Official Sony VPL-VW95ES Owners Thread - Page 52

Did you ask what is the procedures? Which one should be done first?

Hi,
First i made shift alignment for R and B for both V,H.
After that i use zone alignment for R in the right up of the screen where is still a small shift.
Zone alignment is the same with 0.1 pixel for one click.
For that reason i was asking if somebody has used this feature,because i didn't see any side effect.

Say Hi to Bob for me!...

I really don't think it is normal. I do not see anything like that.

Do you have to exchange your unit or can you pick up the new one first and try it - just in case its no better in that regard and worse in others. Probably not necessary, but I'm just wondering.

Great idea!

I was not able to detect ANY downside whatsoever by using the panel shift function, using either test patterns or real world material. And they make it easy to do this because as you know you can toggle panel shift on and off easily (as opposed to having to back out your settings to get back to 0).

I do not know how they pull this off. Mark H has said for years that the approach used by Sony lowers resolution. Maybe it does, I do not know. But if it does it certainly imperceptible, at least in the small amounts I am using.

What can be easily perceived is the difference between my corrected convergence and the OOTB setting. I can put up a single pixel grid and from a normal seating distance flip back and forth between panel shifted and Off. And as I do I can see the grid turn from a somewhat reddish glow to solid white. It is rather striking. So my philosophy is that if I can see an obvious benefit, but cannot see any downside whatsoever, I'm using it! Although I should also add that with real world material I can't see any improvement in focus or otherwise when I flip back and forth with the panel shift on or off either.

I do not know if the same applies to the zone level controls, but I assume it works the same. Afterall electronic shift is electronic shift. I do recall, however, there is some mention of it in the user manual for the VW95 - it says something about using too much of it may reduce the resolution, or something like that. I do not recall if it is specific to the zone control or the overall shift.

This is pretty similar to mine. Except it's perhaps a bit worse than that at the bottom of my screen, while it could be slightly better than that at the top.
I think it's Chromatic Aberration rather than convergence. Purple fringes are classic CA behavior.
My projector is set up level with the top of my projector, maximum distance back from the screen (extreme zoom), which means that the lens shift is near maximum downwards vertically.

This yields no noticeable impact on the image from more than 4 feet away (100 inch screen), even on test patterns. I don't notice anything on real world material.

Still, I wish I didn't see any CA up close.

When I tried to use zone convergence adjustment to tweak the bottom of my screen, it ended up creating significant pink color shift to one on one off pixel checkerboard patterns. So I abandoned the convergence adjustment.

LOL...You could name it, "Tweekers Anonymous"...Bring your own donuts and coffee...

None off the two I have seen.

I really dont think you go wrong with any off these two - I own the 95 and I have seen the X70 ( Europe name ) and I think, that both looks wonderfull and they both haves many strong points and very few weak points off what we know off for now.

And they can both make a beuatyful picture

dj

No, you can do the overall shift first, and then fine tune some zones for example one the left side alone - so it applies the overall shift adjustment first and then your zone can move it specifically in that zone.

I have seen the same thing. As the nature of the color, I guess the blue infringes more than others. So I hope the overlap is really not a CA issue. I also have the PJ ceiling mount and it is at the end of the vertical shift.

Here I attached two pictures which is before and after the pixtel shift. These are the center portion of the 5th screen shot of the basic settings on AVS HD709 disk. The white dots are the single cells inside the black square.

Before th panel shift, the blue/red/green are visible in up/left/right direction. After a small panel shift, only the blue/red are visible as one outlines the other with the white in the center. However overall picture backgroud turns to be pinkish.

If viewing from the sitting distance, I can pull a single cell or line pattern screen. Strange enough, the white on the before adjustment screen looks whilte and the white looks pinkish on the aftr adjustment screen. The unaligned screen looks better than the aligned.

Why is that?

They both move in 0.1 pixel increments and up to 2.0 pixel

There are one, but it only affects high resolutions patterns like one pixel on / one pixels off - it gets "funny" color and if you use Zones, it can make weird color splashes
But I have for now not seen any "problems" with real material ( but still dont like that it do it )

Ok, I have ordered the 95, have an Oppo BDP-93 on the way as well as 4 pair of the MonsterVisions and the kit. Now all I need to do is make sure my HTPC can pass all types of 3D content. Presently I have a 5 series ATI card and use Arcsoft TMT 3.0 as well as WMC via a Ceton InfiniTV card. For what I understand, the Ceton is good to go and will handle 3D content with my existing graphic card and Comcast but in order to handle 3D Blu Ray iso's, I need either an NVidia or an AMD 6 Series card with TMT 5.

I know it's not the right thread for HTPC nerdiest but woo-whoo here comes da 3D fun.

I get "funny" round color splashes in one on/off patterns - but never seen it on real world materiel ( probely because there isnt very much one pixel on/off details in real world pictures ?! ) - but its a little trade off - live with a little convergens error ( say red edges ) or perfect convergens ( what I can achieve with shift + zone ) ,but a chance for a small high resolutions patterns "pops" up in some extreme scene ? what to do

But as said, never seen it for now in real materiel

BTW have found my first MV setting who is better then the Sony glasses for ghosting ( delay 1720 duty 60 ) a little darker picture then on the Sony´s , but less ghosting - Im getting closer to enjoy 3D

Hi,
It means that you did use shift+zone adjusments to have perfect convergence?

Planning a fun 3D weekend with Smurfs 3D and Kung Fu Panda 3D!

Is that bulb hours or ownership hours?

That's 3 days turnaround shipping

I only watched a few mins of smurfs, not sure I can take the whole movie. KFP should be pretty good in 3D, checking it out this weekend too.

Try the same thing with Delay of 1150 but duty cycle at 60. Does that perform any differently?

I have my Daughter this weekend and she is wanting to see it so I will have to grin and bear it (Smurfs)...

I am excited about Kung Fu Panda though.

Exactly.

Just curious: can you tell me how the "Sony dealers" issue is easily solved?
I'm in Toronto and the only Sony dealers I know are Sony stores (full MSRP price), the occasional high-end AV store (full MSRP price) and some kinda shady looking off-the-beaten-track places (which if I remember still charge close to full MSRP). And nowhere to demo (whereas a number of AV stores demo the JVCs).

So...?

Thanks.

Can you drive to Detroit and buy one there?...Might be the cheapest way.

There are authorized Sony dealers in GTA that are selling the Sony high end stuffs below MSRP. I bought the VW95 a month ago way below that from the local store. I am in Richmond Hill.

Thanks.

It's a bit academic at this point as I'm headed for the JVC RS55. But for future reference
it's nice to have options.
