Wavy Monitor

I do not want to admit it but my Monitor is starting to wave.


Is it on it's way to bieng toast??

My first question is when did your monitor grow a hand?

Second, have you stuck any power hungry devices, power lines, or speakers by it lately?

Try changing the refresh rate to something higher (if it can go higher).

All right I changed it from 60 Hertz to 120Hertz. The brightness went down. And the proportions changed.
The Friendly Waving went stop as I was writing the first post, but maybe this will take care of it.
A couple of questions, just for curiosity's sake.
What does the referesh rate have to do with the proportions?
Is the refreash rate how often it communicates with the computer?

I agree with Whir, nearby electrical motors and speakers can cause monitors to display screwy images...if this is not the problem, then yes it is on its way to the monitor graveyard. Repairable, but costly..the cause will be weak capacitors in the power supply and not filtering the AC component out of the rectified DC..this will cause a wavy effect due to the retrace of the horizontal lines (too fast to be seen by the human eye) that must be pure DC..if any AC is in this circuit, the retrace will not be linear, and can contain an irregular retrace set of lines...which will affect any image that is then presented to the phosphor for display. (phosphor is the old CRT technology).
