I had a look a few weeks back at a few DLP projectors. The biggest difference I noticed between DLP and CRT was the amount of artifacts on the screen. It was just horrible to look at any angled straight lines. The Iscan Pro took away some of the problem but the scene at the start of Se7en where Morgan Freeman has a metronome on his desk looked awful. I couldn't even tell what it was.


I also saw somewhere that digital keystone correction can cause jagginess. I'm just wondering whether the guys would have had this turned on. I'm sorry to have to ask this here, but most of the specialists in Sydney, Australia are a waste of space and can't deal with anything technical (eg. didn't know how to turn "Cinema Black" on for the Sony VW-10HT even though they'd had the unit for 9 months).


Thanks.

Sounds like you saw a really bad set up with inadequate processing. The DWIN DLP I saw at CES was very film-like with no noticeable jaggies at all.


That's what makes this whole business such a b****! It's hard to see a decent setup unless a fellow member of this group has one and is willing (as they almost always are) to show it to you.

I agree with Dan, you were watching a bad setup. I saw the Seleco 200ht some months ago and the jaggies were horrendous, I attributed this to the poor internal scaler of the unit since they wern't using any PS DVD player or outboard scaler. The LP350 with just the S-video input is extremely sharp and filmlike and you'd be hard pressed to see any jaggies or any other scaling artifacts for that matter.

Thanks guys. It's really appreciated to hear some unbiased opinions.


Dan, Unfortunately (for HT purposes anyway) http://www.avsforum.com/ubb/smile.gif I live in Australia, so it makes it difficult to see other members' setups.


GMan, is the LP150 made by InFocus or where you referring to the DWIN DLP?


Due to WAF, it is almost essential for us to get a 16:9 screen. Since most DLPs are 16:9 inside a 4:3 box, is there a way to setup DLPs for a 16:9 screen?


Thanks again.

Jamie T,


You could wait for 16x9 DLP's, or what you would need is a scaler or a projector that projects 4x3 in a 16x9 window. However, you would probably need adaquite masking above and below to take care of the light spill that would exist.

The LP350 is made by Infocus, I'd like to mention that I have also seen the Marantz DLP (800x600) and it also did not show jaggies with a PS DVD player that it was connected to.


Even the Seleco 200HT from what I've read gives a smooth film like image if fed with a good scaler or HTPC.


In any case most digital projectors are capable of producing extremely good images if the images are processed by good quality scalers. I mentioned the Seleco because it is a great projector but if not fed with a properly scaled image it too will exhibit jaggies.


What were the projectors that you looked at.

Gman,

Um, just wanted to mention that the Marantz VP-8000 (800x600) is unable to be connected to a PS DVD player, however the VP-8100 will accept the 480p input. The component input on the 8000 accepts only 1080i or 480i input so you must have seen an interlaced signal when you saw the projector. I used to sell these projectors and do not any longer bc there are far better deals in the professional market for less than half the price.

Thank again fellas for the replies.


GMan, I've looked at the Proxima, ASK M5, Dreamvision and Davis DLP projectors. They all had jaggy problems but were being fed by a non-progressive scan DVD player. It was cleaned up a lot when the DVDO IScan Pro was used, but since I'll still be watching a lot of interlaced video (Digital TV has been completely stuffed up here by our politicians - we have access to 1 SD set-top box so far), is DLP still the way to go?

Hi Steeve


This was what I was told when I saw the Marantz, but I must admit that the sales person wasn't exactly that knowledgeable, I'm almost possitive it was the 800x600 DLP (I have the broshure so I'll check later). The image was good however and I didn't notice any jaggies. I know the unit was overpriced since I bought the LP350 at half the cost for a better picture. I just mentioned it as an example of DLP units that didn't have jaggies.


Jamie


Some of the units you mention are, according to other members, supposedly very good units and should have given you a very good presentation with smooth filmlike appearance (no jaggies). As far as interlaced video is concerned all I use is S-video (interlaced) with the LP350 from DVD and Sat. With Sat however I put the unit into it's native mode. The quality of Sat isn't that great so if scaled up it would look bad on many units. Non anamorphic DVD's depending on the quality of the transfer sometimes displayes a slight amount of jaggies (but hardly noticeable) Titanic (excellent transfer) vs. 2010 (poor transfer).


Other factors for DLP that you have to ensure will not bother you when comparing to CRT projectors are of coarse black levels and compared to other digital projection technologies you have to make sure that the rainbow artifact isn't going to bother you.


I guess what I'm trying to say is that digital projectors have their quirks, but in general, I don't think that jaggies are one of them.
