The X70 is a "fixed pixel display" just like all other digital projectors. They are called "fixed pixel" for a reason, the only way to move the pixels is to move one of the three imaging chips and doing so moves all the sub pixels on that chip. The E-shift system in the X70 creates a second set of pixels diagonally between the normal 1920x1080 grid, again this set of pixels is fixed and is not adjustable as it is a shifted copy of the normal 1920x1080 grid, move one of the imaging chips and the E-shifted pixels move as well.
The E-shift system should allow convergence correction of half a 1080 pixel (one 2160 pixel) as a line uses two E-shift pixels but not less without blur, the 1/16th 1080 adjustment uses adjoining E-shift pixels to cancel colour fringing, thats blur not convergence as you have not "converged" anything. You cant move a colour less than a singe addressable pixel and thats all there is to to it.

Try turning E-shift off and measure line width at a point where native convergence is good and where its out, then enable E-shift with your convergence adjustments applied and measure line width at the same points. I expect that with E-shift enables lines of a convergence test pattern with have softer edges (slight blur) and in areas where you have applied convergence adjustment the blur will be worse and the line wider than where convergence adjustment was not needed.

Other X70-RS55 owners report that E-shift "convergence" adjustment is no substitute for good native convergence and some have had their projectors replaced because of that.

This man definitely knows his stuff. Great contributor and no nonsense no  bs approach.

Out of interest spoke to the Guys at Screen Technics today and enquired at what a 110" 16:9 motorised DNP screen would cost.


Drumroll...................................................................$15,000. (sound of large Clash of  Drum Cymbals)

Definitely divorce material.

You should be happy to know I haven't had the urge to use any lens with this machine either. I did test it out and the results were worse than lens memory zooming. Grid distortion, pin cushion etc. Once 4K is the norm, lenses will be a thing of the past, it's only natural. They were always a stepping stone until res got fine enough and PJ's bright enough.

was my impressions as well, seeing the x90 demoing scope material without lens at the melbourne show.

wow hardly be appropriate for a $3-$5k PJ I would think !

forget about divorce some worse fate likely I would think spending that much on a screen hehe

Well - got my Avatar 3D pack and the Pana glasses are far more elegant than the Epson ones. I'm pretty pleased with the 3d on this disc and the setup and I find it less fatiguing than at the cinema. Interestingly it makes the 100" screen look small when in 3D mode. I guess that is the benefit of a PJ, you can just scale up the image if you have the screen size.

FYI – these still these packs available, Bing Lee in Chatswood got a second pack in for stock.

[MRCRIST]

Yeah I was astounded when I was given the price. Funny that the guy at Screen Technics told me that the screen is best suited for viewing with overhead lights on eg he gave was at business presentation (stopped people falling asleep) the benefits versus cost  with lights off in a non batcave according to him could not justify such a pj screen. I reflected on what he told me and it was refreshingly honest.

Screen Technics are obviously not interested in the home theatre market, their pricing is ridiculous and aimed at business customers with deep pockets and tax deductions. You could fly to Europe, spend a month or two there on holiday and fly back with a DNP screen for less than they are asking.
The big top of the range cost no object curved scope model with motorized masking goes for about $17k in the US, $15k for a basic little 110" motorized screen is insane and a dead set rip off.

If thats the sort of pricing policy Screen Technics have forum members would be well advised to avoid them like the plague.

Here is the link to a EU End User price list (as at Sept 2011).  http://www.rearpro.c...July%202011.pdf

The 100" Core 16:9 UK RRP is a under A$2.9K and that includes VAT

Screen Technics distributor in Oz if memory serves correct also distribute Red Leaf screens and that would be their lower end consumer screen/s..........

Correct  as far as DNP concerned i'm not 100% sure re Redleaf..

yes they do distribute red leaf, which is chinese made and quite decent for the price they are distributors for whole lot of other things too, all on their website. I've only dealt with them re their locally made screens for which their service and support is excellent.

[yorac]

Had a Redleaf screen for a few months a couple of years ago, no problems at all, reasonable quality and thought they punched above their weight price wise, got mine from Hardly's at the time................

+1 Can vouch for Screen Technics and LP Morgan staff. They are receptive to your questions and give you invaluable information about the products they sell.

Two Australian Company's that give you good old fashioned advice and service.

[Owen]

When they overcharge so dramatically I could not care less about their "service", they have made themselves irrelevant.
I should get onto DNP and let them know that their AU distributor is killing their sales down under. When you can buy three screens in Europe for the price of one here there is a real problem.

Okay, so Im thinking about cleaning my projector. In the manual it says it increases the life of the bulb as well as the projector. I have had my projector for around 2 months now so its definately ready for a clean.

