I always liked TCL style flat screen TVs. I now am the proud owner of TWO of these same TVs and the picture is awesome! The User Interface is awesome! The setup is easy peasy lemony squeezy! The BEST part? It doesn't break the bank! I got this 55 inch beauty with a crisp clear screen that looks like you can reach right into it, as if it was a window, for less than $300 after taxes! Even the remote is awesome, as it has a microphone and Alexa services built right into the device itself. You simply can't go wrong. Once it gets here, the FREE unboxing and delivery to the room of choice allows you to evaluate the condition of your TV and if something is wrong or broken, you can refuse the shipment and it will be taken back for a refund or an exchange. No questions asked. We have had the first one for a year now. This newer one is the same generation, but still brand new in the box that has never been opened. Your money is not badly spent here, it's worth every penny for what you get, and do you get a LOT of good stuff! Yes, it has a VESA pattern on the back for stand mounting, as my older 55 that we had since 2018 just died, so we got this one and for only a quarter of what we paid in 2018! My next one I'm saving for will be the 75 inch beauty for my very large master bedroom, which will only take me about 4 months to save for! Yippee! After that, our TV needs will be fully met! Happy House, Happy Spouse!

I have owed this TV, and watched it daily, for five months now. I can honestly say I regret purchasing it. There are so many negative traits, I don’t know where to start. It is slow. Sometimes it can take up to 30 seconds to change the channel, or to switch apps, or to even stop playback on a streaming show. It has many glitches… for example, sometimes when I am playing PS5, the screen will just go to black, it will still have audio, but the screen will be completely dark and I I’ll have to relaunch the system to fix it. On the home screen, there is an option to continue watching a show where you left off, but it doesn’t work correctly, and it will start the show on some past episode that you already watched, and you have to go through the hassle of going back to the menu to find the correct show, which since this TV is so clunky, is a real pain in the butt. Speaking of the home screen, it is one big, annoying advertisement for Amazon. Also, this TV does not display old TV shows properly. Any show from the 1980s or earlier, before the advent of widescreen technology, will appear crushed on the screen, making it impossible to enjoy. I actually talked to TCL technical support about this, and they are aware of it, but offered no solutions. Also, you cannot download the Spectrum app on this TV. Because for some reason, Amazon considers Spectrum a competitor they won’t allow you to download their app, so if you use the app to watch spectrum TV, you’re out of luck. How pathetic is that? It’s not enough that Amazon makes $1 billion a day, they have to crush the competitors too. Like allowing people to watch a. competitor’s app with somehow affect their bottom line. Ridiculous. It does have a nice picture, but the sound is average at best, and sometimes I have to turn the volume up to above 70 to hear the dialogue, depending on the app I am using. The really interesting thing is I also own a 55 inch TCL TV with a Roku operating system, and it is great. So IMO the issue is not with the manufacturer, TCL, but with the operating system, Fire TV. I would highly discourage anyone from purchasing any TV with the Fire TV operating system, and in particular this TV. EDIT: It’s been over one year since I bought this TV and if I could lower my rating to zero stars, I would. It crashes while watching shows. It takes forever to load apps, or to scroll the menu. It’s cheap, and you get what you pay for.

It’s big, bad, and beautiful. Why in the world would anyone spend more than this on a TV when this thing is simply amazing. I read every review on Amazon on this TV before I purchased it. Laggy remote and interface, lack of Xfinity apps.. you name it. Does it take a half second from pressing a button on the remote to translate to the TV- yes definitely. The missing Xfinity app- it’s just in the App Store to download just not preinstalled. Easy. TV was delivered fast by two nice guys in a big Amazon truck on a Saturday. They simply asked where should we put it. I didn’t select any kind of installation or unboxing. This thing in the box is gigantic, but me and my 12 year old lifted that big box with ease. No damaged packaging, brand new not a returned unit, not a scratch on the box. The packing on this is great, for those worried about it getting shipped, unless you dropped it off the truck, I would trust delivery. It took longer to unbox simply due to size than hooking up. Had issues with my router blocking the connection to Amazon to update, but once I figured that out TV updated itself then I linked to my account. I also purchased the bundle with the matching TCL 2.1 soundbar and that was plug and play out of the box with this TV. Installed the missing apps that I had on my last Roku TV, hooked up Xbox, which was also automatically detected and plug and play, and done. Color out of the box was perfect for me. The TV with auto switch to the best possible setting for whatever source is feeding it. Some Amazon and Netflix shows were Dolby Atmos, some not. TV sensed that and just adjusted. Clarity and brightness is superb. Xbox games are fluid and colorful as expected. The size is a monster compared to our older 55” TCL Roku TV. Needed a larger stand as the legs are far wider than the 55”. Like I said, I’m not sure why you would need a $2,000 TV, this does ball that at a fraction of the price. Lastly since it’s Fire TV I get things like my Amazon Music app which thumps with the 2.1 soundbar’s subwoofer. You get Alexa- which now my Echo dots around the house can control the TV. Is awesome. Been buying TCL TV’s for years with no issues. We have 3 in the house. I would recommend this to anyone.

