How to Compare 42 Inch Plasmas

by Art Corvelay
  • Overview

    Televisions with 42-inch screens are a very popular for HDTV buyers. Although plasma TVs are becoming increasingly affordable, purchasing a 42-inch plasma is still not a small investment. Therefore, it is important to be an informed buyer. Even though all 42-inch plasmas have the capability to display high-definition video, there are some distinguishing features that you should look for when purchasing a plasma.
    Plasma TVs are not all created equal.
  • Step 1

    Look for the number of HDMI inputs on the 42-inch plasma TVs you are comparing. All 42-inch plasmas have HDMI inputs, but the more inputs, the better. HDMI produces extremely high quality video and audio because it is a digital connection. Therefore, a TV with more HDMI inputs allows you to connect more devices like a Blu-Ray player, stereo system, and cable or satellite receiver.
  • Step 2

    Note all of the various other video input options that come with the TV. For example, some plasmas come with direct DVI inputs, which allows you to connect your computer to your TV without an adapter. Other plasmas, however, don't include any special video input connections.
  • Step 3

    Compare the resolutions of each 42-inch plasma. Resolution is the number of pixels that can fit on the screen. A higher resolution typically produces a better picture. The most common resolutions for a 42-inch plasma are 1080 or 720. However, some argue that there is no difference 1080 and 720 on TVs that are smaller than 50 inches in size, depending on how far away you sit from your TV.
  • Step 4

    Check the plasma TVs refresh rate, which is measured in hertz. The refresh rate refers to the frequency with which the image is being updated on your TV. A higher refresh rate is considered better and will produce a less streaky picture with fast-moving images like sporting events. Typical refresh rates include 60 Hz, 120 Hz, and 240 Hz.
  • Step 5

    Find out what comes with the TV. Some manufacturers or stores provide a TV stand, while others don't. Further, some even provide wall mounting brackets and complimentary installation, while others charge for both the brackets and the installation.
  • Step 6

    Compare the price of each plasma. This is an obvious point of comparison, but still a very important one. Set a budget and stick to it.
