to the documentation that came with your operating system or applications.
GENERAL DISPLAY PROBLEMS

cable is securely plugged into Cintiq’s power receptacle. Check that
Cintiq’s power switch is turned on.

screen.
• Your computer may be in a power management mode. Touch the
pen tip to the Cintiq display screen, move the mouse, or depress any
key on your keyboard.
• Turn off both your computer and the Cintiq pen display, and check
the video cable for bent or broken connector pins. Then properly

• The input signal frequency is incorrectly set or not compatible with
Cintiq. Set the refresh rate (vertical frequency) to 60 Hz (or between
56 and 85 Hz if you are using a resolution of less than 1600 x 1200
pixels). If your video card driver supports adjustment of the
horizontal frequency, make sure it is set to some value between 31
and 92 kHz. On a single monitor system you will need to connect a
different display to change the refresh rate.
• The resolution is set too high (1600 x 1200, maximum).
• Set the display properties to detect plug and play monitors.
The image appears multiple times
on the display.
• Do not extend the video cable. Do not use an input selector
switch box.
When a still image is displayed for
a long period of time without
refreshing the screen, an after-
image remains for a short period of
time.
• Use a screen saver or other power management feature.
