TCL 4-Series 75S455 75"
The 75-inch 4K LED panel with Dolby Vision IQ and HDR10+ support delivers bright, detailed HDR content for a large-screen experience. Its Roku TV platform offers simple navigation and access to major streaming apps, while VRR at 60Hz provides smoother motion for casual gaming. This TV is best for budget-conscious buyers who prioritize a big screen for mixed viewing, though its gaming and sports scores are modest.
Resumen
The 30-Second Version
The TCL 4-Series 75S455 is a budget 75-inch 4K TV with surprisingly good HDR support but a 60Hz panel and weak audio. Gaming and picture quality scores land in the mid-30s out of 100. Buy it for size and price, not performance.

Performance
The display is a 75-inch 4K LED panel with a 60Hz refresh rate and VRR. HDR support is actually the bright spot here, sitting in the 98th percentile of our database. Dolby Vision IQ and HDR10+ are both on board, which is more than you usually get at this end of the market. But the rest of the picture quality story is rough. Picture quality overall sits at the 36th percentile, and gaming performance is at the 37th. The 60Hz panel holds it back for fast motion, and LED without local dimming means blacks look gray in a dark room. Audio is a weak spot too, landing in the 13th percentile. Plan on a soundbar.

vs Competition
Stacked against the LG OLED evo C5, Samsung QN990F, or Sony BRAVIA 9, this TCL isn't even in the same conversation. Those sets cost several times more and deliver OLED blacks, 120Hz-plus panels, and real HDR brightness. The TCL's HDR format support is nice, but the panel can't back it up the way those flagships can. Against the Hisense U8 Series, the TCL loses on brightness, refresh rate, and audio. The Roku Pro Series is a closer budget fight, but even that has better smart features and connectivity. The 4-Series wins on one thing: raw screen size per dollar.

Precio
Value & Pricing
Without a listed price, it's hard to call this a slam dunk. But the 4-Series has always been TCL's budget line, and a 75-inch panel for under a grand is the usual pitch. You're paying for size, not refinement. The HDR support is genuinely impressive for the class, but the 60Hz panel and weak audio mean you'll likely spend extra on a soundbar. If you can find this on sale and just want a big screen for Netflix and casual sports, it's fine. If you're paying anywhere near mid-range money, you can do better.

Overview
The TCL 4-Series 75S455 is a big screen for not a lot of money. You get 75 inches of 4K LED, Dolby Vision IQ, HDR10+, and Roku TV built in. That's a solid feature list for a budget panel. But the scores tell the real story. Gaming lands at 33.9 out of 100, movies at 28.7, and sports at 30.1. This is a size-first TV. If you want a huge display for casual viewing and don't care about deep blacks or fast refresh rates, it does the job. If you want performance, keep scrolling.
Common Questions
Q: Is this TV good for gaming?
Not really. It has a 60Hz panel and VRR, but gaming scores 33.9 out of 100 in our database. Casual gaming is fine, but fast-paced shooters or racing games will show motion blur and input lag.
Q: Does the TCL 75S455 have good picture quality?
It's average at best. HDR support is excellent with Dolby Vision IQ and HDR10+, but overall picture quality sits at the 36th percentile. Blacks won't be deep, and bright scenes can look washed out compared to higher-end sets.
Q: Do I need a soundbar with this TV?
Yes, probably. Audio quality ranks in the 13th percentile of our database, which is near the bottom. The built-in speakers will get the job done for news and sitcoms, but movies and games will sound thin.
Who Should Skip This
Skip this if you care about gaming performance or audio quality. The 60Hz panel and bottom-tier speakers will frustrate anyone who plays fast-paced games or watches action movies without a soundbar. Also skip it if you want a TV that'll still feel current in three years. The smart features and connectivity are already behind the curve.
Verdict
This TV is for someone who wants the biggest screen possible and doesn't want to think about specs. Casual streamers, sports fans who don't mind a little motion blur, and anyone putting a TV in a bright living room where black levels don't matter much. It's not for gamers, home theater nerds, or anyone who notices bad audio. If you just want 75 inches of Roku-powered 4K and you find it cheap, go for it. Otherwise, save up a little more.
