I have one of these, should have the service menu codes somewhere. IME the
geometry alters when there are white titles scrolling up on a black
background etc. Not particularly impressed. OTOH, I've got a Philips I got
cheap, "BlacklineS" apparently, curved screen (not as curved as some,
similar to an FST monitor), and the geometry is far better on that. I think
flatscreens seem to have more geometry problems.

When picture size changes depending on the amount of white on the
screen, the cause is poor EHT voltage regulation - the extra beam
current causes the voltage to sag, and the scan signal can then drag
the slower beam further. There really is no excuse for this in a
modern TV, particularly an expensive one.
