TCL S45K Series 75S45K 75"

The TCL 75S45K is a massive 75-inch 4K TV for just $650, and its picture quality is shockingly good for the price. You'll need a soundbar because the built-in audio is terrible, and HDR is just okay. But if you want a huge, great-looking screen on a budget, this is the one to get.

The AiPQ processor does some heavy lifting here, pushing picture quality into 'one of the best on the market' territory for its class. Colors look accurate and the 4K clarity is sharp. The 120Hz refresh rate keeps motion smooth for sports and gaming, but the HDR performance is underwhelming, stuck in the bottom third of TVs we've tested. Brightness peaks at 400 nits, which is fine for a dim room but won't make HDR highlights pop the way they do on pricier sets. The real weak spot is audio. It's thin and lacks any punch, so you'll absolutely want to budget for a soundbar.

Stacked against the Hisense U7 Series 75U75QG, the TCL wins on pure value and size for the dollar, but the Hisense will smoke it in HDR brightness and gaming features thanks to mini-LED and a higher peak luminance. The Roku Plus Series 75R6C7 offers a simpler, arguably better smart TV experience for a similar price, but its picture quality doesn't match the TCL's processing. You're not even in the same conversation as the Sony BRAVIA 9 or LG G5 OLEDs, which cost several times more and deliver a premium experience in every category. The TCL's game is giving you 90% of the big-screen fun for 20% of the price.

For $650, the sheer size of this thing makes it a screaming deal. You're getting a 75-inch canvas that delivers picture quality far better than it has any right to at this price. The value proposition is simple: you're trading top-tier audio and HDR fireworks for a gigantic, good-looking screen. If you can live with that trade-off and plan to add a soundbar, this is one of the best budget big-screen buys out there.

The TCL 75S45K is a massive 75-inch screen for a price that feels like a typo. At $650, you're getting a big, bright enough 4K TV with Google TV built right in, which means no dongles and no fuss. The picture quality is a genuine standout for this budget tier, landing in the 85th percentile in our database. That's seriously impressive for a TV that costs less than some people's monthly car payment.

But you don't get a screen this big for this cheap without some corners getting cut. The audio is a real letdown, sitting near the bottom of the barrel at the 13th percentile. And while it has a 120Hz panel and HDMI 2.1 for gaming, the overall gaming score is just middle of the pack. This is a living room hero for movie nights and casual streaming, not a competitive gamer's dream monitor.

If you're a home theater enthusiast who cares about deep blacks and punchy HDR highlights, look elsewhere. The lack of local dimming and low peak brightness means this TV can't do justice to 4K Blu-rays or high-end streaming. Gamers who need the lowest input lag and best VRR support should also pass, as this set is built for size and streaming, not twitchy competitive play.

This TV is for anyone who wants to fill a wall without emptying their bank account. It's perfect for family movie nights, binge-watching shows, and casual sports viewing in a room where you can control the light. Just know you'll need a soundbar from day one, and don't expect it to be a bright-room HDR champion. If you want a massive, easy-to-use screen that looks great with most content, the TCL 75S45K is a no-brainer.
