Make sure that there aren't any power cords near the video cable or wrapped
around the monitor. The 60Hz can couple into the signal changing what you
see. Also try changing your refresh rate setting. If it is 60 Hz coupling
in, you should see the distortion change when the refresh rate is changed.
It is very odd that the vertical size changes. If it is a CRT do you have a
deguass button?
If you have an LCD with a digital connection option it should be much better
than the analog connection. (Sorry Bill, analog isn't always better) Also a
digitally created image (freecell) should show perfect geometry on a LCD
screen with a digital connection. There is nothing to stretch.

I have a 17" Samsung SynMaster 753DF monitor and an NVIDIA GeForce2 Pro
display adapter. The monitor produces a stable image with good color
and contrast but has always exhibited a problem wherein the horizontal
size of the image varies with horizontal placement on the screen. It's
normally not a problem and generally not noticeable unless looking at
detailed, rectangular things like architectural images.

From my limited
knowledge of such things I assume the hozizontal oscillator is changing
frequency as it moves across the screen.
Surprisingly, I just now noticed (by measurement and not by eye) that
there is a similar problem in the vertical axis but this problem is not
symmetrical about the center. Cards at the very top of the screen are
16mm tall and only 14mm tall at the bottom of the screen.
I just went to examine the monitor on my wife's computer (even cheaper
stuff than my cheap stuff) and see that the horizontal size problem is
there as well and even more exaggerated. The vertical size, however, is
consistent from top to bottom.
