is the lack of HDMI 2.1 ports. Yes this tv does have HDMI 2.1 ports but only 2. Other brands such as LG and Samsung offer 4 HDMI 2.1 ports. Aside from that, I highly recommend this TV. Movie nights are spectacular. Gaming on this TV has been mind blowing. 5/5 stars!

Stunning Picture and Next-Level Performance
This Sony OLED has completely transformed the way I watch movies, sports, and play games. The picture quality is outstanding — deep blacks, vibrant colors, and incredibly sharp detail even in fast-moving scenes. Dolby Vision and HDR really pop, and paired with my sound system it feels like a theater at home. Gaming on this TV is amazing too. The low input lag and 120Hz refresh rate make everything buttery smooth, and the PS5 looks unreal on it. Setup was simple, the Google TV interface is easy to navigate, and it integrates seamlessly with my smart home devices. Overall, this is hands-down one of the best investments I’ve made for home entertainment.

Sony Bravia 8 OLED 4k HDR
Great Sony OLED TV! True 4k experience. Enjoy playing PlayStation 5 & Steaming tv/ movies. The UI is smooth and snappy. The remote is good quality in addition too the quality of the TV. I’m not much of a sit on my couch and hang out in my living room all day but this Sony TV is a great center piece. It does a lot more then just stream shows and the features built into it are better then any tv I’ve ever owned! Highly recommend
