OT - Plasma TV question

I'm not an expert, but I have done a bit of research on this for my own
entertainment system.

I have a Sanyo LCD projector that's served me well and I have a pair of
Toshiba Hi-Def displays that I'd buy again, but I don't know any
particular
brands to stay away from.

I would go with a projector, also, but would use a DLP (digital light
processor) driven projector.

You want at least 2000 contrast, and 2500 lumens, I would think.

Yes, and many projectors don't do well with normal ambient light levels
during the daytime. And the projectors that do handle this well, tend
to eat those $200 light bulbs are a high rate. Unless this will be in
an area that Jay can keep a little dark, I'd shy away from a projector.
They simply generate the light levels required for daytime use in a
room with unshaded windows.

Well, this is inside a windowless meeting room -- so keeping light out
is a simple matter.

Do the projection TVs need a special screen, or can you just project
the picture on a painted white wall?

Sounds ideal.

They don't need a special screen, but everyone I know will strongly
suggest one. The screen really makes the display work well and they
aren't cheap either and come in a variety of colors, gain values, etc.

There are three options with a projector:

1. Use a plain white wall. This is a very poor option.

2. Use a special paint made for projectors. This is a mediocre option.

3. Use a special screen made for projectors. This is by far the best
option, but also by far the most costly. A decent screen will start at
close to a grand.

However, many reviews I've seen say if you are going to scrimp, scrimp
on the projector and not the screen. A good screen will last 20 years.
The projector will be obsolete in 3. And each dollar spent on the
screen will return much more viewing quality than an additional dollar
spent on the projector.

I picked up an InFocus 4805 at Costco (a bit more than 1 AMU)
and it came with a 6 ft. screen "window shade" type. Mounted it on
the ceiling, works fine.

My friends went with the screen material (there are a number
of suppliers, check google) and created frame to mount the material,
then mounted that on a wall. This definitely eliminated any
ripple or waves. On the other hand, I haven't noticed any on
my window shade version, either.

Again, I suppose it depends on your definition of "decent", but there are
plenty of usable screens out there for a few hundred bucks. No need to
spend a grand just to get a quality picture.

View them side by side and then you'll see my definition of decent.
There is simply no comparison. If you want to see fine detail in
scenery, instruments, etc., you won't be happy on a white painted wall.

Yes, you will. But a light shade of gray is best.

In the old days of sub 1000 ANSI lumen projectors, screens with various
coatings that increased gain while sacrificing viewing angle were popular.
Also, special highly reflective paints were used to increase gain but
contrast suffered. It's simply no longer an issue. A painted surface is
just fine.

I'm not talking about a white painted wall. I'm talking about a nice,
budget-priced screen. In any case, if the best you can come up with for a
definition of "decent" is "the difference between a $1000 screen and a $300
screen", then you haven't proven anything. You've simply chosen to define
"decent" in a way that tautologically "proves" your point.

Not sure about the DLP projectors, but the normal DLP units are rather
directional in their viewing angle... They look better than LCD or plasma,
but only if you are *directly* in front of them...
