The colors available in the palette itself may be fixed by the hardware or modifiable by software.
With the relatively low color depth, the stored value is typically a number representing the index into a color map or palette (a form of vector quantization). 8 and smaller use an adaptive palette so quality may be better than some systems can provide. Same image on five different color depths, showing resulting (compressed) file sizes.The number of bits of resolved intensity in a color channel is also known as radiometric resolution, especially in the context of satellite images. The definition of both color precision and gamut is accomplished with a color encoding specification which assigns a digital code value to a location in a color space. Modern standards tend to use bits per component, but historical lower-depth systems used bits per pixel more often.Ĭolor depth is only one aspect of color representation, expressing the precision with which the amount of each primary can be expressed the other aspect is how broad a range of colors can be expressed (the gamut). When referring to a color component, the concept can be defined as bits per component, bits per channel, bits per color (all three abbreviated bpc), and also bits per pixel component, bits per color channel or bits per sample (bps). When referring to a pixel, the concept can be defined as bits per pixel (bpp). On a monitor with over 12 million pixels (Wide QXGA+, 2560x1600 pixels), for example, LG's pixel policy says that 12 bright or dark sub-pixels is the maximum you have to tolerate.Color depth or colour depth (see spelling differences), also known as bit depth, is either the number of bits used to indicate the color of a single pixel, or the number of bits used for each color component of a single pixel. However, this is not considered a defect unless the number of bright and dark subpixels exceeds the maximum allowable threshold (.) The customer may notice the bright or dark spots if the film of the liquid crystal does not perform as expected while customers uses the LCD monitor. Note that most manufacturers define a maximum number of allowable bad pixels for specific resolutions, and the warranty won't apply until your monitor crosses that threshold.īright or dark sub-pixels can occur during the production of the LCD Monitor panel but does not affect the LCD Monitor functionality. The manufacturer or the marketplace where you purchased the monitor might cover dead pixels. If the defect affects more than a single pixel, however, or just bothers you a lot, you can always replace your monitor.įirst, check the warranty. One ugly pixel won't break your screen, and eventually, you'll forget about it. When all attempts to revive your bad pixel fail, the next best thing you can do is to make peace with it.
