A few months ago, the issue came up with aging CRT monitors, & new
monitors which were out of focus.  For those of us with experience, we would
open up our monitors & adjust the focus controls on the HV Flyback picture
tube power supply.  When this issue came up, I offered my original focusing
images which consisted of the finest possible checker board B&W pattern.

    Now, unless your monitor has a fussy picture & you are willing to void
the warranty & risk exposure to dangerous electrical voltages, I do not
recommend playing with the focus.

    If you know what you are doing, just view the tiled image on your
monitor, at 1 standard video mode lower than the listed resolution your
monitor was designed for, & calibrate the focus.  If your screen is
currently fuzzy, you will probably get a vast improvement.

    I also recommend using my original checkerboard pattern in conjunction
with this new one.  The older focus files are still on my FTP site.
