I was getting ready to lay down my gun and surrender to digital until I saw this post on the "A" site. This is a 2 pixel cross hatch pattern from an RS1. My comment is simply Yuck!

Could you imagine how it will look 2-4 years from now with the projector temperature cycling over time? Keep in mind all you have is static "Panel Registration" adjustments meaning all you can do is shift whole panel obviously the error is non-linear.



After seeing this there is no way in hell one of those are going into my theater anytime soon.

Mike

Wow, I'd be thrilled to have paid five grand for that. It would look even better - I'm sure - after you put your anamorphic lens in front of it. Rolling Eyes

I wasn't going out tomarrow to get one. Smile That would look like total sh*t on a black and white film & no way to fix it.

How about a hammer? I bet that would fix it real good.

No no no, you use a soldering iron to fix it, like this one.

Tres bien, mon ami. Tres bien.

In other news, wtf? I never see any problems like that with the low-end PJs we use in our sims. And not in the Mitsu 1080p LCD PJ we tried, either. I've had routinely better experiences with the cheap PJs I use than any of you guys or others with the high end sh*t... maybe people just need to start buying crappier digitals! Razz

A few months ago I purchased an inexpensive digital to use for games and general PC stuff. Its a Panasonic PT-AX200 and for the most part it is fine.

But the panel alignment is TERRIBLE, absolutely unbelievably bad. I sent screen shots and talked to the customer support people at the place I bought it from, they had me talk to the Panasonic people. They told me to send it in for 'adjustment'. A week later I got a call from a tech who wanted to know why I sent it in. I told him what I thought of the alignment. He confirmed that it was off, but "well within spec for these projectors". He went on to explain that the blocks come from the factory with no possibility for adjustment. He had several replacement blocks on hand, but said they were all worse than the one I already had.

The projector was not expensive, and in most other respects its great: very bright, okay colors, quick panel update. But especially for someone who has had CRT projectors for a long time and cant help but spot convergence errors its really pretty sad. Not having any user controls is bad enough, but not even having anything the techs in the repair facility can use to adjust it seems unconscionable.

This is the focus pattern from the Nokia Monitor Test program. Its looking at the middle of the screen with the lens shift in the center/neutral position. The more lens shift you use, the more the panels diverge.

Actually it might help! Assuming the red error is on the outer edges of the screen, the blue shifts more with an anamorphic due to its wavelength. So, the blue would shift to be over the red (which shifts the least).

All the Panny LCDs have always sucked. Panel alignment is only one of their many issues.

Unless you hate them, get a 720p DLP. No convergence errors, just RBE, dithering and false contouring. Smile But seriously, they are much better than the panny LCDs.

Ya know who buys these sets? People who have been watching 15 year old SD RP sets where the convergence board died 5 years ago. To them, this 'linement' is purty durn good.

I've been to enough homes over the years to know that people still watch 15 year old SD RP sets that are way out of convergence...Very Happy

Some digitals now have ways of 'digitally' (of course Smile) altering the image to fix convergence issues. Makes the picture softer from what I hear, but I doubt that's much of an issue given how artificially sharp most are to begin with.

When/if I'm in the market for one (many years from now) I won't be buying one that can't be adjusted. I couldn't live with that. A friend of mine just returned his Epson 1080 two or three times until he got one that was not horrible but "reasonable".

most of the reason they don't get rid of them is because some are still paying on them... Sad
