    A Great, BIG TV

    I love this TCL 75-inch S55LR Roku TV. The first thing that stands out is the size—and surprisingly, the weight. Seventy-five inches is huge, and I love it. When it was delivered, two guys brought it to my garage, so I assumed it must be really heavy. Wrong! This TV only weighs about 40 pounds. I was able to bring it into the house by myself, although the box was a little awkward because of how wide it is. I upgraded from an older 65-inch TV to this 75-inch smart TV, and the difference is huge when watching movies, sports, or just regular TV. The picture is sharp and clear, with good color and 4K quality that looks great for streaming. We use YouTube TV for regular television, and the picture right out of the box was amazing. I asked AI what settings might work best, and after making a few adjustments, the picture looked even better. I changed the picture mode to Movie, which made skin tones and surrounding images look more natural. I also adjusted the backlight so the colors wouldn't look washed out. Finally, I moved the sharpness setting to zero to avoid adding unnecessary processing to 4K content. After those adjustments, the picture looks amazing. One of my favorite things about this TV is how easy the Roku system is to use. I have other Roku TVs, so moving apps around the home screen is a breeze. I like to remove the apps I don't use so the ones I use most are right at the top of the home screen for easy access. Everything is simple to find, and switching between apps and live TV is straightforward. The menus are easy to navigate, which is something I really appreciate compared to some smart TVs that can feel overly complicated. It's also nice that Roku offers plenty of free channels, movies, news, and sports for people who don't pay for TV. Being a sports fanatic, it is totally awesome watching all my favorite sports on this gigantic screen. HDR helps provide good contrast and vivid picture quality, while the Motion Rate 240 with MEMC helps keep fast-moving action smooth and clear during sporting events and action movies. I had to look up how MEMC worked, and whatever genius created it deserves a raise. It creates additional frames to help motion appear smoother on the screen. It's way above my pay scale, but I definitely appreciate that someone came up with it for my TV-watching enjoyment! My kids are serious gamers, so they probably wouldn't use a TV this large for competitive FPS gaming, but I can't wait to hook up my Switch and play fun games like Mario Kart. Mario is going to be huge! The TV itself has a very clean design, with little to no bezel around the screen. The three HDMI ports on the back are easy to access for connecting peripherals. The main one I used was the HDMI eARC port to connect my soundbar. Connecting to my wireless home network was also very easy. The quick setup screens walk you through the process step by step. I also like having the option to connect through an Ethernet cable if the Wi-Fi in the house ever gets a little buggy. Another feature I like is Bluetooth personal audio. I can pair my headphones with the TV for private listening, which is great for late-night viewing without disturbing anyone else. Overall, I think this is a great TV for the price, especially if you're looking for a large screen without spending a fortune. It may not have all the premium features of a much more expensive TV, but for everyday watching, streaming, movies, and sports, it does everything I need. I'm very happy with my purchase and would recommend it to anyone looking for a big, easy-to-use smart TV.

    Hard to find a better TV at this price

    For the past year, had a HiSense 75" TV that has been nothing but a source of irritation, so had been looking at replacements. Among other things, its Android software took as long as a Windows desktop just to startup, constantly lost connection with my soundbar, and had built-in lag responding to its remote. Fortunately, this new TCL has none of the above issues. Immediately upon unboxing, I noticed it was relatively light and thin for its size. As I already had a heavy duty swivel mount on the wall, I was ready for mounting - which brings up the only problem I had with this TV. The mounting holes for this TV are located as far to the bottom of the set as possible. As my bracket was mounted midway up the wall, this meant that the final position of the TV would be located within inches of the ceiling. Some may prefer it this way, but my wife did not! If you're using a new bracket (there is a recommended mount in the instructions), it would not be a problem, you would simply mount the bracket in a lower position on the wall. There is another workaround, extension brackets are available to either raise or lower your bracket to a suitable position, and I'll be getting a pair to lower the TV another 6 or 8 inches. That said, it's a great set. The picture is beautifully sharp and vivid, with a myriad of controls. I prefer to keep a bright tone, while the wife prefers a more cinematic setting. My Verizon cable connection has 4K available for main sporting events, when you tune to a channel such as ESPN, a message comes on the screen "do you want to switch to 4K?", and of course I say "Yes, please!" I could reiterate the specs for the TV, which I generally take with a grain of salt, but I've watched a lot of baseball, football, auto racing, etc, and did not notice any type of artifacts or motion blur. Sharp as a tack. Remotes today are getting a little cryptic and confusing nowadays, I was glad to see this TV included Roku controls. The platform has been around quite awhile now, and not much has changed at all with their remotes. Yes, it's missing the 0-9 characters, but that makes it uncluttered and easy to work when you're in the dark. That's where you watch your TV, right? Roku got it right from the start, and didn't change the setup with new "features." Kudos to them. I have the major streaming channels - Netflix, Apple, Disney, from the start I had no burps from the Wifi setup of the set. Well, Paramount is a slug, but that's their problem, not the TV's. One more thing that pleased me was I have a brand new on the market Bose soundbar. As soon as I plugged it in, the TLC identified it, and with the proper name, Bose LS, not just a generic "receiver." Kind of gives me an indication that the software is up-to-date and responsive. I've been very happy with this new TCL that hasn't barked at me once since it's been on the wall, and I recommend giving it a look if you're in the market.

