CRT alignment program CRTAT or CRTAT2 or CRTAlign available at:

http://www.winsite.com/bin/Info?500000030936

This is an old, old Windows 3.1 program from the early 1990's, but it
runs even today under XP. It can be freely distributed as freeware.

The program was originally written by Steve Jenkins, here are his notes
from about 1992:

"Version 2.0 contains several new setup screens and options. This
utility allows you to setup and test your Windows monitor(display) to
see if you are getting optimum performance. A must for anyone setting up
Windows systems, also for anyone needing to adjust CRT displays. All
documentation contained in extensive on-line help. Unzip both files in
to the same directory; then run it. REQUIRES - Windows 3.1x and
VBRUN300.DLL."

Now here are my notes on how to use the program with modern LCD displays:

Start the program.

Select the leftmost of the 3 patterns under the "Test" group.

Click both check-boxes to display vertical bars, alternating black and
white, of single pixel width

You should have a perfectly uniform pattern of bars on the screen. If
you see moire distortion, it will be very obvious, then you need to
adjust your dot clock frequency and phase to eliminate it completely and
get a "perfect" pattern. If you can't get there, try changing the
refresh rates of the video card.
