Our Take

Best for: Budget-conscious shoppers who want a very large screen for movies,, and casual gaming.

The TCL 75S551F is a straightforward way to get a massive 75-inch 4K screen into your living room without spending a fortune. You're buying it for the size and the smart features. The built-in Fire TV platform is a major plus, putting all your streaming apps, live TV, and even Alexa voice control in one place with the included remote. For gaming, the Game Accelerator 120 and Auto Game Mode are welcome features that should reduce lag, making it a decent option for console gamers who want a big display. Where this TV makes compromises is in its core picture technology. It uses a standard LED backlight, not the more advanced mini-LED or OLED panels found in higher-end models. This means you won't get the same extreme contrast, perfect blacks, or peak brightness. HDR PRO+ support for Dolby Vision and HDR10+ is great, but the TV's hardware will limit how effectively it can show those enhanced formats. The sound from the built-in speakers is also typical for a TV this thin - adequate for daily viewing but you'll want a soundbar for movies. At this sale price, it represents strong value. You are trading some peak picture performance for an enormous screen size and a full smart TV system. If your priority is a cinematic, wall-filling experience for movies,, and gaming on a budget, this TV delivers that.

Price Analysis

At $479.99, this is a good price for a 75-inch TV from a known brand. The 30-day average was $591.76, so the current sale is about $110 lower. The 90-day average is $542 and the 180-day average is $522, so this price is better than recent trends and close to the lowest it's been over the last six months. It's a good time to buy.

Common Questions

Does this TV have a built-in camera for video calls?

No, this model does not have a built-in camera. You would need an external webcam compatible with the Fire TV platform for video calls.

Can I mount this TV on the wall?

Yes, it is VESA mount compatible. You will need to purchase a wall mount bracket separately that supports the TV's size and weight.

What's the difference between the S5 and a more expensive TCL Q6 or Q7?

The main difference is picture quality. The Q6 and Q7 series use QLED technology with quantum dots for better color and brightness, and often have more local dimming zones for improved contrast.
