Glare. Turn off your lights. Don't listen to Ken ;-) (But don't abuse your
monitor either)
A little experiment: leave any dumb ol' pic or window sitting on your montior.
Look at it. Turn off the lights. Look at it again.

trinitrons have 2 lines across the screen. I don't like them.

Noticed here too (mine is 2.5).

Brightness affects gamma because it shifts the black level.
That test image is designed for brightness and contrast only.
The brightness adjustment sets the black level so that all
levels are visible. If a monitor cannot display all the low levels
then there is obviously something wrong with it. This has nothing
to do with monitor gamma. Contrast is adjusted to get full white
and is dependend on ambient light level. Gamma affects things in
between.
> When explained right, gamma is easy to understand and set.
Yes. Find monitor gamma with http://www.povray.org/binaries/gamma.gif.
Put gamma/desired_gamma to the adapters gamma box. Adjust brightness
so that black isn't visible. Adjust contrast to get full white.
Now, if we get all the readers to set their monitors to some fixed
gamma then there wouldn't be threads like this :)

The two lines on a trinitron-screen are technical needed, as anyone can
imagine. But the ability of such a tube to show the pictures without
disturbing *any* pixel-line with small grids makes the two lines acceptable.
Comparing trinitron (or other screens with same technique) to ones with
"old-fashioned" tubes makes the difference clear ...

So OT and yet so relevant to this group.
I like less color saturation on a television screen, to the dismay of many
people over the years. It's really funny when I see someone's TV having primary
red for skintones and greens for grass or leaves I can't see in the real things.
All I have to do is look at the stuff around the TV to know things aren't that
vividly colored. It's as though people want to be looking into a screen with
natural-times-3 color, a sort of neon light reality. Back in the days of
Black&White television I guess the debate was how gray or how black and white it
ought to be.
Many times I tried to adjust peoples sets or at least try to convince them of
their misguidance and I would get turned away from my attempts.
Right this minute I'm in a room with one energy-saving fluorescent type bulb
overhead (made to look incandescent though) and the increase in the redness of
everything makes it look like sunset inside here at night. Doesn't matter
though, I would still compensate and tone the red down on the TV or monitor,
which looks fairly blue. Artificial lighting could be the most common cause of
the discrepancies, and even filtered daylight being very blue when artificial
lighting isn't used might tend to make a phosphorescent screen lack in color I
guess.
Anyway, I couldn't get that test image to work right I think. It had me setting
the brightness down all the way to see it as instructed.
The POV-Ray gamma gif test had shown 2.1 as the best fit.

Since I'm a computer professional, I make a good excuse and get Trinitron
exclusively. It has kept me a size smaller, or to getting a little less in the
computer, but having used them so much and compared them with others, the money
is well worth it.
Another thing that I find very nice about Trinitron tubes is that since they
are sections of cylinders instead of spheres, they are completly flat on any
line from top to bottom. Thus, if you have reflected glare from overhead
lights, tilting the monitor just a tiny bit will usually get rid of it.

That's what I get when I walk into the tv department of a Sears or
Montgomery Ward's, multiplied by twenty television sets.

Same folks who add an equalizer to their audio systems and then move
the sliders for each band to the maximum setting. Forget about a flat
frequency response in their listening area...

Don't get me started on sound, not only do my parents always think
that there's something wrong with the colours on the TV, but there's
always something wrong with the sound aswell. They don't like it
if they can hear anything in the trebbel range, so if you hear a pin
drop in a film, they think that something's wrong with the sound.
Not only that but they have it turned up so loud I can't watch any
programs with them, I have to go into another room and watch a TV
with a volume setting that doesn't make the light fitting rattle.
Maybe we should move to Off-Topic.
