As an example, a SXGA resolution LCD panel has 1280 pixels horizontally by 1024
pixels vertically. Input video is also represented by the same terms. SXGA input video has a
format of 1280 pixels horizontally by 1024 pixels vertically. When the input pixels contained
in the video input format match the native resolution of the panel, there is a one to one
correspondence of mapping of input video pixels to LCD pixels. As an example, the pixel in
column 45 and row 26 of the input video is in column 45 and row 26 of the LCD. For the case
when the input video is at a lower resolution than the native resolution of the LCD, the direct
correspondence between the video pixels and the LCD pixels is lost. The LCD controller can
compute the correspondence between video pixels and LCD pixels using algorithms contained
on its controller. The accuracy of the algorithms determines the fidelity of conversion of video
pixels to LCD pixels. Poor fidelity conversion can result in artifacts in the LCD displayed
image such as varying width characters.

• To avoid risk of electric shock, do not disassemble the brick supply or display unit cabinet.
The unit is not user serviceable. Remember to unplug the display unit from the power outlet
before cleaning.
• Do not use alcohol (methyl, ethyl or isopropyl) or any strong dissolvent. Do not use thinner
or benzene, abrasive cleaners or compressed air.
• To clean the display unit cabinet, use a cloth lightly dampened with a mild detergent.
• Avoid getting liquids inside your touch monitor. If liquid does get inside, have a qualified