Need tips on cleaning! What do you guys use? How far do you go in? All the details from the people that like to keep their projectors lovely.

[roh008]

Just unpacked projector and watched a movie, great out of the box performance. However, can I have advice on how I should set this up? Currently in non ideal surroundings and only temporary. But are there any minor settings I should test and make sure it works as I won't be using the projector till I move house in a months time.

Thanks

Roh

P.S. Dark Knight was awesome with sound cranked up and a stonking image.. four times bigger than my 32inch tv.. haha and likely to be bigger yet in the new place.

good question additk, I had a quick peep at the manual (this is downloadable now) and they recommend 3 monthly cleans of the filter. and yeah given have had the unit and used it over that period maybe a time for a clean seems an easy enough process. they also give some good tips re cleaning the lens etc. so covered well. thanks for the headsup.

they do suggest too to follow the recommendations to maintain long life of the bulb, so only a good thing to do I would say

hey roh, congrats and a beauty isnt it

yeah its really good out the box isnt it ! just have to make sure projector is setup physically perpendicular and level in all three directions to screen. as far as setting on the pj, really thx colour mode and eco lamp power setting is all you need for an excellent out of box performance, so can just sit back and enjoy and yes do give it a good run next couple of weeks. Id say try clock up 30-50 hours which will help surface initial issues if any which are covered with the 2 week DOA warranty. dont forget to register your pj with epson as well, which automatically extends your 3 year warranty to 3.5 years

Jeez such a hard arduous task... lol

Should I leave Auto Iris on our off? Also, I can't hear it so I'm thinking that it might not be working? It's literally 2 feet away in this tempoary set up.

Set it to normal via menu. Put on a contrasty film eg Dark Knight. You should hear a rumble like sound as Iris opens and closes. Mute  volume of the film to assist with obsevation

Thanks for the heads up guys. Just read cleaning procedure. Very well written instructions ie apply KISS prniciples.  Logging out now to give mine a bit of a clean.

I also going to use purpose soft lens brush which uses a puffs of air plus very soft hairs at the end to clean lenses on cameras.


Stop Press


Just cleaned mine. Took a good 5 minutes.

I also can't hear mine even setting it at high and it being located 3-4 feet away, I going to have to do some more thorough observing.


How would someone who has never previously owned a projector diagnose a malfunctioning Iris?

yeah just completed the clean procedure. easy peasy hehe. they make it quite easy and good easy to follow procedure.

guys I dont use the auto iris myself. if activated in normal and in high speed mode you should hear it going with contrasty material as indicated by crist in post above

[eazymann]

On further inspection my Iris seems to be working, when watching a movie with a fade to black scene and it being enabled the whole screen goes completely black blending into the velvet border. When I set it to "normal" or "Off" and re watch the fade to black scene I can just faintly see where the screen and velvet border end.  So i guess it works and it does give blacks a little kick, however I can tell it's enabled  when viewing I see very subtle colour fluctuations when faces are shown for example. Other members in my family cant notice so I might alternate from normal to off from time to time.  I was expecting the auto iris to be nosier than it turned out to be, if it wasn't for the fact I can tell its enabled (very slight fluctuation in colour) I wouldn't even know it was on or if it was at the highest setting.

Hi Guys, well l've set mine up too...just took the old pj down and put this in its place.

The detail naturally is finer than the older Sony 720p , and overall it's a nice upgrade   l'm currently running it at around 3.8 m from our 100" 1.4 gain screen , so even on eco it's pretty bright ( not as bad as l thought it'd be )
The whites and bright scenes are pretty full on and blacks are good but the screen gain and closeness off the pj make the black bars not so black etc.

i'll move it back in the next few weeks and maybe go up a size or 2 on the screen ( waiting to see if Screen Science will help me out here )
l have'nt tried 3D yet as we have'nt bought a player and l'm tossing up whether to go a player or 3D media player such as a HiMedia 900B

Anyway very happy with with the PJ and looking forward to getting it set up properly ( very good as is )

Oh, l'm running the iris on high , have'nt looked at gamma yet etc ...also l noticed when l switched on FI , my audio went slightly out of sync ( l run 7.1 analogues out ) and l reckon the pic got slightly softer ? ( l was tired at the time though ) , l didnt leave it that way as the sync issue bothered me and l could'nt be bothered fixing it lol

Anyway gotta go and set up the wdtv for the kids ,

cheers ken

[:)]

hi ken good to hear have got it up and going to pretty pleasing result. If planning to change screens is it worth dialing back to a 1.1 gain screen as imagine the 1.4 gain not helping things and cant imagine its needed ? worth checking with a light meter to confirm though.

in 3D players the tosh is region free and can be had very cheaply under $100 !
