TCL 4-Series 75S451 75"

75 inches of 4K for $799 is the headline, and the 77th percentile connectivity with 4 HDMI ports and eARC is a genuine strength. But the 36th percentile picture quality and 60Hz panel mean you're trading visual performance for size. It's a fine casual streaming TV, not a home theater or gaming display.

Let's talk about what this panel actually does. The display and picture quality rankings, 38th and 36th percentile respectively, tell the real story here. This is a standard LED panel without local dimming, so contrast is limited and HDR highlights won't punch the way they do on a mini-LED or OLED set. The HDR score lands at the 64th percentile, which sounds okay until you realize that HDR10 without meaningful peak brightness is more of a checkbox than a feature. You'll get the wider color gamut, but don't expect specular highlights that make you squint.

Audio is dead average at the 50th percentile, with 30W of total output and Dolby Digital Plus decoding. That's fine for a bedroom or apartment, and the eARC port means you can easily add a soundbar later. Gaming sits at the 45th percentile, which is about what you'd expect from a 60Hz panel with HDMI 2.1 in name only. There's no VRR or ALLM to speak of, so console players will get 4K at 60fps and nothing more. The smart platform is the quiet hero here, at the 63rd percentile, with Roku TV plus Siri, Alexa, Hey Google, and AirPlay support covering basically every ecosystem.

Stacked against the competition, the 75S451 is playing a different game. The LG C5 Series OLED55C5PUA and Sony BRAVIA XR XR77A95L are OLED sets that will absolutely embarrass this panel on picture quality, though they cost several times more. The Samsung Neo QLED QN70F brings mini-LED brightness and local dimming that makes the TCL's HDR look flat by comparison. Even the Hisense U8 Series 65U8QG, which is closer in spirit to a budget big-screen, offers quantum dot color and far better HDR performance. The Roku Pro Series 55R8C5 is the most interesting comparison, same platform, better panel, smaller screen. The TCL wins on size per dollar and connectivity, but loses on every picture quality metric that matters.

At $799 for a 75-inch 4K TV, the price per inch math is undeniably attractive. You're paying roughly $10.65 per diagonal inch, which is cheap for this size class. But value isn't just about size, and the 36th percentile picture quality means you're trading visual performance for square footage. The connectivity and smart features punch above the price point, which helps, but the social proof at the 27th percentile and a 3.9/5 rating from just 10 reviews suggest buyers aren't exactly raving. If your priority is a massive screen for casual viewing and you can live with average picture quality, this is a reasonable deal. If you care about contrast, HDR pop, or gaming features, that $799 is better spent elsewhere.

The TCL 4-Series 75S451 is a 75-inch 4K LED TV that lands at $799, and for that money you're getting a whole lot of screen. The connectivity story is the strongest thing here, sitting at the 77th percentile in our database, with 4 HDMI ports, eARC, Ethernet, and Wi-Fi 5 on board. That's more I/O than plenty of pricier sets, and it makes this thing genuinely easy to slot into a living room setup. The Roku smart platform is also a known quantity, simple, fast, and loaded with every streaming app you'd actually use.

But the picture is where the compromises show up. Display quality sits at the 38th percentile and picture quality at the 36th, which means this is a budget panel wearing a big-screen costume. HDR10 and HLG support are there on paper, but at the 64th percentile for HDR, you're getting the format without the brightness to really sell it. The 60Hz refresh rate and 45th percentile gaming score mean this is not a set for competitive players. It's a big, affordable screen for casual streaming and sports, not a home theater centerpiece.

Skip this one if you care about picture quality, gaming, or long-term reliability. The 36th percentile picture quality and 38th percentile display ranking mean this panel is firmly in budget territory, and the 45th percentile gaming score with no VRR or ALLM makes it a poor choice for console or PC players. The 27th percentile social proof and 3.9/5 rating from just 10 reviews, including one report of a unit arriving damaged, don't inspire confidence either. If you're building a home theater, want HDR that actually pops, or need a display for fast-paced gaming, put your $799 toward a smaller but better panel like the Hisense U8 Series or save up for something in the mini-LED or OLED class.

The TCL 4-Series 75S451 is a big screen for a small price, and that's the whole pitch. The 77th percentile connectivity and solid Roku platform make it easy to live with, and 75 inches of 4K for $799 is hard to argue with on paper. But the 36th percentile picture quality is the elephant in the room. This is a TV for people who want size and simplicity above all else, casual streamers, sports fans, families who need a big screen in a bright room where absolute contrast doesn't matter. If you're shopping for a home theater centerpiece or a gaming display, keep looking. If you just want a huge Roku TV that works, this does the job.
