All,
This discussion got me thinking (uh oh... Danger, Will
Robinson!)...is there any point to having a screen saver on a machine with
an LCD display? That is, is there any advantage to having the LCD pixels
all black (or black with a distraction running around the screen) as
opposed to steady, showing the last thing you did?

There really is no point to screen savers in general. The phosphors in
modern CRTs are far more burn proof than those of old. You can still burn
them, but you really have to be very abusive to the tube.

Of course there's a point: It makes the machine look really cool when
you're not actually working on it. :)

No, we're talking rock-steady picture, but garbled
If the cursor is at the bottom 1/2 of the (logical) screen, you NEVER see
what you're typing
If its at the top half, you see about 20x what you're typing.
Its definitely not a TV adjustment problem.
Thanks, though!

Hi Andrew:
The display 'seeming' to be "rock steady", doesn't prohibit the
sweep
frequencies being wrong by a 'multiple' of what they should be.
Find the adjustments, mark where they are at for now, and try some
adjustments. If it doesn't help, then back to where they were and your
no worse off.
