I am considering getting a tv projector. I thought it could project onto a
white painted wall rather than a screen.

Will this be satisfactory? Your thoughts please.

That would be ok if the wall was pristine.

Have you looked at the price of the projector lamps and the life of
them?

I've a 2,000 ansi lumens xga projector - it works on a white wall in a room
with pale cream blinds (i.e. nowhere near blackout curtains) and it's
excellent in all but direct sunlight, which does shine through the blinds
and weakens the image. Still, why would you want to watch TV when there's
bright sunlight outside?

Bulbs last 2,000 hours and cost £65 - at our rate of viewing that's
considerably less than £15 per year.

Having said that, I'd probably go for a 3000 ansi lumens next time - mind
you, at the current rate of use, there'll be an entirely different
technology by the time a replacement is called for.

My next-door neighbour does just that, and it's fine. Just matt white
emulsion.

I guess a painted wall gives you a "diffusion screen". I once kitted out
some conference rooms with screens - they were a hit with the (more
discerning) users. The black border in particular makes the image seem more
contrasty. I recall choosing from glass beaded and white lenticular and
going with the latter.

Its not bad - and probably as good as an ordinary white screen. You will
lose some available black levels. The top end screens are actually
dark(ish) grey to look at to the eye, and give fantastic saturation and
black levels on a bright projector - but these are silly money usually!

You'll get a wider viewing angle than with a reflective screen - but need
more power for the same brightness square on.

Buy from John Lewis and you get a 5 year warranty. I have a DLP rear
projector - and find it's plenty bright enough on the economy setting so
expect more than the stated life.

it depends on your circumstances

Q1 - how noisy is the projector
Q2 - how much do replacement bulbs cost
Q3 - do you really want it to so totally dominate your living room

I went through as phase of this

then I realised it was just easier to switch t'telly on

I work in a school where we have 22 projectors. The rated life of a
lamp is around 1500 hours but I have only had one last just over 1000
hours and most run for about 600 hours. They are ceiling mounted and
not abused. The replacement cost is around £220 + vat,I make that over
40p per hour on average. The lamp sare designed to be run for at lest
an hour at a time and do no like to be swithced off frequently. This
experience has been gathered from some NEC VT45 projectors (now about 5
years old) and a number of different models of Sanyo projectors all used
with Interactive Whiteboards. From my experience I would not consider a
projector for general TV viewing

I used to project onto a creamy coloured, uneven (patterned) surface

the brain filters it out and you don't notice

Ceiling mount at one end of the room and you'll never notice it - unlike the
TV which in my experience, does dominate a living room.

It'll suffice,I have an old Sony projector that I bought off ebay for £50
less bulb(Kaput!) I touched lucky on a brand new bulb again on ebay for £70.
Its now working great and have watched DVD films whilst viewing the picture
on the matt magnolia wall,I mainly got it for transfering pics to canvas ie
I select the pic and then project it onto the canvas and draw the intended
picture then paint it.

All the talk so far has been of TV but the projector really comes into its
own for a game of Wii tennis 8' wide on the living room wall.

Despite some other's objections, front-projection is quite a nice way to
watch films / sports at home. I agree with some comments that you don't
want to be using it to watch "conventional" tv, but after watching a
film or two, with a bottle of wine inside us, me and the wife tend to
switch back to Sky-TV without bothering to turn the TV back on.

So... 40" LCD Hi-Def TV + Sky-HD for conventional viewing,
Sky-HD/XBox-360 and Sanyo Z2 for films. Very nice, very handy, and not
at all obtrusive (the TV is by far the most obtrusive item).

Check www.avforums.co.uk about now - that has a forum on screens,
including painted walls / MDF etc. There are (from a poor memory) a few
threads that document that you shouldn't use a brilliant white, rather,
a matt, off-white (grey?) paint to allow greater contrast in the image.
"Dulux Artic White", also rings a bell, but I'll leave you to research
that one.

Personally, I use a 2m pull-down screen. It fits neatly on the ceiling
in front of the curtain rail looking almost pelmet-like in appearance.

Don't forget the usual home-cinema requirements - speakers, etc, that
you're gonna need - there's no point in big-screen entertainment with
poxy sound. You want it big, and all around This was one thing that
caught me out, having spent ~£900 on the projector, having to spend
another ~£500 on the audio (well, I wanted component video switching
through the AV-amp, which limited my choice a little to less-than-cheap
units, at the time).

Lamp-life?, as others have said, yeah, usually 2000 hrs to 3000hrs
(eco), I've had the PJ for ~4 years now, on first bulb, although
thinking now that maybe when the bulb does go, time to replace the PJ.
It's important to understand the the bulb is susceptible to damage when
hot, and particularly when cooling, and know to ensure that the power is
not disconnected whilst cooling (the internal fan tends to run a few
minutes to prevent overheating). A good many people, myself included,
use UPS devices to power the PJs, to provide enough time for the fans to
cool down the device in the event of a power-cut. £50 for a UPS is a lot
less than £250 for a replacement bulb.

One thing to consider is the PJ noise level, at 24dBA the Sanyo is a
nice, quiet PJ, some are less so - it's worth working out where the PJ
is to be placed relative to your listening position, and consider the
noise level from that.

If you fancy "big-screen entertainment", and can justify a PJ as well as
a conventional TV, go for it, it transforms movies.

Good point about the fan running after shutdown. On some it even speeds up
in order to quicken the final shut-down. People who are not aware of the
issues could be tempted to unplug it to stop the noise.

Thanks guys. Lots to ponder.

Nope.

Stick with kick-arse speakers and a cordless phone. From now on,
