6Installing the ID250
Matching the ResolutionFor the image output of the computer to display properly on the interactive screen, set the
computer’s resolution to the screen’s native resolution of 1024 x 768 pixels (XGA) and set the
refresh rate to between 45 Hz and 70 Hz. If you’re using an external projector, make sure the
projector can support XGA resolution.
If you need to change the display settings on the computer, you must use the mouse.
NOTE: Depending on the version, each Windows operating system may have slight variations in
the dialog box labels. The basic procedure is described below, but the specific steps vary between
operating systems.
1. Select Start > Settings > Control Panel > Display.
The Display Properties dialog box appears.
2. Press the Settings tab.
3. Move the slider to change the pixel setting to 1024 x 768.
4. Press OK.
1. Press the System Preferences icon in the Dock.
2. Press Displays.
3. On the Display tab of the Monitors dialog box, select 1024 x 768.
NOTE: Don’t set the Refresh Rate higher than 70 Hz.
4. Close the dialog box.
Adjusting the ScreenIf the interactive screen receives a signal with a horizontal frequency between 30 kHz and 56.5
kHz and a vertical frequency between 50 Hz and 70 Hz, it automatically adjusts the horizontal and
vertical position, phase and pitch settings. However, you can fine-tune the screen display settings
by using the On Screen Display Menu and the adjustment buttons on the ID250.
NOTE: Some computers and graphics cards may not allow Auto Adjust to function correctly when
you first connect the screen. If the display doesn’t fit within the LCD panel border or if some portion
of the text appears blurred, adjust the pitch and the phase. For best results, set the computer
resolution to 1024 x 768 pixels.
1. Press the Menu button to open the On Screen Display Menu.
2. Press the – and + buttons to select an option.
NOTE: You can’t use the pen, mouse or keyboard to scroll, only the ID250 buttons.
