Contrast ratio is subjective

While shopping for new HDTVs this holiday season, take into account the contrast ratio of the television. While it is possible for two televisions to have identical contrast ratios, their pictures may look different because there is not a universal standard in the United States. Without an industry standard, contrast ratio is subjective by each manufacturer. Contrast ratio, which is one of the specifications of HDTVs, deals with the amount of light your television emits.

The contrast ratio, as one may expect, encompasses the brightness and darkness of images. In essence, a contrast ratio determines how dark the dark colors appear and how bright lighter colors appear. For example, a dark cave may appear black on a Samsung 65 inch TV, whereas you can see the textures and scripture on a Panasonic Viera plasma HDTV. The higher a contrast ratio is, the more detail it can project for dark colors. Without getting too technical, contrast ratio measures the difference in light from dark to bright colors.

Often times, you will find a contrast ratio listed on the product brochure or display. For example, the KDL40EX400 contrast ratio is 140,000 : 1, which means white or bright colors are 140,000 more brighter than darker colors. Most consumers desire a television that has a high contrast ratio, because you can see more detail while watching movies on a LG Blu-ray player. To further confuse viewers, manufacturers measure the contrast ratio using static and dynamic formulas. Static contrast ratios are more accurate, whereas dynamic contrasts give the manufacturer leeway when reporting the figures.

Contrast ratios are manufacturer-dependent, because there is not a universal scale of measurement. It is pointless to compare a Sony KDL40EX400 contrast ratio to a Toshiba TV, because both manufacturers employ different measuring techniques. A 140,000 : 1 contrast ratio for Sony might equate a 30,000 : 1 contrast ratio for Toshiba. It is useful to compare ratios when choosing between specific models in a manufacturer’s product lineup. Furthermore, do not compare static ratios to dynamic ratios, and vice versa.

In the end, contrast ratio is a subjective unit of measurement, as it boils down to your personal preferences. Other factors to consider when purchasing HDTVs this holiday season include resolution, size, connectivity, ports, and weight. Choose televisions that offer 1080p resolution for a crystal-clear image, and opt for 120 Hz if you watch a lot of sports. Lastly, choose a television that is appropriate for the setting, as the viewing angles and positioning of your HDTV impacts your user experience.
