    Amazing picture with versatile features

    Amazing! That is the only word that really describes the picture and quality this TV has shown since purchasing. I've had this TV for around 8 months now and I only get more impressed with it as the time passes. Not so super technical review to follow. Backstory on purchasing TV: I've been doing enterprise IT in some form or another for the last 25+ years and had been planning on buying an OLED TV to replace my current TV at the time as a treat to myself for completing a major project at work I was heading. One of those "I work hard so I should be able to enjoy some fruits of those labors" situations. I scoured the interwebs researching, pricing, and comparing all the TVs I could within the criteria I wanted to stay in. I didn't want it to be overwhelmingly huge or carry a $5k+ price tag which counted out most anything 83" or bigger. Probably a blessing in disguise as I've found that 75"-80" is about perfect for the space this TV would be calling home in my basement "man cave". My TV at the time in the cave was a 75" Hisense that filled the screen size void and was great for watching sports or everyday programming but it lacked the quality and refinement I was used to from a Sony Bravia or a Sharp AQUOS from back in the day (relatively speaking) like the 60" AQUOS I bought from Best Buy fifteen years ago that is still running strong in my living room to this day. This was especially apparent when watching movies that pandered to high definition scenes like Star Wars/Star Trek or darker scenes in shows or movies where the blooming effect of budget LED backlighting overwhelmed the scene that left my wife and I almost making up what we were seeing on the screen. Time since purchase: During the 8 months I've had this TV I have been nothing but impressed with the picture quality. It is crisp, the motion flow on panning scenes are absolutely perfect, and I do not regret one bit going with an OLED over the mini LED during dark scenes. Zero and I mean ZERO blooming effect on this TV. There are times I am questioning whether the TV is even on when there is a long dark transition between movie scenes. My wife, who does not care about picture quality most of the time, even says "Wow that is a really sharp picture!" when we are watching movies now. Even months past getting this TV I cannot express enough how much I enjoy sitting down and watching even the most basic show or movie on it. I've found myself rewatching movies I haven't watch in years, such as the original Blade Runner, and appreciating all over again the detail and care that went into making the movie immersive and life like. To add to the flavor this Bravia 8 is very vendor diverse friendly. Since buying this TV I purchased a Pioneer Elite VSX-LX505 AV receiver to replace my old Yamaha Aventage 4K AV receiver and was once again overly impressed with the jump in picture quality this Bravia 8 presented. I didn't appreciate at the time when I first got the TV how much of a bottleneck my old receiver was placing on the video quality this TV was capable of. It was like turning in on for the first time again. While I do use the Google TV features from time to time I generally run most of my media viewing through a Roku Ultra (2025 model). This TV plays ball with the Roku really well. Even with everything running through my AV receiver all devices work together harmoniously through eARC and I only have to use the one Roku remote to run it all. Power, volume, etc... It is a testament to manufactures making available what the bulk of consumers really want in regard to versatility vs pigeonholing people into their narrow visioned ecosystem. Would all of this have been a seamless set up if I had the equivalent Sony receiver and so on? Sure. I don't think anyone could debate that but I thank Sony a thousand times over for remembering that there are other products out there that a person may have invested their hard earned money on and want it to work with all their other devices at least on the functionality level. There you have it. Hope it helps.

    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.

    Excellent tv with great perks!

    I couple years ago I bought an 86 inch LG LED for my den. It’s an excellent tv with great brightness but the blooming effect and cloudy blacks would irritate me and I regreted not getting an OLED but the cost for the size I wanted was prohibitive. I bought a ps5 pro and wanted to replace my bedroom tv where I’ve been gaming more due to an injury. I am beyond impressed with this Sony OLED!! True black is just so beautiful lol. Watching fire works or any scene where something is bright and the bulk of the screen is dark is amazing! Like light sabers look so good. The only downside is brightness. It’s still plenty bright but my LG looks a touch better on purely very colorful bright scenes like a green tropical jungle but the Sony destroys it with a scene of a city at night and the insane sharpness of the buildings with some windows lit and some off and cars and street lights. The Sony is very easy to change setting to bright scenes it’s just two button pushes. If you have the cash to pay 2k more for the next model up I’d say give it a strong look. If you dont you will still LOVE this tv like i do. If I had to give up one I’d give up my LG even though it’s bigger. Beside the picture there’s a ton of other benefits where Sony destroyed my LG. Having google tv as the operating system is vastly superior to the webos of my LG. Normally I use Amazon fire cube with two echo shows for my sound system. The echo show is pretty impressive just fyi. Using the earc hdmi I could output to my show speakers but sometimes it got wonky. I was a bit more impressed with how google integrated my tv watching. It displays what I’ve watched across multiple streaming services and linked to my movies anywhere account. I’ve stopped using my fire tv cube. I had liked the cube because I could run my xfinity cable through it as well but the Sony tv controls my cable better than the fire cube. I’m impressed with how it controls my other equipment. I decided to go all in on Sony and bought the Sony quad speaker system (amazing!but probably overpriced. Also works with the tv to make it a center channel ), I have a ps5, Sony 4K Blu-ray player (you get better picture than streaming) and Sony wh1000xm5 headset. It’s insane how well these all work together so smoothly. I can use my primary tv remote to easily control everything with no setup needed including videos on my ps5. You can have audio out to both the tv and the headset in case on person needs it louder. If you take your headset off it pauses your show. When playing video games it knows and gives you special gaming options for picture control and other neat features. Tbh some of the hype about the gaming options and "knowing what your watching to make better picture" is a little meh but my lg had similar claims that were also hype. However you’ll easily pick you’re preferred mode it’s stupid easy to change. It does however know if your watching Dolby vision and give you real different options that are impactful. It doesn’t have hdr10 for some reason which is a bummer but the pros out weigh the con. Other con is only 2 hdmi 2.1 ports but they have the cool gaming features which you have to turn on in the setting but the other 2 hdmi ports still give you Dolby vision etc so only needed for gaming. If you get the Sony quad you get an extra hdmi 2.1 for your ps5. I have both ps5 and xbox X. I love seeing in the settings that I get the full advantage of ever benefit. I believe the ps5 on this Sony dosent do the 1444 or whatever that is but I’ve also heard it does so if that’s important to you look into more. Spider-Man 2 on this tv with the pro looks stupid good!!! Another cool thing is the tv feet have 4 different placements. narrow and wide with 2 different height settings you’d be surprised how nice that is. Makes it easy to slide things like a soundbar or dvd player under the tv. The remote control is kinda ugly with some odd button placements and no back light but it has lots of good options and controls my equipment including cable box well. Ive had Samsung, tcl, and lg but I think moving forward im going Sony very impressed

This is particularly beneficial for displaying a broad range of colors, ensuring that the colors are not only rich but also true to life. Hope this helps! Brilliant pictures.
