What to look for in a 40-inch smart TV
Screen Resolution- Not all smart TV screens are created equal. You can find models with 720p, 1080p full HD, and 4K UHD panels. What you should choose for your home depends on the kind of movies and shows you plan on streaming and watching. Regular and Blu-Ray DVDs? Choose a 1080p full HD television. Plan on streaming UHD content and buying a UHD DVD player? A 4K UHD model is the right choice for you.
Voice Controls- Voice commands are quickly becoming the new standard when it comes to home televisions. Many smart TVs now have some form of hands-free voice controls integrated into their remote controls or are compatible with devices like Amazon Echo and Google Home speakers. Some even connect to your smartphone so you can use Siri or Cortana.
Streaming Platform- Some smart TVs have the Roku platform built in, so you get access to thousands of music and movie streaming apps all in one place without the need for extra equipment. Others have their own proprietary hub menus for quick access to apps.
