    Love the quality!

    I really love this TCL 55" M8LF Series 4K UHD HDR Mini LED Smart TV with Fire TV. Right out of the box, setup was easy. I didn’t mount it, so I installed the legs instead, which required just two screws per side. Once attached, I was able to place it on a dresser without any issues. The on-screen setup was simple, and connecting it to my Amazon account was quick and convenient. I scanned a QR code, and most of the setup was completed on my phone. Overall, setup took about five minutes. I added the Spectrum TV app and was immediately connected. The app runs really fast and smoothly on this TV—much faster than on my previous one. The picture quality is stunning. Even with sunlight coming in, the colors stayed vivid, bright, and crisp. The remote feels good in the hand and works very well. When I started watching, closed captioning was turned on by default. I couldn’t immediately figure out how to turn it off, so I pressed the microphone button and said, “Closed Caption Off,” which worked perfectly. There are plenty of HDMI ports—four in total. I also played a video game on it, and the quality was spectacular, with no lag at all. Alexa is included, which is a nice bonus. I can’t say enough positive things about this TV. It’s my first TCL TV, and so far, I’m very impressed.

    This new TCL smart TV is an excellent option to have in your home and it includes all the smart and sound options that you need like Fire Tv to access all streaming apps like Netflix, Hulu , HBO max Apple TV and much more streaming apps, Alexa to control the tv with your voice, supports Dolby Atmos Sound, has 4 HDMI for game consoles, dvd players or blue ray. 4K ultra HD and gaming features like auto game mode. Easy to set up the tv, plug and easy set up with the fire tv control. The Bluetooth capability let you pair your headphones to the tv for a private listening, fast WiFi 5 performance that works great with my high speed internet connection. The tv works great with Google cast and AirPlay 2 for mobile sharing. This Tv is as good as any other named brand. The TV includes power cord, remote control batteries but does not include HDMI cables or VESA wall screws to hang on the wall ( 300mm x 300mm). I connected to my Apple Home and works fine. I recommend this TV for anyone that needs a good smart tv with an affordable price.

    Impressive Picture and Easy Setup but...

    My first experience with a TCL TV has been very positive, which is why I’m giving it four stars. The biggest strengths are the picture quality, extremely easy setup, and the fact that I was able to go from opening the box to watching content in a matter of minutes. The one major reason I’m holding back that fifth star is the physical build quality. The TV feels somewhat flimsy, particularly compared with what I would expect from a higher-end television featuring Mini-LED technology. For example, when I mounted the plastic feet on the screen (my other sets have metal feet), they are not parallel to each other. The feet feel very light, almost delicate. The setup was exceptionally quick and straightforward. I really did not need to spend much time reading the instructions. Once the TV was connected, I was watching content almost immediately. For my initial test, I selected Top Gun, since it provides plenty of opportunities to evaluate picture quality, including bright outdoor scenes, aircraft, sky, and fast-moving action. From this quick test, I could see that the picture appeared better than what I get from my other televisions. The image seemed brighter, more detailed, and more vibrant, particularly in scenes with strong contrast. While I have not yet had an opportunity to conduct a detailed side-by-side comparison using a variety of 4K HDR content, my first impression is that the Mini-LED technology is doing what it is supposed to do in terms of contrast. Since this is a Fire TV, connecting it to my Amazon account was straightforward, and that immediately brought many of the Amazon ecosystem features into the television. I didn't have to create another separate account or start from scratch with apps and services as with other hardware. My Amazon-related content and settings were readily available, and the interface provides convenient access to streaming services, apps, and other Fire TV features. For someone who already uses Amazon regularly, this integration makes the TV feel more like an extension of an existing entertainment ecosystem rather than a completely separate device that has to be configured from the ground up. The remote control is nothing particularly special, but I'm not sure how important that is anymore. It performs its basic functions adequately, and the inclusion of voice commands is arguably more useful than having a remote packed with buttons. The biggest disappointment is the physical construction. The TV looks good once it is set up, but the overall build feels somewhat lightweight and flimsy. That doesn't affect the picture quality or day-to-day operation, but it does detract from the perception of quality. Given the impressive Mini-LED picture performance, I would have preferred a more substantial-feeling chassis and construction. This is the primary reason I am giving the TV four stars rather than five. Sound quality is another area where I would describe the TCL as adequate rather than impressive. The built-in speakers are perfectly acceptable for ordinary television viewing, but the sound lacks the depth and richness that would complement the excellent picture. For movies and other content where sound is important, I think this TV would benefit significantly from a soundbar or other external audio system. That's been my experience with modern lightweight televisions. Overall, I think this is a very good television. The setup is exceptionally easy, the Fire TV/Amazon integration is convenient, and most importantly, the Mini-LED picture quality appears to be a meaningful step up from my other TVs. The build quality and average sound keep it from being a five-star product in my opinion, but the excellent picture and ease of use make it a television I am very happy to have.

    The 55M8LF can be set to turn on to the last input used instead of the Fire TV Home Screen. Go to Settings > Display & Sounds > Power Controls > Power On, then select Last Input. This should allow you to use your Apple TV device more conveniently. Thank you, TCL Customer Support
