Options for Using Other Video Resolutions
The MicroTouch 13.8" and 15.0" Profile and ChassisTouch monitors
have a 1024 x 768 (XGA) flat-panel display.
If you use a resolution that is less than
the number of pixels resident on the
flat-panel display, the monitor will show
the image using only the total number of
pixels generated by the source. For
example, the monitor uses only 800
pixels across and 600 lines of pixels
down the screen when displaying an
SVGA (800 x 600) resolution. The
remaining pixels are not used. In this
case, the monitor preserves the image
quality, but does not use the entire screen. You will see a high-quality
image centered in the display and surrounded by a black border of
unused pixels.
You can use the monitor’s on-screen controls to expand the image to
fill the entire screen. To fill a 1024 x 768 flat-panel, the monitor
expands an 800 x 600 resolution by 1.25 and a 640 x 480 resolution
by 1.6. In both cases, the monitor spreads fewer pixels of information
across a larger number of pixels. Although this technique produces an
image that fills the entire screen, the image will be distorted. The
pixels will take on a broader or fuzzier appearance.
The MicroTouch 13.8" and 15.0" FPD monitors support the 800 x 600
(SVGA) and 640 x 480 (VGA) resolutions primarily for compatibility
and monitor setup. Many video cards initially display a screen image
at the SVGA or VGA resolution. By supporting these resolutions, the
monitor can display the desktop controls that let you change to the
optimal resolution of 1024 x 768.
