NATIVE RESOLUTION
The native resolution of a monitor is the resolution level at which the LCD panel is designed
to perform best. For the Elo LCD touchmonitor, the native resolution is 1280 x 1024 for the
SXGA-19 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.

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 640 X 480
SVGA 800 X 600
XGA
1024 X 768
SXGA
1280 X 1024
UXGA
1600 X 1200
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