There are televisions, and then there are immersive entertainment experiences. The TCL 75-Inch Class S5 UHD 4K LED Smart TV (75S551F, 2024 Model) is not just a screen—it is a window into a world of breathtaking color, cinematic sound, and seamless smart integration. Picture Quality That Stands Out Clarity, contrast, and color—these are the hallmarks of a great TV. The 4K Ultra HD resolution on this display renders every detail with razor-sharp precision, while the Dolby Vision, HDR10+, HDR10, and HLG formats elevate contrast and color accuracy for a picture that feels alive. Whether you're watching a blockbuster movie or the big game, the TCL S5 Series ensures a premium visual experience. A Smart TV That Thinks Ahead Why waste time scrolling when you can speak your commands into existence? With Fire TV built-in, you have instant access to Netflix, Prime Video, Disney+, and thousands of other streaming options. But what truly sets this model apart is Alexa integration—just say the word, and your TV obeys. No clunky remotes, no endless scrolling. Designed for Gamers, Built for Action In the world of gaming, every millisecond counts. That’s why the Game Accelerator 120 feature delivers 120Hz Variable Refresh Rate (VRR) for buttery-smooth motion. Add in Auto Game Mode (ALLM) and you have a TV that reacts as fast as you do, eliminating lag and maximizing performance. Audio That Commands Attention A great picture is only half the story. Dolby Atmos and DTS Virtual:X create an immersive soundstage that brings explosions, dialogue, and soundtracks to life. For true home theater enthusiasts, a soundbar may still be a wise addition, but the built-in speakers hold their own better than most in this category. What You Need to Know Let’s be clear—at this price, you are not getting OLED. Viewing angles could be wider, and for those who crave deeper blacks, the lack of local dimming may leave something to be desired. But in its class, the S5 delivers exceptional value—competing with TVs twice its price and leaving budget competitors in the dust. The Final Word: A Must-Have for Value Seekers If you’re looking for a massive, high-performance 4K TV with smart features, fast gaming response, and brilliant visuals—this is the one to buy. The TCL 75-Inch S5 UHD 4K LED Smart TV is a powerhouse of entertainment, designed to impress without breaking the bank. Order today, and elevate your home entertainment experience to the next level.

UPDATE 12/10/24: While everything I wrote still stands, I have discovered you CAN NOT disable the SLEEP TIMER.! This is a HUGE DESIGN FLAW and IMMENSELY AGGRAVATING & INCONVENIENT! Example: Every time I pause a show (to answer phone etc), the TV goes into Sleep Mode and I have to Start the process All Over again; Go to & click Hulu (any app), click my name, scroll to show I was watching, Click on show, then Click "play". Unbelievable waste of time and IRRITATING to No End! While researching how to disable the sleep timer, I found so many forums with many, manh people discusing this issue and how P!ssed off everyone is about this horrible issue. Why they don't have "Never" option in the sleep timer is the most idiotic oversight. If I had discovered this within my return window, I would have got rid of this TV. Unless they fix this in the future, I will NEVER EVER buy another Fire TV! ROKU is so much more user-friendly and not trying to force things on the user (like Amazon TV). Are there work arounds? Yes there are but they are only temporary and jusr another step you have to redo offten. The Color is fantastic and the picture is pretty great as far as backlight, brightness, and sharpness. It seemed smaller than my last TCL 55" but I measured it and it was the same size. I'm still trying to get used to the Home page layout of the Fire OS - I prefer Roku. 3 things that bothered me about this T.V.: 1.) I'm disappointed that the 3.5 mm headphone jack will not output to my multimedia speakers (with subwoofer), like my last TCL. I did all the proper settings and no sound at all. Luckily, the onboard TV speaker sound is better than most TV's if you tweak the settings a bit. It's good enough that I didn't feel compelled to buy a sound bar immediately (may get one eventually). 2.) Like other reviews mentioned, there is a lag sometimes. It's just enough to be annoying but nothing to pull your hair out over...so far. I will update if anything gets worse with time. 3) This is my worst pet peeve about this TV - I hate the remote! It's too long, overly sensitive (easy to trigger), and not very efficient with the button layout imo. But I have small hands so maybe that's why. Having Alexa makes up for some of my dislikes. All in all, this is an excellent TV for the price and a great deal. I like that it has a Media Player (app) so I can see stuff from a thumb drive right on my T.V. Lets see how long it lasts. The T.V. that I was replacing, a 55" TCL 5 series with Roku, the video went out 4 months after the 4 year extended warranty expired. Good thing I didn't pay for the extended warranty lol.

