Why Pick It​

LG C3 Series TV/OLED65C3PUA​

The picture quality on this TV is nothing short of stunning. It’s the kind of clarity that makes you appreciate the detail in a way you never thought you could. Colors pop, blacks are as deep as the night sky, and even the most mundane content feels cinematic. Honestly, I’m still in awe. The OLED display, paired with LG’s 4K processor, makes watching movies and shows a mesmerizing experience. For the value, it’s hard to imagine anything better.

But, there are two elements that keep it from true perfection. The first is the menu system, which feels like it’s stuck in a bygone era. It’s clunky, outdated, and unnecessarily complicated. Sure, everything works, but navigating the system is far from intuitive. After spending a significant amount of time trying to get it right, I still feel like I’m fighting the menu rather than enjoying the experience.

Then there’s the remote. Oh, the remote. I’m honestly baffled that LG has yet to design a practical, easy-to-use remote. Holding it in your hand feels like a game of hide-and-seek. The volume buttons, for instance, are placed in such a way that you can’t find them easily, especially in the dark. I’ve lost count of how many times I’ve had to fumble around to find the right button. And don’t even get me started on how non-intuitive it is. LG should have done better by now. The remote isn’t just clunky—it’s downright frustrating, and it’s an unfortunate blemish on an otherwise exceptional TV.

The picture on this TV? Stunning. It’s not just “good”—it’s otherworldly. Watching it feels like the person on screen could step right into my living room. Every detail is crisp, every color vibrant, every shadow deep and rich. I’ve seen a lot of televisions in my time, but nothing compares to this. It’s as though reality itself has been translated into pixels, and I’m witnessing it firsthand.

And then there’s the remote—where do I even begin? It’s not your typical clicker; it’s a revolution in your hand. The remote works like a computer mouse, with a scroll wheel that lets you glide through menus effortlessly. It’s intuitive, fluid, and faster than anything I’ve ever used. Sure, there’s a slight learning curve, but once you get the hang of it, navigating through apps or typing in login credentials feels like a breeze. It’s the kind of feature that makes you wonder why it hasn’t been a thing for years.

When it comes to picture quality, the TV auto-adjusts based on the content you’re watching—whether it's a high-paced video game or a slow-burn drama. With every flip of the input, the TV adjusts, effortlessly optimizing the settings. And let’s talk about the OLED. The blacks are deep, like night itself. That’s the magic of OLED—no gray-out, just pure inky blackness that brings the rest of the picture to life. The viewing angles are superb; no matter where you sit, the picture looks just as incredible. It’s a treat for your eyes from every angle.

LG B3 Series TV/OLED65B3PUA​

Let's talk about the picture. If you've ever been disappointed by a TV’s image quality, you know how important this is. But this? This was nothing short of jaw-dropping. Streaming 4K content or gaming on my PS5 felt like I was experiencing it for the first time. It was as if the TV was tailored to make everything look its best. And you don’t have to take my word for it—there’s an A.I. setting that optimizes the picture to suit your preferences. I couldn’t get enough of how everything from movies to sports and games just looked... alive.

In terms of functionality, the interface is lightning fast. No lag, no hiccups, just smooth sailing. The remotes are incredibly easy to use, and the MagicRemotes really live up to their name. You can point, click, or just use the buttons—whichever you prefer. Navigating the homepage is a breeze, and I love how customizable the apps are. One of the best tips I received from an IT-savvy friend was that when you invest in a TV like this, you’re not just buying a screen—you’re buying a whole computer system. And I’ve learned that firsthand. The quality here? Worth every penny. Going forward, I’ll never buy a TV any other way.

As for sound, I have no complaints. The quality is solid. But here's the real magic: it uses the walls and other nearby surfaces to project the sound, creating a richer, fuller experience. It’s like having surround sound without the extra speakers cluttering the room. Plus, there are multiple sound settings to fine-tune everything to your liking, which makes it feel like the TV is constantly adjusting to your environment.

The deep blacks, the striking contrast, the razor-sharp clarity—everything just popped. It felt like I was finally experiencing what OLED was meant to be. And when I switched to game mode? It took me back to the glory days of plasma TVs, but without the drawbacks of the LED I had before—goodbye, washed-out colors and screen blooming. It’s like stepping into a whole new world. And for the price? Honestly, perfection.

That’s one thing. But what really sent me over the edge was a movie I watched on Prime. Despite paying for an ad-free experience, I was bombarded with commercials—yes, commercials, right in the middle of my movie. Amazon’s greed has reached new heights, and frankly, I’ve had enough. After paying hundreds of dollars each month for Xfinity, there’s no way I’m tolerating ads, especially when I’ve already paid for a commercial-free service. After this month, I’m done with Amazon. I’ve already emptied my cart and am returning the TV before the deadline. Until they change their policy, my relationship with Amazon is over. It’s frustrating to love a product and then have it tainted by corporate decisions.

On a brighter note, the TV itself is a technical marvel, and the minimalist design is exactly what I was looking for. For over 20 years, my living room was a no-TV zone. But when we finally decided to bring one in, we knew it had to be something sleek and powerful—this 4K LG met all those criteria without breaking the bank. At first, we were a bit confused by the home screen and the preloaded apps; they felt a bit cluttered and overwhelming. But once we hooked up an Apple TV and a small soundbar, everything clicked. The sound was rich, the picture was stunning, and the simplicity of the setup made it all worth it. Our neighbors had recommended LG, and I can confidently say they were right. This TV doesn’t just meet expectations—it exceeds them in every way that matters.
