Screen Size
Perhaps the most important choice you’re going to make with a new TV is the size of the screen. TV screens are measured diagonally, and they range in size from fewer than 20 inches to more than 80 inches

Choose Between HD and Ultra HD
These terms refer to the TV’s native resolution. A regular high-definition (HD) set is also a called a 1080p model, as its screen resolution is 1920 x 1080.

Decide Whether You Want a Smart TV
Around 60 percent of the TVs sold these days are now smart TVs, according to market research firm Quixel Research. But if you're considering a more basic TV, or already have a TV that lacks smarts, you can easily add Internet capability using a separate streaming media player, such as an Amazon Fire TV, Apple TV, or Roku player. Prices start as low as $35 for a smaller stick-styled player

Check the Viewing Angle
Despite many improvements, most LCDs still have a fairly significant shortcoming: limited viewing angles. That means the picture looks its best only from a fairly narrow sweet spot right in front of the screen.

Make the Right Connections
Don't forget to consider a TV's connections before you buy. You'll want to ensure that it has the right type of inputs and outputs to support all of your A/V gear.
