The difference between good and poor picture quality can be seen by anybody. However, it is not very easy to understand the technical issues that make a picture look good. One very important element of picture quality is contrast ratio. Other aspects are the color saturation and color accuracy, and resolution is also very important.

Contrast ratio is the ratio between the darkest and the brightest color your HDTV can produce. Obviously, the higher the contrast ratio is, the better your system is. Low contrast ratio means washed out pictures, dull images and lost details. In the recent years contrast ratio had been greatly improved. Best contrast ratios have a price premium, but technology is getting cheaper. At this time, even the low-end HDTV's have decent contrast ratios.

Black levels are also very important for good picture quality. Good black levels mean you see absolute blacks, not greyish blacks. Poor black levels can be especially annoying in dim light conditions, because this is when your eyes are very sensitive about blacks. Lot of people achieve absolute black by setting the black levels too low: by doing this you may have absolute blacks, but black shadow details will be lost. Another important aspect of picture quality are the high white levels.

High white levels are good because they help images become vivid and lively. White levels also make daytime viewing more pleasant. Again, it is not a good idea to set white levels too high, because bright highlights and details can be lost.

Color temperature, saturation and accuracy are also important elements of picture quality. The natural light temperature is 6500K, and this is the standard for setting the color temperature. Color temperature is below this will be yellowish or reddish, if above, will be bluish. Setting color temperature correctly is important because this can influence every color on your screen.

The color saturation of your HDTV can be adjusted by using the color patterns that come with calibrations discs or TV channels. Color accuracy is a function of how your system decodes image data. Color accuracy is a wide topic: if you don't want to be a pro, it is enough for you to know that the color reproduction is accurate when the color encoding used in film production match the decoders of your HDTV.

Greyscale and display characteristic also affect the color reproduction of your HDTV, but again this is above the beginners knowledge about image calibration. You can choose to learn about this, or you can hire a specialist to do it for you.

There are 5 times more pixels in the latest HD resolution than in the Standard Definition. The difference is astonishing: with HD, you can notice details you never knew that existed. Today, 1080 capable HDTVs represent the best money can buy.

Another notion related to resolution is percieved sharpness. This is very similar to the concept of edge contrast used in photography, and it basically means that users have the choice to make the image borders crispier. This gives the sensation of better image quality with the same resolution.
