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 brightest and darkest color a HDTV can produce. The better your system is, the higher contrast ratio it can produce. If your system has low contrast ratio, you will experience dull and washed out images, and fine details will be lost. The good news is that there were great improvements in contrast ratio, and even cheap HDTVs have enjoyable contrast ratios at this time.

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 make images vivid and lively, and it is also makes daytime viewing more pleasant. Just as with the blacks, it is not a good idea to set the white levels too high, because 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.

Color saturation can be relatively easily adjusted by using the color patterns that come with calibrations discs or TV channels. Color accuracy depends on how your HDTV decodes the image data. These are pretty complicated issues. You may want to read more about this elsewhere, but if you only want to stay at beginner-level, it is enough for you to know that the decoders of your system should match the color encoding used in film production.

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.

The best HD resolutions today have 5 times more pixels than the old Standard Definition. The old format can not be compared to HD images: today, every detail of the image can be seen sharply. If you want to have the best technology available today, buy a 1080 capable HDTV.

The term of percieved sharpness relates to resolution. It means users can sharpen artificially the image without modifying the resolution by creating a crisp edge along the border of the image. This also gives the impression of better image quality.
