    But the new D5 panels support 1080p...why would the res on the projector be 1280 x 720?

    Am I missing something?

    D5 panels come in both 1080p & 720p. It is very likely that the upgrade to the Panny will also be 720P.

    I know we all want a 1080P LCD for around £1500 but that is like asking for a 3chip 720P DLP for £1000.

    I've woken up and realised that 1080P just isn't going to happen anywhere near that price point for a few years yet.

    Maybe Panny will release 720P & 1080P models. But one things for certain the 1080P model won't be in the budget range. Who knows?? Either way we'll find out for certain (I hope) in just over 4 weeks...

    It will be interesting to see or read how the double iris works, i wonder if this is similar to the HS50 iris etc.

    I agree with Zag.

    The curent price for a 1080p LCD projector in the states is $15,000, there is no way that they will drop to £1,500 any time soon.

    I'm waiting for the replacement to the AE700 which will probably have the Epson D5 720p panels.

    We should know more after the September CEDIA show, when the manufacturers show off their new models for 2006.

    Is the price premium for 1080p over 720p LCD projectors justified by the additional cost of building them or just because they can get away with charging that at the moment?
    I guess you have the additional cost for the better panels and maybe a better chip for scaling (?) - what else contributes to the cost difference?

    I'd be more interested in 1080 if I already had access to a player and plenty of films at 720p - but considering even 720 seems a way off (proper 720 not WMV-HD etc) isn't all this a bit premature?

    Sounds like your plans are the same as mine. I’m waiting until after the CEDIA show before I upgrade. Based on the models revealed I will be in a much better position to make my decision. I’m planning on upgrading in November so some of the new models should be hitting our shores around then.

    I reckon I will probably end up with the new Panasonic provided VB is no longer an issue with the new D5 panels.

    Inzaman,

    I think a double iris arrangement is normally a fixed iris inside the lens assembly, olus another before the lens. Maybe the externale one can be adjustable which would be nice, though a high gain screen might be needed for sizes over 6ft wide. Will be very interesting to see the performance when calibrated though.

    Gary.

    Hi Gary, thanks for the info. When you say fixed do you mean fixed as in it does not vary with the scene or would it vary like the HS50 appears to.
    For a double iris assembly it must be some high lumens bulb as one iris brings the brightness down, but two :eek:

    On my Z2 i currently have the iris fully closed (as far as it goes) as i prefer the darker more theatrical picture, especially now i have total black out conditions.

    Its depressing, i am itching for some proper HD stuff.

    Yes, the iris inside the lens would be a fixed size and not adjustable, but the one that goes before the lens could be adjustable.

    My H78 has a fixed iris before the lens and is still bright enough, so had they put it inside the lens along with a variable one before it, then there would be a choice of contrast to brightness settings. That might be more beneficial than using the lens filter which only gains around 300:1, and the iris might achieve better CR with a similar drop in light.

    7000:1+ is not impossible with mods on the Optoma H79 so I'd be quite happy with 5000:1 on the H78 and over 6ft lamberts. But that's just me. :)

    Gary.

    It is a dynamic iris with realtime scene detection.

    I have to agree with PJ here, a 1080p projector would be completely pointless, there is absolutely nothing that you could possibly display which would fill that whole resolution. Even extreme top spec graphics card and CPU with a decent game would struggle to fill that!

    CEDIA is an AV trade show thats held every September in Indianapolis, USA.

    It seems to be the first place that the manufacturers publicly announce the new models of projector that will be on sale for the next 12 months.

    Last year, the Panny PT-AE700 and Sony VPL-51 were shown there for the first time.

    Yep, we are in the same boat. I'm was almost tempted to buy an AE700 for £999 but don't want to be disappointed when the new model is announced so I'm waiting.

    MY PJ is ceiling mounted so ideally i'll swap my AE100 for an AE800 and be able to use the same mount and mounting position.

    I was hoping for 1080p but will settle for 720p with improved contrast over the AE700. I can't see 1080p being around my budget but in a month, I'll now for sure.

    Yes but HD-DVD and Blu-ray wont be around for the common UK-based punter for quite a while yet...



    Would DVI not be able to cope with 1080p? I cant believe thats the case as it can cope with 1600x1200 and I thought had plenty of bandwidth spare.... Or was it just the 15m you were referring to?

    I suspect there is a point at which a 15m cable will struggle with a certain level of throughput. I don't know what that is.

    It was just an off-the-cuff remark, but I think the underlying theme holds true. As bandwidths increase people shouldn't just assume that everything will just work. All the various components which carry and process data are going to have a lot more work to do...PJ :)

    in agreement about 1080p there isnt justifiable need for it yet. there will come a time for it but remember we dont even get 720p so in uk were talking years and years.

    what are the date predictions for our first of many threads titled "Panny AE-900 vs Sanyo Z4 vs Hitachi PJ-TX200, help me decide" :devil:

    702p is all you could need for now - the XBOX 360 will do 720p out of the box and 1080i, but who want's to go to interlaced pictures in HiDef? HiDef DVD's at 720p will knock your socks off. (I guess there will still be a lot of the folks on here complaining that their Blu-ray PS3 can't stretch it's legs with a cheapo 720p PJ ;)

    Why is 1080p such a leap? Obviously the panels are harder to make and you reject a lot more than you do at 720, but the associated cost is in the chippery behind the panels doing the decoding, scaling and image enhancement. They all have to run a lot faster to do their stuff on 1080p images than they do on 720p, so they are more expensive - and frankly rare at the moment.

    Just to show some data for ukkev's explanation, 1920x1080 is 1080p which is exactly 3x the number of pixels in 1280x720. 3x is a huge number in relation to number of pixels that need to be processed and working!

    The transmission standard is 1080i so it's more like 540p.

    I know the likes of gefen do distribution boxes, but would it not be possible to use fibre for sending hdmi or maybe that would require extra circuitry in the projector. What about using cat5e/cat6? I understand the gefen boxes need two cat5 cables (1 for signal and other for control/ddc I think).
