That is great and convenient that it works for you.

The MonitorsDB file from hwdata-knoppix-0.95 has 3456 entries for various
Monitors to give that horiz sync and vertical refresh information.

At first, I thought it was an indication that 3456 monitors didn't give
information, but I see it also lists your monitor:

 Compaq; Compaq V70 Color Monitor; cpq170a; 30.0-69.0; 50-125.0; 1

The workstation I am sitting at has a TRL 100f monitor as detected by
XFree86. The FCC ID shows it is from Royal Information Electronic's
Company. I had to manually set the VertRefresh and HorizSync. The
MonitorsDB (which I don't use yet under *BSD) has 7 TRL/RIC entries, but
not mine.

My goal for this is not only for this FreeBSD "advocacy" discussion, but
that I have built custom NetBSD Live CDs for a couple years that I want to
have instant X configuration wherever it is used. (With older XFree86 3.x,
my CD provided four different XF86Config files for 1280x1024, 1024x768,
800x600, and 640x480 VESA standards.)
