Don't invest in a 3-D TV without these buying guidelines.
Step 1: Decide between plasma and LCD Decide between plasma, LCD, and LED-backlit LCD 3-D TVs. Plasma has less motion blur and provides better viewing for people not sitting directly in front of the TV. LCD typically has better resolution, which makes a particular difference if the TV is less than 43 inches. LED-backlit LCD TVs are brighter and have better contrast.
TIP: Anything you can watch on a regular TV you can watch on a 3-D set.
Step 2: Pick a refresh rate If you decide to go with an LCD 3-D TV, evaluate the refresh rates: 120 Hz, 240 Hz, and 480 Hz. 120 Hz is sufficient for most people.
TIP: Despite the number, 480 Hz is not twice as fast as 240 Hz.
Step 3: Decide between 3-D and "3-D-ready" Decide between buying a 3-D TV that includes the necessary infrared emitter that sends signals to the compatible 3-D glasses you must wear to watch, or a "3-D-ready" set that may require you to buy 3-D hardware separately.
Step 4: Go big or go home Buy the largest screen you can afford. When it comes to choosing a 3-D TV, bigger is definitely better.
FACT: Television was first introduced to the public at the 1939 World's Fair in New York.
