The picture quality and the features of a flat screen television determine whether or not it is good. Additionally, customers may have personal preferences that influence their purchase decisions.
Contrast ratio, color range and resolution are three factors that influence picture quality. Contrast ratio refers to the difference between the brightest and the darkest parts of the screen. As television manufacturers often use different methods to measure contrast ratio, it is best examined in person. A higher contrast ratio makes the image seem more realistic and gives the image dimensionality.
Color range refers to the saturation, temperature and hue of the colors the television displays. Although most televisions allow the user to adjust these settings, not all televisions can display accurate real life colors. In fact, most manufacturers configure their televisions to display oversaturated colors, so that it stands out in a store.
Resolution is a huge factor in picture quality, but higher resolutions are not always better. If the television displays an image at a greater resolution, the image looks blurry. If it displays the image at a smaller resolution, details get lost. As such, a good television must be able to display at the resolution preference of the customer. Console gamers may prefer 1080p televisions to 4K alternatives as most games run at 1080p or lower.
The additional features a television offers also influence how good it is, although most features come down to customer preference. Whether or not a television has built-in support for 3-D movies or Netflix streaming may be important. Likewise, some televisions allow customers to surf the Internet, download games or give voice commands.
