10 M170 FPD Monitor Installation Guide
Capacitive and Resistive Options
The monitor is available with 3M Touch System’s ClearTek® capacitive touch screen.
Capacitive is the touch screen of choice for public access applications requiring high
levels of durability and reliable performance 24 hours a day, 7 days a week.
For those applications that require flexibility of input, including gloved hand use, we
offer the M170 with a 5-wire resistive touch screen. This technology has been tested in a
laboratory environment to withstand 35 million mechanical touches without noticeable
degradation to the surface.

Native Video Resolution on a Flat Panel Display
Flat panel displays, unlike CRTs, are optimized to run at one resolution. A flat panel
display has discrete points that determine the exact location of a pixel. Each flat panel
display has an exact number of pixels associated with it. There is a one-to-one mapping
between the number of pixels and the video resolution.
A flat panel display should be used at the resolution dictated by the number of pixels on
the panel for optimum performance. For example, the M170 monitor has 1280 pixels
across the screen and 1024 lines of pixels down the screen and can accurately display this
resolution at full screen.
Options for Using Other Video Resolutions
The M170 monitor supports all standard resolutions up to their respective native
resolution for monitor setup. Refer to Table 1 for additional details. 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 1280 x 1024.
