Your Options for 40- to 49-inch Plasma TVs

Some people choose plasma TVs for their entertainment setup in dark rooms because they are known for brightness and high-contrast ratios. Several brand manufacturers that offer 40- to 49-inch plasma screen TVs include LG, Sony, Samsung, and Panasonic.

What is a plasma TV?

A plasma TV features a plasma display panel (PDP). Plasma is a collection of small cells that have electrically charged ionized gases. This type of display is most frequently used for screens 30 inches and larger. Plasma displays are bright and have a wide color gamut. The brightness is 1,000 lux or higher. The screens are usually made of glass. Contrast ratios can be as high as 4,000:1. Because of subfield drive technology, plasma electronics have little to no motion lag.

What are possible features of these TVs?

Many of these televisions have virtual surround sound, which is an audio system that creates the perception of more sounds than actuality. Some offer sharp pictures through higher resolution known as high-definition (HD). Some have headphone jacks, so you can listen to the audio without disturbing others in the room. Other possible features are the widescreen mode, closed captions, and sleep timers. TVs equipped with widescreen mode let you choose the aspect ratio. Closed captions transcribe the audio as subtitles in real time. Some support multiple languages like Spanish and French in addition to English.

  • Resolutions of 853x480, 1,366x768, and 1,920x1,080
  • Aspect ratios of 14:9, 4:3, and 16:9

How do you find the right plasma TV?

When you have an understanding of the terminology, you can find the right plasma TV. Picture quality is influenced by upscaling and downscaling algorithms and the video scaling processor. Some plasma TVs are also labeled as HD, which has to do with the TV screen's resolution. Understand that there is more than one contrast ratio test. Two of the most widely used tests are the ANSI standard and the full-on/full-off test.

You already know the display size you're looking for, so the next factors to clarify are the minimum resolution you're willing to consider, aspect ratio, contrast ratio, and sound system. Do you want built-in speakers or will you hook up a sound bar? Are there any extra features important to you like 3D capability, Wi-Fi connectivity, headphone jacks, or closed captions? Answering these questions will help you find the right model.
