Hi Mark, I'm glad that in the case of your projector you got yourself a gud 'un! ![[Smile]](smile.gif)
All I'm trying to point out is that there are a lot of potential pit-falls with VP's to watch out for before comitting any level of hard-earned cash; for all the good ones out there, there are plenty of "duffers".
As for 16mm vs. DVD, lets leave that old chesnut; we'll have to agree to differ and the more time spent discussing it leaves less time for actually watching movies ![[Big Grin]](biggrin.gif) .
Steve, smear isn't an issue on LCD projectors, but the inherent lag of liquid crystal technology (and this includes my beloved LCOS) can produce slightly undesirable effects on fast moving objects. Now this is being HYPER critical and isn't REALLY a problem, but it does exist and all I'm saying is that DLP performs better in this respect, but, in it's single chip form has other issues...nothings perfect ![[Razz]](tongue.gif) . Maybe best not to worry about it...
For me, 3 chip DLP would be the dream because of all the technologies it really, really works the best...but of course it is just far too expensive and unrealistic to consider.
As for really expensive VP's eroding the notion of cheap media, well I don't know...true the discs are relatively cheap, but then most people I guess are taking advantage of the improved quality on TV screens, not VPs, so once you enter the VP market it's a whole different ball game.
You've got to ask yourself what sort of big screen TV you could get yourself these days for £500-£1000. I think you could get a darn good one and (oh dear, I'm gonna be all controvertial here again ) one that picture quality wise, would be far better than a VP at the same cost...albeit with a smaller image.

Hi Chris,
The LED sets are getting very good reviews here in the US. The main advantages of LED over LCD are better contrast, much lower power consumption, and 20,000 plus hour lamp life. LED TV sets are also extremely thin, only 1.0 ins thick. LED home projectors are just around the corner. Imagine that, no need to ever have to replace a $400.00 lamp!
Also in the works are home projectors using laser light sources.

The first "domestic" DLP video projector to use LED as a light source, and now available, is the Vivitek H9080FD. Sadly, the cost is £11.000 ![[Eek!]](eek.gif) !
Also, light output is rather poor at 800 lumens. The big advantage is no rainbow from it's single chip DLP because it doesn't use a colour wheel. Although the price rather negates that advantage at the moment. Expected life is 20,000 hours.
LCD TVs that uses the full-array LED system do offer much better black level than previous LCD displays. Some sets use edge-lighting LED however and are still advertised under the banner LED. These do not offer the same improvement as full-array displays.
OLED (organic LED) was seen as the potential future of TV, with better imagery than LCD or Plasma. Sony managed to get the XEL-1 11 inch display produced but at a ridiculous price. It did, however, show the potential of the format...then the credit crunch hit and development of new TV technology took a back seat.
It seems that now both Samsung and LG are interested in developing OLED again, with LG set to introduce a 15 inch monitor and Samsung potentially investing massively in the production of screens 30 inches and upwards.

Something often misunderstood for video projectors is the relation of the distance of the screen from the projector and the width horizontal of the screen. 16mm film proctors using a 2-inch lens have a picture width of 4'-8" at the screen. With a 1-inch lens the screen image is 9'-4". A video projector having a throw ratio of 1.62 will be at 75-inches from the screen with 120-inch width. You might want to consider if this is acceptable for your outdoor movie showings. If you like your equipment further from the screen the projector may need to have more lumens and a variable focal length lens (throw ratio) for best screen image in your situation.
