Solution
• Check that your computer is turned on.
• Verify that you are using the video
cable that came with the SMART
Podium ID422w.
• Check that the SMART Podium
ID422w video cable is fully connected.
• Turn off both your computer and the
SMART Podium ID422w pen display.
• Check the video cable and any video
adapters for bent or broken connector
pins. Then properly connect the video
cable and any necessary adapters.
• The input signal frequency is
incorrectly set or not compatible with
the SMART Podium ID422w. Set the
refresh rate (vertical frequency)
between 50 and 75 Hz. If your video
card driver supports adjustment of the
horizontal frequency, make sure it is
set to some value between 30 and 80
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 (1920 x
1080, maximum).
• The refresh rate is set too high (76 Hz
maximum).
• Set the display properties to detect
plug and play monitors.
• The maximum refresh rate is 76 Hz.
Set the refresh rate (vertical frequency)
to some value between 56 and 76 Hz.
• Do not extend the video cable. Do not
use an input selector switch box.
• Use a screen saver or other power
management feature.
