Why Everyone is Buying the S4 S450G (Full Review)

Introduction: My Journey to the S4 S450G

TV shopping has always been a little overwhelming for me—dozens of brands, cryptic model numbers, and tech specs that sometimes mean more to marketers than actual viewers. Earlier this year, when my old set finally fizzled out, I found myself on this familiar path once again, but with an itch to try something different. That’s how I ended up purchasing the S4 S450G. After seeing its name pop up repeatedly in forums, hearing friends rave about its picture quality, and noticing its buzz online, I wanted to see if it truly lived up to the hype.
Now, after using the S4 S450G daily for over four months, I feel like I genuinely understand what it gets right, where it falls short, and why everyone seems to be buying this TV right now. Below I’ll break down my real-world experiences, share what delighted me (as well as what genuinely bugged me), and hopefully help you decide if this is the TV for you.

Unboxing and First Impressions

Removing the S4 S450G from its packaging was, honestly, a little more exciting than I expected. The TV was well packed but not over-packaged. It came with a slim remote, quick start guide, two AAA batteries, and some of the highest-quality, sturdiest TV stands I’ve seen in this price category.
The design is sleek—minimal bezels that make the screen feel more immersive, a thin profile that didn’t look out of place mounted on my wall, and subtle branding that doesn’t distract from the content. As soon as I powered it up, I was greeted with a setup process that was blissfully simple. The menus were intuitive, and even connecting my Wi-Fi felt nearly effortless.
But my attention quickly moved from setup to the real test: performance.

Picture Quality: Where the Hype Meets Reality

Let me be straight—the S4 S450G’s picture quality was the first (and biggest) reason I understood why it’s creating such a stir. Whether I was watching 4K movies, streaming HD shows, or even gaming, I noticed a substantial jump compared to my last set.

• Sharpness and Resolution: The 4K panel is truly sharp. Sitting just under eight feet away, I could see fine details in nature documentaries and barely any visible artifacts or weird upscaling in standard definition content.
• Color Accuracy: What surprised me was how natural the colors looked out of the box. Skin tones weren’t oversaturated, and I wasn’t bombarded by the neon blues some TVs push. I did end up tweaking the color settings slightly, but honestly, this was more of a personal preference than a necessity.
• Contrast and Blacks: In a dark room, the S450G’s blacks are deep, though not OLED-level. I could still spot some stray backlight, especially during scenes with stark dark-to-light transitions. This wasn’t a deal-breaker for me, but it’s one of the places where the S4 S450G didn’t quite match some more expensive TVs I’ve seen.
• Motion Handling: Fast action scenes in movies and especially live sports were smooth—much better than I expected. I rarely noticed judder or ghosting, which I really appreciated since I’m a big football fan.

One thing that did bother me: in bright daylight, the reflective screen finish meant that direct sunlight could sometimes be a bit distracting. Curtains make a difference, but if your living room is glass-filled, be prepared for some glare during the brightest hours.

Sound Quality: Surprisingly Good (But Not Perfect)

If you’ve owned mid-tier TVs before, you likely know the notorious “tin can” sound. I was bracing myself to invest in an external soundbar right away, but the S450G surprised me. The built-in speakers are, for typical day-to-day use, genuinely above average. Voices are clear, the midrange is strong, and I could follow dialog even at lower volumes.
That said, real bass punch is missing (as expected with built-ins this slim). While music and movies sounded decent, I noticed a lack of depth in soundtracks with heavy bass. For cinephiles or audiophiles, you’ll still want a dedicated sound system, but for news, sitcoms, and casual streaming, the S4 S450G holds its own.

Smart TV Experience and Operating System

The S4 S450G runs on a proprietary, Android-based smart TV OS that’s fast and responsive. I had zero issues with lag even as I loaded up Netflix, YouTube, Disney+, and a handful of smaller streaming apps. The app store is well-stocked, and navigating with the remote is—for the most part—a breeze.
One quirk I noticed: the remote sometimes missed the first click after the TV had been on for several hours, which could be a tad annoying. It’s a minor gripe, but it happened enough times that it’s worth mentioning.

Gaming Performance

As someone who enjoys Xbox and some occasional PC gaming, low input lag and smooth graphics really matter to me. The S4 S450G features a dedicated game mode that’s easy to activate and makes a tangible difference. Once enabled, I noticed minimal input lag—first-person shooters and racing games felt tight and responsive. There's no full-on HDMI 2.1 for 120Hz gaming, but at 60Hz, the motion is fluid.
A small, honest gripe: HDR in games looked good, but not as punchy or dynamic as on some more expensive sets. If you’re coming from a higher-tier gaming display, you might notice this too, but for most gamers (including myself) the overall experience was very enjoyable.

Build Quality and Aesthetics

One of the subtler, but important, aspects of TV ownership is how the product feels day-to-day. The S450G’s chassis is impressively solid, its footprint slim, and it fits well into most modern living spaces. The stand is sturdy and doesn’t wobble, though I did need a second person to help with wall-mounting because of the size and weight.
All the ports are easily accessible along the side, meaning adding new HDMI devices or unplugging peripherals was never a stressful, “jam your hand behind the TV” scenario. Small touch, but much appreciated.

Connectivity and Ports

The S4 S450G gives you three HDMI ports, two USB ports, optical, Ethernet, and ARC support—more than enough for a soundbar, streaming stick, gaming console, and even a media server. Wi-Fi range was solid in my house, and streaming 4K content wirelessly only resulted in a single buffer in four months.
Bluetooth support is here too, making connecting wireless headphones painless. I used this feature more than I expected, especially for late-night movie watching.
