C Native Resolution
The native resolution of a monitor is the resolution level at which the LCD panel is designed to
perform best. The native resolution is 1024 x 768 for the 15 inch size. In almost all cases, screen
images look best when viewed at their native resolution. You can lower the resolution setting of a
monitor but not increase it.
Input Video

1024 x 768 (XGA)
The native resolution of an LCD is the actual number of pixels horizontally in the LCD by the number
of pixels vertically in the LCD. LCD resolution is usually represented by the following symbols:
VGA
SVGA
XGA
SXGA
UXGA
As an example, a SVGA resolution LCD panel has 800 pixels horizontally by 600 pixels vertically.
Input video is also represented by the same terms. XGA input video has a format of 1024 pixels
horizontally by 768 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.
