It seemed to me this wow effect is really the "edge artefact" that overscan was made to hide.
I have a 32" "semi HD" CRT TV which has the "wow" shown but on the right hand side, I was going to get the dealer to come and adjust
the set as I had assumed that was a minor malignment of the tube that they might be able to correct. 2 others similar TV's / setups
I have do not have that bendy "feature".
Interestingly the inner bow moves depending on content movement and it is a little disconcerting however I can seem to come to
ignore it. Test videos can well demonstrate the edge movement bending and straightening. See http://www.w6rz.net/
Does anyone know if a degree of tube malignment can accentuate this and will it be possible to have the dealer adjust and improve
