We have a new Samsung DLP (HL-S5088W).

We usually watch it with lights on in the room, and I'm happy with its
picture.

The other night, we tried watching a movie with the lights off (or
almost completely off).

My first reaction was that the TV was now too bright, hurting my eyes
in the dark room. So we set about defining the TV's "Movie" mode
setting for the few times we decided to turn off all the lights and
watch a movie.

We found a setting that seemed like it had nice contrast, but that had
the brightness much lower than usual to compensate for the dark room.
But the next thing I knew, I was looking at a scene of Val Kilmer and
Robert Downey walking outdoors at night and thinking "There's no WAY
that their jackets and the shrubs behind them are supposed to be
completely black without a bit of detail!"

If I turned the brightness up too much, any white or bright scenes
were going to sting my eyes. And just mercilessly reducing the
contrast didn't seem like a great idea either.

Other than simply turning down the contrast, is there any other way to
get more detail in the dark areas without making the bright areas too
bright?

Thanks in advance for any suggestions.

turn down the brightness and leave contrast alone. if your set has
good engine, this should effect overall color. the samsung hl-s..
8[7-8]w is an outstanding digital tv, my favorite beside the jvc d-
ila, but some say it's too bright and hurt the eyes. there should be
some light behind the tv, but not in front of the tv. Might be next
time you change the bulb, use a 15% less wattage one?


Four years ago, I bought a DLP set and had the same problem - - too bright
for evening viewing, so I, too, turned down the CONTRAST. We all know that
turning down the BRIGHTNESS will throw all dim detail into a single black
level, so that's not the answer. Turning down the CONTRAST throws away
information, since there's only one way to reduce over-bright highlights,
and that is to chop off the most significant bit or bits of information that
the DLP chip works with. That leaves only less significant bits to render
detail, but there's not enough of them to cover the whole gamut of levels in
the picture and the result is blotchy tones in a paint-by-numbers rendering
of dim areas - - if those dim areas are skin tones, the result is equally
unacceptable. After two days of ownership, I took it back and bought an LCD
rear-projection set - - a world of difference.

Since then, I kind of thought they improved the rendering on DLP sets by
running a chip with more bits - - instead of an 8-bit chip, use a 10-bit or
12-bit chip that leaves enough information levels after controlling
highlight brightness with the most significant bits. Of course, they can
always "have in the wings" an 8-bit chip TV for someone haggling for lowest
price. I think it's odd that peak brightness can't be controlled in some
other manner - - perhaps a 4-bit monochrome LCD just there to control the
level of white light. That would make an 8-bit DLP quite a bit more
acceptable in my opinion.

My advice - - go shopping some more and see if you can find something that
works better, even though it might cost a little more.
