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 
Multi-touch 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.
