Little bit OT in that it's not any item that's on my bench, or ever will be
....

Just returned from a trip across the pond, and the return aircraft was a
B-767 - the crappy dash 200 model with overhead screens. The large screen
which was on the bulkhead a few rows in front of me, and which I believe was
an LCD not a plaz, had real horizontal linearity issues at the lefthand
side. Nothing 'sharp' or 'digital' as you might expect with LCD display
technology, but a smoothly worsening error, the further you got to the
lefthand side. By about a quarter of the way across, the lin was normal, and
remained so across the rest of the screen. The best way to describe it is
that it looked exactly as a CRT set would, if someone had mis-set the
H-linearity coil.

Now I've been involved with LCD TV sets and monitors since they were first
out, and I can't ever remember seeing one with this sort of effect. Saddo
that I am, I have been wracking my brains to try to figure out just how this
could even occur.

Anyone else ever seen this effect on an LCD display, or have any thoughts on
how it could occur ?
