Video Card Requirements
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
Using the Standard Controls for the 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.
Supported Video Display Modes and Refresh Rates
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.
