To hold the high voltage of the monitor constant at all working conditions
is very extravagant.
A minor stabilization appears especially during the picture brightness
is changing from black to white. If the monitor has a minor stabilization,
the picture will be as shown left. Bright picture parts increase the width.
Please observe the effects on the monitor during fast changes between
bright and dark picture by the help of the test patterns.
A bad stabilization of the highvoltage leads to continuing changes
of the picture width, the so called
'pumping' of the picture.
