I need help with this problem.
I have IIYAMA VISION MASTER PRO 410 monitor (4 year). The screen is ok.
But the picture on this CRT is unstable in horizontal size . It expands and contracts itself for 1 or 2 mm for very
short time (0.5 seconds).
It happens about 20 times per hour.
What can I do? What is the problem?
Can it be a problem with voltage in this monitor or is it some other problem?
