Besides the brand factor, there are a lot of things to look for before buying a 42-inch Smart TV. First is the connectivity. It should have at least 2 USB and HDMI ports so that you can effortlessly connect a portable hard drive or your tablet to the TV. Next is the sound quality, which can let you enjoy your favorite TV shows and movies without using an external speaker. Lastly, you should check the warranty and customer support. You can check all these features by shopping online at the best stores like Amazon, Flipkart, Tata Cliq, and Croma. This is the easiest and fastest way to compare the features and prices of the best and the latest 42-inch Smart TVs so that you can buy the best Smart TV at the lowest price.
