I discovered the problem in England. I found ways to tolerate the flicker,
but never understood the locals' insensitivity to it.

Still, one needs a standard blue filter to do a decent job. Regardless of
the color bars used, there must be a source, which was the original
question, I believe. As I suggested, a suitable LaserDisc or DVD is
probably the most practical 'signal generator'.

Finally, in response to a paragraph I snipped (sorry), note that digital
reproduction does not mean NTSC/PAL/SECAM compatibility. True, a computer
does not care so the signal from DVD-ROM to monitor should be unaffected,
but most U.S. receivers are NTSC-only and will not reproduce a PAL or SECAM
signal - even if there is a SECAM DVD format (AFAIK, there is not).
