Getting your eyes checked certainly is a good idea. Many
eye doctors recommend special eye glasses for computer use.
It is even possible that you have some other medical
condition that is effected by a flickering fluorescent light
tube. You should understand that there is a fluorescent
light behind the LCD display and that is how it works. So
you ARE staring at a fluorescent light.
When you get your eyes checked, see an ophthalmologist, not
just an optometrist at the local discount store.
If you use the BIOS or device manager, you should be able to
turn the backlight off. But if you have the light just
turned all the way down that should work too. Using
reflected light that doesn't flicker or cause glare on the
screen is the way LCDs worked before they added the
backlights. Using just reflected light that isn't powered
by 60 Hz power is just a way to see if you are sensitive to
flickering light. Filtered sunlight just means that the sun
is not directly shining on the display and causing too much
reflection.
You also might want to check the graphics settings so you
are using the Clear Type settings intended for use with
LCDs.
Good Luck

| Hi Jim,
|
| I'm not clear on what you mean by turning the backlight
off. Could
| you please explain?
|
| Today I returned the Samsung 920T back to Costco. A
shame, because it
| was on at a good sale price and the monitor seemed to be
of high
| quality.
|
| Came home with a NEC LCD 1970GX. Expensive! It is set
to the NEC
| recommended settings of 1280 X 1024 and 60 Hz. Turning
down the
| contrast and the brightness from 85% to 15% helps, but I
still want to
| turn my eyes away because of the discomfort. No headache
as yet.
|
| The problem seems to be one of glare off the screen. It
is simply
| hard to look at - sort of like staring into a flourescent
light up
| close.
|
| I'm thinking the problem may be related to the high
contrast ratios.
| The Samsung was 1000:1 and the NEC is 700:1. I may also
need to get
| my eyes checked.
|
| Thanks for the ongoing help everyone; I really appreciate
it.
