    Perfect TV for Small Family Room

    Upgraded this 40" tv from an over 10 year old 32" Sony flat screen tv (that still works to this day). I have a small family room space and thought it would be too big, but it's perfect. TV is thinner than I expected and was light enough to transport by myself (way lighter than I thought it'll be). Putting it together, connecting to the internet (for the smart tv features), and hooking it to my cable box (I'm still a cable box guy lol) were simple. With this tv, you can connect the cables in the back sideways so can flush the tv close to the wall (or for easier mounting). Picture and display are an easy upgrade and improvement from what I had, which I can primarily vouch for as my comparison. It still seems to be comparable to other models from what I see in the stores, if you are to stream 4K or high def videos. I do have to sometimes have to adjust the screen resolution for my cable box connection periodically (not sure if that's due to my cable provider, cable box, or this tv, but in time, I guess I'll find out). If the broadcast is in high def, the display looks good and is vibrant. I mainly watch sports, so it satisfies my needs. Connection to my Bose soundbar works fine (though sometimes takes a minute or two to connect at startup here and there). I've still yet to figure out the Roku and smart tv streaming features, but the interface as well as the tv adjustment settings are easy to navigate and super quick for selection with the provided remote. The tv was on sale so for price I paid, it was worth it. Hope it lasts as long as my old Sony. I usually would steer towards high end name brands with long standing reputation, but I read up on TCL and seems like they've been around awhile and have a lot of good products out now. Only had this for about a week, but at this moment, seems like a well paid purchase and upgrade.

    Excellent Performance

    This 40" TCL TV meets my expectations and replaces one of the 2 identical 40" Visio TVs that was situated above the large Samsung TV in my home theater. Having 2 different remotes for the upper TVs makes it much easier to control the inputs and the ROKU system on this TV is easy to use. The only issue I have is that it is not included in TCLs registration system yet and I am awaiting resolution from TCLs customer service.

    I Like The Roku Platform

    I purchased two of these because of the price. The size was decent for the price and it’s the Roku platform which I have on all my TVs. These are also TCL brand which I’ve had before and have been satisfied with. The picture is clear and bright. The only downside (and this is for any flatscreen) is the sound quality isn’t the best with the built in speakers.

    Banger for the price

    I own several TCL televisions of different sizes. TCL makes quality televisions at an exceptional price in my opinion. So when I got this television, I expected the same quality and experience. Although 1 thing which was new to me was the Roku interface. I have not used this before but was pleasantly surprised at how easy and flawless it was. The Roku remote had the 4 quick start button that I used the most and I really liked that the volume button was on the side. It was a natural place I put my hands but I can see that accidental touches might be a problem. The 40" size is perfect for my use. I put mine in my garage to use with my home gym. The 1080p resolution is more than adequate for a screen this size, especially for everyday TV watching and streaming movies Most videos I've watched has been crisp and vibrant and I have no complaints. The speakers are adequate but it's not going to blow you away. I will probably add some type of external speakers because I like to stream music. videos while working out. But 1 of things that really stood out for me was just how slim and light this television is, it felt like it should cost so much more. This really is a good valued tv, you get so much for the money.

    TCL= affordable and great quality

    I can't believe how lightweight this TV is! I honestly thought there was nothing inside the box for a minute. This TV is replacing a very old, heavy flat screen that took an arm and a leg to hang, so when it came time to mount this one on the wall, it was super easy. The TCL QLED went into a small room, so 40 inches was the perfect size. Setting up the TV was very straightforward Roku TV offers an impressive amount of free content, and it came preloaded with all my favorite streaming apps. Logging into each app was a breeze using the on-screen QR codes. The QLED panel provides amazing picture quality with crystal clear images. Even though this TV is 1080p rather than 4K, it still delivers great quality for the price. The sound quality is decent, at max volume, it can sound a bit like a cheap speaker , but you can easily upgrade it with an external speaker or soundbar if needed. I also love the compact Roku remote, and if you ever misplace it, replacements are inexpensive and easy to find anywhere. Great TV at a wonderful price