A Remarkable 75-Inch Masterpiece — TCL Has Redefined Value, Performance, and Home Entertainment Purchasing the TCL 75-Inch Class S5 UHD 4K LED Smart TV with Fire TV (75S551F, 2024 Model) from AMAZON has been one of the most satisfying tech upgrades I’ve made in years. This TV doesn’t just perform well — it delivers a premium cinematic experience that consistently impresses, night after night. TCL has truly raised the bar with this model, offering flagship-level quality at an unbelievably accessible price. Dazzling Visuals That Transform Your Living Space The moment the screen powers on, the 4K UHD panel shows its strength. Colors are rich and lifelike without ever looking exaggerated. The combination of Dolby Vision and HDR PRO+ adds incredible depth, nuanced shadow detail, and brilliant highlights that bring out layers of realism you simply can’t get on lower-end models. Whether you're watching a nature documentary, an action blockbuster, or sports in real time, the image quality is consistently breathtaking. The contrast performance is excellent, and motion handling is smooth and clean — even during high-speed scenes. Simply put, this TV makes everything look spectacular. Immersive Dolby Atmos Sound That Fills the Room A massive screen deserves powerful sound, and the built-in Dolby Atmos system absolutely delivers. The audio is fuller, richer, and more dimensional than expected from an integrated speaker setup. You get clear dialogue without distortion, vibrant highs, and a surprising sense of spaciousness. For many viewers, the TV’s native sound will be more than enough — and for enthusiasts, it pairs beautifully with external audio systems as well. Fire TV Integration That Makes Streaming a Breeze The smart TV experience is one of this model’s biggest strengths. The Fire TV interface is fast, remarkably intuitive, and polished. You get instant access to thousands of apps, streaming services, and channels without a hint of lag. Alexa Built-in makes everything easier. With quick voice commands, you can search for content, control playback, manage smart home devices, and jump directly into your favorite apps — all hands-free. Everyday use feels effortless, responsive, and well thought out. It’s the type of user experience that enhances your viewing habits instead of getting in the way. A Dream for Apple and Amazon Users Alike The inclusion of Apple AirPlay 2 compatibility is a massive bonus that sets this model apart. Casting content, sharing photos, streaming videos, or mirroring your screen from your Apple devices is seamless and reliable. This level of cross-platform flexibility is rare at this price point and makes the TV a perfect hub for modern households with mixed ecosystems. Fantastic for Gaming and Sports Enthusiasts Gamers will appreciate the responsive input control and smooth performance, making gameplay fluid and engaging. Sports fans will love the crisp clarity and smooth motion, even during fast-paced action or quick camera pans. The 75-inch screen makes everything feel larger, more dynamic, and far more immersive. Build Quality and Design That Feel Premium The ultra-slim profile and sleek bezel design make the TV look far more expensive than it actually is. It blends elegantly into any living room, home theater, or office setting. TCL didn’t cut corners — even the construction feels sturdy and intentional. A Price-to-Performance Ratio That’s Practically Unmatched What truly elevates the TCL 75S551F is its enormous value. It brings together high-end features — Dolby Vision, HDR PRO+, Fire TV, Dolby Atmos, Alexa voice capability, AirPlay 2, and a massive 75-inch display — at a price that undercuts many lesser models. You’re not just buying a TV. You’re investing in a complete entertainment upgrade that rivals the experience of TVs costing hundreds more Final Verdict: A Showstopper in Every Sense This TV is an absolute triumph. TCL has delivered a 2024 model that hits every important mark: picture quality, smart features, sound performance, design, ease of use, and exceptional value. It has elevated my viewing experience to a level that genuinely makes movie nights, gaming sessions, and everyday streaming something to look forward to. If you want a cinematic, modern, beautifully designed 75-inch television that far outperforms its price tag, look no further. The TCL 75S551F is a standout winner and an easy, enthusiastic recommendation.
