I had a notebook computer that had a loose connection between the
controller and the LCD. Every once in a while, you'd tilt the screen and
get a very strange garbled display...

I knocked an entire can of beer onto my MacBook a couple of years ago. You
should see the interesting brightness pattern the screen now exhibits... :-\

Mine is like that ATM. It is still under warranty but I don't want to waste
rendering time sending it back for repair.

The part I can't figure out is... how is the monitor electrically
connected to the metal beam on the underside of my desk? (The desk
itself is wood. And the monitor housing is plastic.) So how the hell did
the charge get into the LCD??

Hey, *I* am old enough to remember green-screen ATMs. :-P (Complete with
"insert card" burned into the screen...)

Resolution, brightness, contrast, panel technology, etc?
Also, do you think they are just simply making more widescreen monitors now,
so of course the price will be cheaper?

Charge doesn't only go through conductors, one of the tests we do is to
apply a discharge to the plastic casing of the display and to the front
surface (which is definitely not a conductor), it makes its way fine to the
electronics :-)

Given that the lead time for one is 3-4 days and the other is 3-4
*weeks*... I'm guessing this has far more to do with market forces than
any technological difference in how "easy" it is to make 'em. ;-)

o_O
I guess if you apply a few thousand volts to something, life finds a way...
...wait...

Oh, please .. I'm old enough to remember when credit cards had no
magnetic stripe, and credit transactions required carbon paper. :-P

Makes perfect sense (ceteris peribus). I'm surprised you cannot figure out
why .
