If you want the whole cinema experience, rather than just a big telly (which it sounds like you do), I'd say go for it. Sure, they work best in a dark room, but if you are watching a film what does that matter? I use an 8 foot wide (110" diagonal) screen and coupled with a surround sound system it is fantastic (IMO).

Sure, the bulbs are expensive (and this could be a problem if you buy second hand), but my projector is well over 5 years old and still on its first bulb.

I haven't looked at the market recently (I'll probably upgrade to a new projector when the bulb in the current one eventually expires) so this might be out of date, but here goes:

Traditionally CRT projectors were the best, but expensive and requiring professional setup. LCDs are / were cheaper, but don't give the best image quality (they suffer from something called the 'chicken wire' effect). DLP falls somewhere between the two.

As a rough guide,

More pixels = better
3 panels = better
Native 16:9 panels = better

For standard definition at least, driving the projector from a pc will give better picture quality than anything but a top spec DVD player .

Personally I wouldn't buy a projector without road testing it first. The main variables are brightness, contrast (how close to true black can it achieve, image quality (chicken wire effect, etc), and NOISE - some projectors (particularly older 'office' projectors) have very noisy fans. There are lots of home cinema review sites on the web which can help - try:

http://www.homecinemachoice.com/

http://www.avforums.com/

However, like with ribs it all comes down to personal preference - take along a film that you know well, with lots of fast action sequences, bright colours, dark scenes

Cheers

Chris

I know what you mean about the LCD projectors - a mate had one and the result was quite strange - like 3 seperate streams of light that wouldn't even light up dust in the air. The thing kept losing focus all the time as well - seems there was no autofocus on a 1,000 projector - my old slide projector had it..............

I am seeing our web designer next week and he has set up quite a nice home cinema - I will ask him what his setup is - he's always been into this sort of thing.

Well it shouldn't be that bad - sounds like a faulty projector. The chicken wire effect is just the pattern you get in the image caused by the borders between individual pixels - I would imagine it is much less of a problem with a modern projector. Similarly the focus - mine doesn't have autofocus, but it is rock solid and never needs adjusting.

Cheers

That's because it doesn't need it. An auto focus slide projector also has to be manually focussed for screen distance. A slide projector then uses auto-focus to cope with slide mounts of different thickness and possibly different materials fitted into a loose slot and also cope with an image on a medium which expands considerably with a rise in temperature.

As usual Codders, without Google you only have half a brain.

In my case, what I would agree with is a poor ability to display fixed images as in a presentation. However, like you Codders, I have a pal whos job entails presentation and his LCD projector was designed for that purpose and it is good for that but it is poor at showing moving images, as in a film, so I guess there are different design considerations for the two types of display.

You need to learn to forget the equipment and get on with enjoying the film.

Why do you respond to every comment I make with an attack??? If I can remain civil so can you..........

I am well aware that autofocus on a slide projector was to allow for the slides "popping" with temp rise.

Obviously in a LCD projector heat also comes into play and some sort of autofocus is needed to keep things sharp - several projectors i have seen didn't have this feature and needed refocussing from time to time.

Yeh, I apologise for that but you talk so much shit it frustrates me.

Whilst I could envisage a situation where really poor design made this necessary, I simply don't believe you. As Chris123 said, my experience is that focus is rock steady.

Yes, I know. It was deliberate.
