10 M150 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 M150 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.1

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 M150 monitor has 1024 pixels across the screen and 768 lines of pixels down the screen and can accurately display this resolution at full screen.

Options for Using Other Video Resolutions

The M150 monitor supports all standard resolutions up to their respective native resolution for 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.
