At least for those with Nvidia cards, there's another factor at work
here: with certain versions of the Nvidia binary driver, you get the
off-by-one "blue line" bug. It manifests as thin blue lines on the top
and left of the image. The lines can be hidden using "xvattr" to make
them black, as documented on this list... but it doesn't solve what I
think is the real effect: it pushes the image down and across by a
pixel.

For displaying interlaced content, that's gotta be bad, since that
would swap the even and odd fields, right...?

Or was that bug fixed some time ago?

P.S. I tried the test patterns on your site, they revealed that my TV
output for the last year has been very blurry, I turned the flicker
filter off and the overscan to max, and now everything is clear and
sharp! So thank you.
