When I hold my sleeve up to my mouth and make a farting sound(i was bored) the screen seems to flicker and looks like it is on 50Hz refresh rate(it is on 85) but everything else around it is perfectly normal, The logos on the monitor, my cd's and the book in front of me do not seem to change but the monitor can be seen to flicker. It works in bothe the periphial and striaght vision.

It also seems to jerk up and down with the intensity based on how hard I blow. When I blow my hardest, it jerks about 3/4 of the size of one line, making text unreadable. What is going on?

but why does the monitor flicker when everything else stays the same. ALL my cd labels and ALL the text in the book in front of me does not even shake a bit even though they are smaller font size that the words on the screen.

If I yawn hard, it does that on my sales system monitor - Nokia 17&quot;. Doesn't do it on my office system - Viewsonic 19&quot;.

Does your monitor have a Trinitron screen? The Nokia does, the Viewsonic doesn't.

When I eat something really crunchy, it does the same thing for me. Not only monitors, but also those glowing LCD digital clocks shake up and down.

When there's a full moon out and the declination of Saturn's orbit is exactly 41.3 degrees, I notice that my monitor uses 51.24 watts instead of 51.2352......strange, huh?

You are seeing this because the light from the monitor isn't a continuous wave source. You are witnessing the stroboscopic effect. It's the same reason why car wheels on the highway can appear to stand still or rotate in reverse at night time. The streetlighting (HID) isn't CW either.

Wave a pencil in front of your CRT. How many pencils do you see? :)

Cheers!
