TCL 55 Inch Class 4 Series 4K Smart TV Review

View on Amazon

TCL is a popular brand name but it doesn’t name its all the TVs are good. Some of them are good and some of them are not very good. What I see is that those TCL TVs, which are not good, they sell either. However, it loses customers by selling those low-quality TVs.

No I come to the point. The point is to give you information on this TCL 55-Inch Class 4 Series TV. Please know that the information I supply here is from various users’ reviews. However, I use my creativity to consider only those genuine reviews given by the actual customers who have used the product. One thing I see is that Amazon has lots of fake product reviews. These reviews are both positive and negative. I think the positive reviews are the self-promotion by the manufacturer, and the negative reviews are from its competitors.

First of all, please let me give an overview on the key features. As per the product description, it uses a standard LED display technology, and has a wide range of built-in apps such as Netflix, Prime Video, You Tube, Disney Plus and more. It is an ultra HD 4K TV with HDR (high dynamic range). It has a built-in Google Assistant feature, which is a voice control feature that facilitates to use your voice instead of using the buttons.

Second, it has the built-in Chromecast. Therefore, you will be able to watch your favorite content on the big screen by casting them from your Android or iOS devices. This is a good feature as it is a great way to access a portable entertainment source. Read more…
