If i dont see 'Screen Door' or 'Rainbows' now, will I ever?

OK, Im considering DLP's but have recently been attracted to the Sony Wega III.


In all my shopping of DLP's I never really see any rainbows. With the LCD's I never see any screen door effect either... even up close! I see pixelation but none of the scary rainbows or screen door effect.


Is this something Ill notice once i get a unit home and spend many hours watching it?

Maybe.

Your viewing conditions at home will be much different than in a store.

I'd guess you would be less likely to be bothered by SDE at home if you don't notice it in stores. As for rainbows, if you notice them in a store then you will notice them at home as well, if you don't see them in the store then I stand by my previous 'Maybe'.

As far as the RP LCD "screen door effect" goes, you're really not going to see it when sitting at a normal distance. Some folks misinterpret the anti-glare texture of the screen ("silk screen effect"), or other source pixelation artifacts, as "screen door effect", but they're rarely if ever actually seeing the grid between the TV's pixels.


In terms of DLPs, the lighting conditions when viewing the set can make a difference, i.e. you may be more likely to see rainbows when sitting in a darkened room. Also, if your eyes are tired, you may see them when you might ordinarily not. Hence, it is possible that you may first experience them later, after you've been using the set for several weeks.

Screen door effect is noticeable to most people no matter what the lighting conditions are. Rainbow effect seems to be more noticeable in low light conditions (for those that can see rainbows).


If you don't see screen door effect now, you probably won't when you get the TV home. You may or may not see rainbows since they usually more dependent on the material viewed and lighting conditions. I didn't see rainbows under store lighting conditions and I haven't seen any on my DLP at home either.

Thanks for all the quick replies!


I guess the GWIII handles the 'screen door effect' pretty well.

If you don't see it don't worry about it :)

If you buy a set and find that the SDE or rainbow bothers you

after the purchase, you should be able to return the set.


I for one can see SDE, well it's more like sense the SDE. That is,

I see a clear picture improvement from a lower res to higher resolution

screen. If I see them side by side I notice the effect is usually due to

SDE. However, even when not looking at them side by side, I appreciate

the more "realistic" picture of the higher resolution screen.


I think SDE is important if you have very good vision. Otherwise it's not an issue.


I'm more sensitive to light drop off/picture uniformity. My one reason for lusting for Plasma.

I saw a Sony 60XBR950 in a store for the first time the other day. I could not see any SDE even when I got pretty close to the screen. It seems all the manufacturers are getting better all the time at reducing that effect.

Actually, it isn't. Most people assume that what they are seeing is SDE, when it is usually SSE. You would literally need the eyes of a hawk to see SDE from a normal viewing distance.

No its not, its word one the worst LCD's for the dreaded screen door effect.


Even when you're no sitting close you can still see the effect. The images and text is just as defined, you can see what appears to be traces of pixel structures, which creates less than a smooth film like picture. Also, screen door effect or any traces of it kills the ability to create a 3-D type picture which decreases realism.

You will see the effect all the way back were you sit if you know what to look for... You see all kinds of lines going down the tv... Put in star wars NH in begining were 3po is waliking in the desert, lines galore in the image...

Should I see lines in the bright areas? I swear I saw NONE in the store. I looked CLOSE up, my nose nearly on the screen and only saw pixels.


Are you seeing black lines?


Does someone have a pic of what the 'screen door effect' really looks like?

This is sort of a religious battle, unfortunately.


But use some common sense here, people. At 10 feet back, you can barely pick out individual pixels on a 50" or 60" LCD RPTV, let alone the tiny black spaces between the pixels. Try putting a solid color background on your TV, something bright, say all yellow. Now look at the TV from your normal viewing distance... Do you really see an incredibly tiny grid of black lines, or do you just see a field of yellow, possibly with a bit of shimmering?


Whatever artifacting you're seeing when you're watching Star Wars, it's extremely unlikely to be the spaces between the pixels. It's much more likely to be a scaling artifact, a compression artifact, or a general problem with aliasing or lack of resolution, since the DVD only has 480 lines of information.


Stop worrying the guy unnecessarily with this. Sheesh.

Well the Sony is better then the Hitachi IMO and overall picture is better then the Panny. So, by default, the Sony handles it the best from what I've seen.

If you never see screen door at any distance then it won't matter what you buy!

Wish i could show you picture of effect but dont have lcd no more... Its not noticeable most of the time from what i remember.. Still a nasty effect though...(One that i could take a pic from 12feet and youd see it) New models still have same effect...

Ive never seen this on the Sony GWIII that i looked at in the store. The pixelation I mentioned was jaggies along edges of moving objects, nothing severe.

Yes, you seem to have it there.


Jaggies are generally the result of scaling, which the GWIII must do to all the signals it receives.

So my question now is, if it doesnt look like this now (pic above) then it wont eventually 'set in' will it?

You could have taken a picture from 12' back, but whatever it was you were shooting, SDE it most certainly was not.

No.


Like NVBoy said, to see THAT grid, at a normal seating distance (>8 ft.), you would have to have literally superhuman vision.
