When it comes to premium television technology, two heavyweights are vying for the top spot: the Samsung QN900B and the LG OLED77Z3PUA. Each model presents a compelling case for why they deserve to be your next entertainment centerpiece, but they do so in fundamentally different ways.

On one hand, the Samsung QN900B boasts its Infinity Screen and the Quantum Matrix Pro with Mini LEDs, promising a visual experience that claims to push the boundaries of color and contrast. The Neural Quantum Processor 8K aims to elevate your viewing pleasure by utilizing advanced AI to deliver stunning upscaling and immersive sound.

Conversely, the LG OLED77Z3PUA takes a more traditional approach with its self-lit pixels, which provide rich colors and deep blacks, making it a favorite for cinephiles who prioritize picture quality. With its Brightness Booster Max, it claims to achieve brightness levels that challenge the perception of OLED limitations.

So, which technology reigns supreme? Is the innovative approach of Samsung worth the potential drawbacks of its edge-lit design, or does LG’s reliance on self-lit pixels deliver a more authentic viewing experience? Let’s dive into the specifics and see how these two TVs stack up against each other.

Hey everyone.

I'm in the market for a new TV and caught between the SAMSUNG QN900B and the LG OLED77Z3PUA. Both sound incredible, but I could use some help deciding based on a few key factors.

First off, picture quality. The Samsung boasts this Infinity Screen and Quantum Matrix Pro tech, which sounds like it could deliver some crazy detail with those mini LEDs. On the flip side, the LG has self-lit pixels with 100% Color Volume, which I think means amazing color accuracy and contrast. Has anyone seen a side-by-side comparison or have thoughts on which one really pops more?

Then there's sound quality. The Samsung mentions Atmos sound, but how does that stack up against the LG's overall audio experience? Do I need to invest in a soundbar for either, or are they good on their own?

As for the system, I’m curious about the user interface and smart features. I've heard mixed things about Samsung's Smart Hub. Is it smooth and intuitive? Does the LG have a better setup for streaming and apps?

Lastly, are there any potential downsides to either model? I’ve read that OLEDs can have burn-in issues, while I've heard some say that Samsung’s processing might not be as good as OLED for certain content.

Thanks for any insights you can share!

Man, I gotta vent about my Samsung QN900B TV. I dropped 7 grand on this thing, and guess what? The remote barely works! Seriously, I've been dealing with nothing but problems with this controller. It’s super frustrating! You’d think for that price, the remote would be smooth sailing, right?
 
So, I’ve got this Samsung QN900B Series TV, and honestly, it’s pretty awesome. But there’s one thing that’s really bugging me. Amazon suggested this fancy slim-line mounting bracket by Samsung, which is kinda pricey. But here’s the kicker: the pro installers they recommended said it wouldn’t even work with my TV! Apparently, it only has one screw per bracket plate, and the mounting plate isn’t even inset on the back. So, it’s not gonna hold on very securely at all. Talk about a hassle!

Got myself a Samsung QN900B TV, and let me tell you, I scored big! The box was a bit banged up, but I saved a sweet $400. The TV itself? Flawless! It was wrapped up tight, not a scratch on it. Plus, the customer service was awesome, and it even arrived a day early. Can’t beat that!

So, I originally ordered the QN800B, but when it showed up dead on arrival, I decided to level up and go for the QN900B instead. Best move ever! The picture quality is simply amazing—like, seriously stunning. There's a bit of blooming here and there, but it's nothing I can't handle. Fingers crossed Samsung rolls out some firmware updates to fix that up a bit.

One little hiccup I ran into was that the one connect box gets super hot after a long binge session—like, I’m talking 6+ hours. But I just grabbed a little fan to keep it cool, and now it’s all good!
 
Man, let me tell you about the SAMSUNG QN900B Series TV – it seriously doesn’t get enough credit! I recently tried out the Sony 65 Inch 4K Ultra HD TV A95K Series, you know, the BRAVIA XR OLED Smart Google TV with all those fancy features for the PS5. But honestly? The Samsung totally blows it out of the water! I’m so glad I decided to stick with Samsung. They really know how to make a killer TV!
