A multi-domain vertical alignment liquid crystal display that does not require physical features on the substrate is disclosed. This isolation may be performed, for example, by providing a virtual storage adapter that is backed by one or more physical storage adapters. A shaft extends through the aperture into the first cavity and the second cavity, and a seal proximate the shaft and the plate portion seals the first cavity from the second cavity. The valve biasing springs force the valve to a location at which the valve-closing electromagnet can close the valve. Accordingly, an original LUT is read in, a parameter for selecting a grid to be downsampled is set, a table of evaluation values for selecting a grid to be downsampled is created, a grid capable of being downsampled is selected by referring to the evaluation-value table, and table data that does not contain this grid is copied. The connector allows to download software stored in the monitor, The software watches AV signals played back by the computer and furnishes data the AV signals to the monitor.
