moonshinewilly Posted April 7, 2006 Share Posted April 7, 2006 I'm still looking to but a projector for mobile cinema use, up to around £1500 and am in a debate about whether to go for a dlp (better contrast ratio for money) or lcd (3d-reform and "nicer"). Has anyone got any advice or thoughts on the matter? CheersM Link to comment Share on other sites More sharing options...
mac.calder Posted April 7, 2006 Share Posted April 7, 2006 Will you need to project 'smallish' text - Large heading style text is fine on DLP's, but I find that with things like powerpoint presentations, you are far better off with LCD. If you are projecting video/visualiser type stuff though - DLP, especially if your budget can stretch to a three-chip projector. Link to comment Share on other sites More sharing options...
GregB Posted April 7, 2006 Share Posted April 7, 2006 My understanding of the pro/con is: DLP is better for 'film' because the colour mixing is superior to LCD particularly when generating black. This is due to microscopic mirrors reflecting light (or no light) being used to creat the image. Link to comment Share on other sites More sharing options...
Paul_R Posted April 7, 2006 Share Posted April 7, 2006 One word or warning about dlp projectors and rainbow artifacts..Depending on the specification of the projector some people can find it difficult to watch dlp.

AndrewR Posted April 9, 2006 Share Posted April 9, 2006 DLP 3-chip is better than LCD. DLP 1-chip can be worse. If you have the cash then 3-Chip DLP the one to go for, below that kind of price range LCD's are actually a better choice. Link to comment Share on other sites More sharing options...
Pete McCrea Posted April 9, 2006 Share Posted April 9, 2006 The rainbow effect does casue me issues- but I quickly get over it. The newer single chip DLP's are getting much better- introducing additional sectors on the colour wheels, as well as additional colours to improve the colour rendition. I'd say try and go the DLP way for cinema, but the £1500 budget might be the limiting factor. Look into the Projection Design products, but they do carry a price premium. otherwise consider the newer products from NEC, as they might be worth a look. I'd suggest Christie- but they're DLP products start around £3k ex VAT. Link to comment Share on other sites More sharing options...
ampcats Posted April 10, 2006 Share Posted April 10, 2006 Just echoing AndrewR's comments - I picked up a 21 segment wheel, 1 chip viewsonic last year for home use - certainly not good for PPT shows as mac.calder states, although great for movies - the rainbow effect on first use, it was easy to spot, but the brain gets used to it quickly and hides it well, although it can be seen if you move your head sharply, as Little DJ attests to. People are not expecting screen one at Leicester Square when they go to a mobile flick house - and as far as lugging gear around, I always prefer stuff with fewer mechanical parts that can get disturbed in transit (I'm taking lids of mac 250's on a regular basis for transit caused issues - don't fancy doing it to projectors too) - LCD gets this vote - partly for the rainbow effect, and partly for mechanical concerns A.

Hambone Posted April 10, 2006 Share Posted April 10, 2006 I use a pair of 3500 lumen Optoma EP759 DLPs. I only notice the rainbow effect if I look at the screen, then quickly away. IMO, it's not even noticeable in normal use. I do all of my graphics at 1024 x 768 (which is the projector's native XGA resolution) and use the DVI connector, and the resulting image is super crisp, as there is no anti-aliasing needed. Avoiding keystoning makes the image crisper, too. They're not very robust, though, hence the price. As long as you flightcase them and avoid smoky environments (soon to be everywhere public in England, hopefully!), they're great value for money. I picked up two of them, two wide-angle adapters, and two Da-Lite 8' x 6' rear projection screens for £3400. Link to comment Share on other sites More sharing options...
moonshinewilly Posted April 10, 2006 Author Share Posted April 10, 2006 Thanks a lot to everyone who has replied to my query, plenty food for thought and I'll pass on the forum details to the other people involved in the purchase for perusal.

jcgoldcoast Posted July 25, 2006 Share Posted July 25, 2006 Value for money, I would have to go for a DLP Projecter. In the long run, they will last a lot longer than an LCD projecter as the DMD in the DLP projecter will not "fade" over time as an LCD projecter does. They may be a little more expensve for the projecter and the lamp, but you are going to keep it around for a lot longer than an LCD projecter. When I was at school, we had some LCD prjecters installed in the class rooms, and 3 years later when I left, the projecters were virtually unusable because the LCD pannels had faded so much. We had a few DLP projecters installed in other rooms about a year after the LCD ones, and they are still going strong (granted they have only been there for 2.5 years, not 3.5 as the LCD ones have now been installed for). I would be much happer paying slightly more for a product that is going to last a lot longer. Link to comment Share on other sites More sharing options...
SeanT Posted July 25, 2006 Share Posted July 25, 2006 Get a good quality ex-hire LCD, our pair of Optomas (exactly the same as Hambones apart from the lenses) look bloody awful next to Sanyo XF45 (a few years old), XF30 (5+ years old?) and a Sharp V10 - bear in mind that lamps for all these old buggers are as cheap as the optoma lamps and are the only parts that will go wrong and can't be fixed in general - we do use the 759s for situations where both screens need to match though. School classrooms are not a favourable environment and tend to get left on a lot.... Link to comment Share on other sites More sharing options...
