Symptoms related to personal computer monitor
Symptom
$ Nothing at all appears on the
monitor screen or the "NO SIGNAL"
or other warning display appears.
$ The display keeps running off the
monitor screen.
$ The display on the monitor screen
is subject to wave-like noise,
distortion or jitter resulting in
horizontal or vertical wobbling.
Suggested remedial action
O First, check whether the monitor is a PC/AT compatible monitor.
O When nothing at all appears, check the supply voltage, connecting
cables (for disconnections) and monitor unit settings.
O Some monitors have their own self-diagnosis functions. If you feel
that the monitor unit is responsible for the trouble, refer to the manual
accompanying the monitor, and check the adjustment and test
methods.
O If you still cannot trace the cause of the problem, try replacing the
troubled monitor with a monitor whose operation is trouble-free if
such a monitor is at hand.
O Check the monitor's resolution setting.
This product's default resolution setting is 1152a870, and its default
refresh rate setting is 75 Hz.
These settings may not display properly on some monitors. Refer to
the manual accompanying the monitor, and check its available
resolution settings.
O If you still cannot trace the cause of the problem, refer to the above
symptom (Nothing at all appears on the monitor screen or the "NO
SIGNAL" or other warning display appears), and check whether the
monitor is to blame for the problem.
O If the monitor is determined by its self-diagnosis function to be
trouble-free, review the monitor's installation location.
Trouble may be caused in the monitor display by the adverse affects
of magnetic fields generated by other devices (such as another
display, fluorescent light or transformer). In a case like this, turn off
the monitor, distance the monitor from the other devices, and turn the
power back on. (The picture distortion, etc. may remain if the monitor
is moved while the power is still supplied.)
