resolution other than 1280 x 1024, the following screen appears.
Input Priority If multiple computers will be connected to the display, this
function can be used to select which computer has priority depending on the
selected Input Priority, the display will do a one time detection for available
inputs when first powered on.
For example: If the Input Priority setting is D-SUB=>D-SUB2=>DVI, then the
first priority will be given to D-SUB1 when the display turns on. If there is no
video signal on D-SUB1, then the next priority will be given to D-SUB-2, etc....
In the case of only one signal being present at the three inputs, then the display
will automatically detect and display that signal.

OSD Pivot This function is used to rotate the OSD menu, when the display is
changed from Landscape to Portrait mode.

Troubleshooting
No power
• Make sure power button (or switch) is ON.
• Make sure A/C power cord is securely connected to the LCD display.
• Plug another electrical device (like a radio) into the power outlet to verify that the outlet is
supplying proper voltage.

output port on the back of the computer. If the other end of the video cable is not attached
permanently to the LCD display, tightly secure it to the LCD display.
• Adjust brightness and contrast.
• If you are using an Macintosh older than G3, you need a Macintosh adapter.
Wrong or abnormal colors
• If any colors (red, green, or blue) are missing, check the video cable to make sure it is
securely connected. Loose or broken pins in the cable connector could cause an improper
connection.
• Connect the LCD display to another computer.
• If you have an older graphics card, contact ViewSonic for a non-DDC adapter.
Control buttons do not work
• Press only one button at a time.