    Big-Screen Entertainment Without the Big Price

    I’ve been blessed with more than one large-screen TV over the years and one of the things that has impressed me lately is how affordable they have become. This TCL model stands out because of this. I had heard about other large-screen 4K models from TCL so I was eager to try this one. With it being 75-inches, I wanted to make sure I had the right amount of space set aside so I got a TV stand in my office and attached its stand so it would sit balanced on the stand. That was very easy, but it did require two people because of its size. So far, I have watched videos using the built-in Roku TV and played some video games on my Xbox. At first, I wasn’t sure how I would like this TV for game playing since it’s only 60Hz for a refresh rate, but the motion enhancement feature really smooths out gameplay. It’s not exactly the same as a higher refresh rate television, but it’s a decent compromise for the price point. Another feature I love is the sleek design of the TV. Since it has a bezel-less design, it really blends the screen into the surrounding environment. This was absolutely intentional to keep the viewer’s attention on the picture rather than the television itself. For me, it absolutely works. I’m very impressed with the picture quality of this TV. It’s surprisingly bright and the colors are very vibrant. Even though it’s an LED monitor, this TCL TV doesn’t have local dimming, mini-LED backlighting, or QLED technology so there is still room for improvement. All it really means is that buyers should keep their expectations of this budget-friendly TV reasonable and realistic. It’s a great picture, but it’s not meant to compete with the high-end OLEDs. All in all, this TV is a solid option. It isn’t trying to be something that it isn’t and it delivers a familiar smart TV experience along with useful modern features.

    Excellent value TV with lots of high end features

    The TCL 75" Class S55LR HDR 4K TV is a sharp‑looking set with features that genuinely make every day viewing more enjoyable. Its refresh‑rate boosters do a fantastic job during fast‑moving sports, nearly eliminating motion blur. That same boost helps action‑heavy movie scenes look smoother and more fluid. Gamers also benefit, thanks to the Game Accelerator feature, which kicks performance up a notch. And if you enable Auto Picture Mode, the TV automatically detects when you’re gaming and adjusts settings to optimize performance without you lifting a finger. Connectivity is solid across the board. You get three HDMI ports, both Wi‑Fi and Ethernet options, and Bluetooth audio support. No matter how you prefer to watch, the TV has you covered. With built‑in Roku, you can jump straight into streaming, install your favorite apps, and get everything set up quickly. The TV includes sturdy table stands if you prefer a traditional setup, and it has properly spaced mounting holes, if you want it on the wall. It feels stable and well-built when you’re lifting or positioning it. The mounting holes sit nearly flush with the back of the TV, so you don’t need any complicated spacers or special hardware to get it mounted cleanly. Overall, this TV delivers excellent value for its price. You get strong performance for sports and gaming, crisp 4K picture quality with HDR, and a near bezel‑less design that looks great in any room. It’s hard to go wrong with this one.

    A Great Deal on an 85" TV

    TCL 85" Roku TV I have the opportunity given to me to review and evaluate this amazing TCL 85" Hi-Def Color TV. First of all, it is, by far, the largest TV I have ever had in my house. It is huge. The TV is manufactured by TCL. My wife has used a TCL 55" in the living room for three years and she is quite satisfied with it, so we are not in unfamiliar territory. I have always preferred other manufacturers for my personal TV. But when I turned this TV on, I was impressed by the size, the clarity and brightness of the picture. NO MORE SQUINTING for sure. The menu to the settings were easy to navigate and the options to make changes was very easy to make. The TV included over 500 channels and most of them seemed to be free of charge. I haven't had the time to explore them all, but the TV is not going anywhere. I have to say, I have always used a Firestick for Netflix and other pay channels. The Roku is very similar but if I want or need to use a fire stick, I can plug it into an HDMI port on the back of the television. I don't know a lot about TV specifications but the 85" screen, the outstanding TV picture, the flexible channel selection ability make this a very satisfying addition to our living area. I did look up the price of this TCL TV and the price seemed very reasonable, as well. All in all, I would definitely recommend this product if I was asked.
