Are there any experts out there who can tell me if it would be wise to begin acquiring projectors that are HDCP (High-Bandwidth Digital Content Protection) Compliant?

I'm concerned that as we begin using playback devices that have digital content protection built in (such as the new optical disc recorders that are emerging) that we will need to have projectors that are compliant as well.

A survey of the market seems to indicate that the majority of projectors that are compliant at this point are manufactured for the home theatre arena (low ANSI lumen ratings for use in completely darkened rooms).

For the past couple decades home consumer electronics have been utilized extensively in the classroom - TV's VCR's, DVD players, etc. It puzzles me that projectors are being marketed for the home with this compliancy, but not the classroom.

I'm getting a lot of conflicting answers to this question - the engineers seem to be saying that it would be wise to have this feature, while the salespeople seem to be disagreeing.

Any insight?

By the way - I noticed that Mitsubishi has a model that looks as though it would do the job - the XD460U. It has a DVI-D connector that is HDCP compliant (Not all DVI connectors are compliant).

I'm thinking that this would enable us to run and HDMI cable (with an HDMI to DVI adaptor/s) easily from our source (video playback unit and/or computer) to the projector through our 1 and 1/4" conduit.

However, I've never used a DLP projector, due to concerns raised by color wheel issues. Has anyone used this model or its sibling the XD490U? If so - are your colors accurately reproduced? Any problems with rainbow effect? Any other issues?

Thanks for your help in advance!

I would say the answer is 'yes'... but not really.

You see, classrooms don't care about high quality first and foremost, they care about getting something servicable in for the absolute cheapest price.

Poor color? Doesn't matter.
Rainbows? Doesn't matter!
Limited connectivity? Doesn't matter!!!

Up to a point, what I am saying is true.

Doing commercial work currently and I can promise you that the government has zero interest in HDMI or DVI connectivity. They want VGA (5 BNC or 15-pin connection) and composite. Two, and only two types of connectors are all that is required.

You say "Well, what about consumer devices like Blu-ray coming out that may require it?"

No, there is no format that REQUIRES HDMI currently, or even proposed. There are those that require HDMI for the highest quality output possible. That doesn't mean that you can't use the same composite video connection you have used for 20+ years and get the same passable results you have had for 20+ years.

That's the key - there is no benefit to a school, or most businesses, to take advantage of these higher quality connections. The added cost that goes along with it simply is not worth it or beneficial to most companies. Schools especially.

It should be noted that HDMI and DVI have limited line lengths unless you pay even more for optical fiber connectivity. While, RGBHV can be run hundreds of feet over traditional coax or further over new CAT-5 solutions.

I fully believe that the high-end consumer market is driving the commercial market, not the other way around. HDMI will eventually show up on more and more commercial products and DVI is on a LOT of commercial projectors - but not the cheapest ones, because that adds cost. And you are looking at the cheapest ones because they are the most cost efficient.

Price - Price - Price - Price - Price

It does not go hand in hand with quality.

Here is a list of 16 projectors for business - all with DVI (HDCP) connectivity.

NOTE: For home theater, people should have been getting HDCP compliant devices for the last 3+ years as the potential requirement has been known of for that long - or more.

Any truth to the rumors that VISTA (new MS operating system) will require content compliant displays?
