Buyer's Cheat Sheet: Simplifying The Jargon

Resolution
It indicates the number of vertical pixels on the screen and is what makes an HDTV so sharp. If you're buying a 40-inch or bigger set, don't settle for less than 1080p.

Contrast
This quantifies just how dark black tones appear. But ignore gimmicky terms like "dynamic contrast ratio" and judge a set by eyeballing the levels in the store.

Connectivity
If you want to use your TV as a computer, make sure it's Wi-Fi-enabled. And check the manufacturer's app store; each one has different offerings.

Inputs
You need at least three (but ideally six) HDMI ports to take advantage of the hi-def output of your components, including a Blu-ray player, a Roku, and a game system.

Refresh Rate
It's the measure of how frequently the TV updates the picture. Look no further than 60Hz—anything greater may actually make the image appear too smooth.
