    • Nice 4k ROKU TV for starters in 4K
OK, first off, please read this: This is a ROKU TV system. Yes you can use it with cable TV or with an Over The Air antenna, but it is still a Roku. And let me explain one part about Roku. In order to use Roku, you MUST set up an account, and the reason for a payment method on file is so that if you wish to enable a Netflix or Hulu subscription (for example), the payment is automatic. The only time you pay ANYTHING is when you either take a subscription or buy a rental. But at no time are you charged any fees. We cut the cable cord two years ago with Roku Express+ 4K on our HD TV sets, and at that time, when I created the account, I did put my card on file, and have NEVER once been charged without my knowledge, since I DID set the account up to require a PIN. And we only rented one movie in all that time. No extra fees whatsoever. Now, let's move on to the TV itself. Country of Manufacture is China. In the box you get: TV Two TV Stand legs with screws 6 foot Power Cord Remote Control with two batteries. Remote is a Roku remote that is pre-paired to the TV. Even easier than the Roku 4K Express+ Quick Start guide with warranty photo registration code Setup was quick and easy. I attached the legs, put batteries into the remote, plugged the TV in and went through the setup process. In about 15 minutes, I was watching OUR channels that we had selected, and seeing things from a whole new perspective 4K is an awesome way to start and yes, this is a starter system. Colors will brilliant and vibrant and life-like, and the set will automatically adjust to your source resolution. Some of the things I like, is that I can attach an Ethernet cord instead of using wireless and ensure a constant streaming experience, although I have tweaked our wi-fi network enough that there is no buffering. There are THREE HDMI input ports for whatever you wish to connect to the TV as well as an HDMI ARC port if you have a sound bar setup. You also have a USB port for movies. songs and photos, an Ethernet port, a coaxial cable port for either an External Antenna or Cable TV Feed, an AV In adapter port (adapter NOT included) for older video equipment and headphone out for either Headphones or external audio equipment. Unit comes with a 1 year warranty and you can opt to buy additional protection if you so choose. The set will upscale 1080P sources to near 4K UHD and there is also a special Roku Channel for 4K to get you started. The set weighs 26 pounds, so if you wish to mount it to a wall mount you will want a VESA 200x300 capable mount. Those are easy enough to find here on Amazon. VESA 200x300 mount will use (4) M6x12mm screws if you already have a wall mount. Is this a Super high end 8K or QLED or OLED TV? NO. But if you are looking to start out into 4K with something that is affordable and easy to set up, then the Class-4 series will be a good choice for you. 5 stars and two thumbs up, as well as a recommended buy from us.

    • Best TV on the Market for the Price
I was looking to buy an affordable ~50" 4K TV for my new home, and I bought this one for my living room and a Vizio V series for my office/man cave. Well, the TCL was the clear winner of the two to the extend that I actually returned the Vizio (lots of issues with software and speakers) and bought another TCL to replace it (so I have a 50" and 43" of this model now). Biggest pluses: - Roku software is top-notch, reliable, and intuitive/good UI. Yes, you need to sign-up for a (free) account if you don't already have one, but the plus there is when you buy another one, it'll auto-install the apps you already use - Every video app you can imagine is supported (MLB.TV, Netflix, HBO Max, and Hulu are my most used) - Sound is pretty good, although I did buy a sound bar to take advantage of eARC port, which was also super-easy to setup once and forget about (soundbar used automatically -- volume controlled from TV remote) - I know some people have complained about the remote, but I actually quite like it once you get used to it, outside of two caveats listed below -- the sound controls on the side of the remote is very intuitive and I way prefer it to the way most remotes do it - EASY to connect to AirPlay or Windows Wireless Remote Display, which is key for me - I like customization of the input names (and icons) so you don't need to remember that Input 2 is Cable Box while Input 3 is Playstation etc - Good HRD for gaming from what I could tell, but I'll admit I'm not a big expert The only downsides I have, which I think are FINE considering the low price of these models: - The remote doesn't light-up ever, and since I like to watch movies with the light down it can make me fumble to find the pause button when needed - No way to change from one input to another without going to the homescreen (that I can tell), which makes flipping between a game on Live TV (via Cable Box input) to my game on pause (on PS4 Pro input) take a bit longer -- those couple of seconds make a difference when you're watching March Madness and the commercial breaks are short Overall, I can't imagine you'll find a better TV without going up an order-of-magnitude on price. TCL is my new go-to brand for screens. ... show more

    • BLACK SCREEN SOLUTION
BLACK SCREEN: The quality of the screen is very good and the sound is all right. I love the simple setup and the price you pay for the quality of the image. About a month ago, MY SCREEN WENT BLACK. I tried using Roku customer support, unplugging it for a while, doing other hard resets and looking up how to fix the issue with a manufacturer. The sound was basically working, but the screen was black. I then noticed that when I went back and searched for the same product, the reviews with lower stars had the same issue. They had to get a new TV. I found the small reset button next to the HDMI port and I used a paper clip to press it. It seemed like it was going to work at first, but then it went back to black again. I left to the store and came back over later, about to throw the TV away because it was being a waste of space considering it didn’t work. I decided to try and turn it on again after hours of having pressed the reset button and all of a sudden, it had finally hard reset. PLEASE DO NOT THROW THE TELEVISION AWAY AND I HOPE PEOPLE FIND THIS REVIEW. ... show more
