5 Pixel errors & Supported Operating modes Due to the technology used to build LCD-modules, pixel errors are unavoidable. A standard 1024 x 768 display has 786,432 pixels. Each pixel consists of three subpixels (red, green and blue), which means there are 2,359,296 subpixels. This is also the number of driver transistors needed. If you wanted to make sure that every transistor on an LCD display is working properly, i.e. that there are no pixel failures, an enormous amount of waste would be produced and the price would also be exorbitant. Error rates have to be specified in order to produce LCD panels for a fair price. These error rates are given to us by the panel manufacturers.

For an optimal picture it is recommended to choose a mode listed in the table. • You have 12 available modes compatible with Windows. . • It can happen that the image is disrupted. This can occur as a result of a signal frequency from the VGA card, which does not correspond with the usual standard. This is not, however, an error. You can improve this situation by altering an automatic setting or by manually changing the phase setting and the pixel frequency from the "Geometry" menu. • If you switch off the monitor, interference lines can occur on your screen. But do not be concerned about this, as it is normal. • To extend the service life of the product, we recommend that you use your computer's power management function. 10
