Very true! I've got the original NEC Multisync (JC-1401P3A) and in
interlace it is impossible to see anything smaller than two pixels high
clearly. This is because both the odd and even scan lines are being
displayed on the same place on the screen. The black lines between scan
lines on a 200 line screen are still there, and the image on the odd
lines is overwritten by the image on the even lines.

If you think interlace flicker looks bad, you should see this!

Others have reported that the same model number works fine in interlace,
so either NEC fixed the monitor, or there's some arcane cabling trick I
haven't discovered.

My solution was to throw good money after bad and buy a flickerFixer. :-)

I don't think the flickerFixer is really worth the high price, but on
the other hand if you offered me what I paid for it, I'd keep the thing.
If you haven't seen a flickerFixed 704x470 WorkBench screen with a
Tapestry image in color 0, you don't know how nice this machine can
look.
