Sony Pearl and Wierd Colour Band

Hello Guys,
This may be normal, but I am just wondering if its anything that should have me concerned...

Running the vertical lines test pattern on the DVDO VP50 (alternating columns of one pixel wide black/white lines) I can see a purple blur down the edge of each black line and can find no way to get rid of it.

You cant really see it back from the screen, but can right up close - it seems me that the colours aren't lining up or something?

As I said - this may be normal...?

Re: Sony Pearl and Wierd Colour Band

Actually, I can see this happening everywhere, mainly where there is sudden change of colour from one pixel to the next...

Re: Sony Pearl and Wierd Colour Band

Difficult to say without looking at it, it could be a very slight panel alignment issue, or it could be chromatic abberration of the lens. Given that you can see vertical black lines it suggests that the issue isn't particularly bad (probably within Sony's tolerance for this type of issue).

If it doesn't affect the picture on real world video material at a normal viewing distance I wouldn't worry about it. Obviously, if it is bothering you, you should talk to your dealer.

Re: Sony Pearl and Wierd Colour Band

Its really hard to show, but on this photo you can just see the purple blur down the right of each black line...

Re: Sony Pearl and Wierd Colour Band

Done a bit of reading, seems that one of the panels (or two) are 1/2 pixel out...

I wonder if there is way to fix this by adjusting the picture.

Re: Sony Pearl and Wierd Colour Band

1/2 pixel if that, looking at your pic. It's a bit tricky to say from just a photo and it's up to you, but I'd probably consider that acceptable; I doubt you'd ever be able to see it in non-test pattern material, and probably not at all from a normal viewing distance.

Re: Sony Pearl and Wierd Colour Band

Sony has a tolerance of up to 2 pixels out, which is huge! I only allow up to 1 in certain areas of the screen, what you see there is pretty damn good, i would guess a metre bac you cannot see it and certainly not from viewing distance also will depend on connection type as you may be seeing ringing.

Waza,

That is a good combo, Pearl/VP50.

Is there a marked difference in picture quality with using the VP50 rather than the scaler in the Pearl?

It is a combo which I may go with myself, is there a plus in scaling up the 1080i SKYHD to 1080P. I have HD going straight to a Toshiba 1080i set at the moment and have been waiting for the 70" SXRD rear pro, but might go with a Pearl instead.

Sorry for the slight OT, as Els said, looks like you have a slight 1/2 pixel out.

Nick

Re: Sony Pearl and Wierd Colour Band

Hello Nick,
Definatly for SD content, because there are more pixels, there are more visible gremlins on an SD picture.

Ive not really been able to see much of a difference with 1080i content though I havent really looked - I will test it out later.

Re: Sony Pearl and Wierd Colour Band

I also have some concerns regarding pixel alignment on my VPL-VW50.

I have just paid a lot of money for my dream machine and am not happy to have to "make do" with something that is not quite right just because Sony feel that it falls within their boundaries of what is acceptable.

Please have a look at the image attached and let me know if any of you think this is OK.

I got my machine from www.stoneaudio.co.uk. The guys there were really helpful, am I being unreasonable in requesting a replacement?

Sorry Waza, I'm new to this and just feeling my way around the site. What do you think?

Re: Sony Pearl and Wierd Colour Band

As you can see, the red drifts 1 pixel to the right and the blue 1 pixel to the left.
