3M™ Display M2256PW User Guide
Video Card Requirements
Using the Standard Controls for the Video Card
Supported Video Display Modes and Refresh Rates
Table 1. Applicable Display Mode and Refresh Rate
Before you connect your touch display, make sure your computer has a video card
installed that supports the native video resolution of 1680 x 1050 for the M2256PW
display. If you need information on installing a video card or video driver, refer to the
manual that came with your video card.
In addition to the standard controls on the display, each video card has several controls
that let you adjust the display settings. The software and driver for each video card is
unique. In most cases, you adjust these settings by using a program or utility provided by
the manufacturer of the video card.
For example, you can use the Windows Display Properties control panel to adjust the
desktop area (resolution), color depth, and refresh rate. Whenever you change these
settings, the image size, position, or shape may change. This behavior is normal. You can
readjust the image using the display controls described in this chapter.
For more information on adjusting the desktop area/resolution, color depth, or refresh
rate, refer to the user manual that came with your video card. If you change the
resolution, it is a good idea to calibrate your touch screen.
Your video card should support one of the display modes specified in Table 1. If you
select an unsupported video mode, the display may stop working or display
unsatisfactory picture quality.
