What to Consider When Buying a 40-inch Smart TV
Resolution and HDR
Resolution refers to the general sharpness and clarity of the picture. Currently, 8K is the newest resolution available in the market, but it will take a while before content will be made available in this resolution. 4K (Ultra HD) is a realistic standard, and 1080p ((Full HD) is a pretty decent resolution too.

Ports
Do you only need HDMI, or will you also be needing scart, coax, and other ports? And how many of each do you need? Ultimately, this is determined depending on what devices you plan to connect to your TV. Besides the types of ports and the number, you also need to consider which part of the TV they’re on. You would want them to be easily accessible, as unmounting the TV just to have access to the ports is not practical.
Smart Software
What smart software does the TV run? Does it come with an app store where you can easily download additional apps from? How does the interface feel?
Speakers

You wouldn’t want a tinny sound when watching a movie or playing a game. Some smart TV brands partner with audio engineering companies and develop their own sound system. It’s important to test this and read up on the latest TV audio trends too.
