Samsung DLP: Explanations seeked basic tech questions on DLP implementations
Hi guys, while waiting for my 61A750 to arrive in couple days I got some questions regarding the Samsung DLP a750, a little too late now I know but here they are:

1- Which method do the DLP Sammy and 3D Vision combo provides? pageflip or what other method?
2- How does the S3D effect work for this combo? (I ask this because other methods seem to always need 120Hz display while the manuals - both from Samsung DLP and 3D Vision's - specifically intruct to use 60 Hz in all compatible resolution?)
3- Is the Sammy's overscan issue been solved? If not is it affecting gameplay? Is there a work around?
4- How does the "color wheel" technique implemented in Led backlit DLP and for that matter how is the LED implemented to replace the lamp? ( lots of leds in cluster or one big one?)

[b][color="#0000FF"]UPDATE: [/color][/b]
4- Read up on the net and found out that Leds are organized in arrays of Blue, Green, Red to create colors replacing the color wheel. Very nice.

I guess the most important question being is it pageflipped? Folks with this DLP TV: could someone confirms or denies this?

Nobody knows if this combo used pageflipping method or not? Come on guys.

Hi distant,
3D format - For lack of a better name, it is a “120hz time-sequential pixel-interleaved” format.
It is similar to row-interleaved, but the pixels are alternating left & right eye views.
There is a full description of how it works, do a search for “3D Ready DLP HDTVs”
go down to the “Technical links and documents” choose the “3D DLP HDTV Whitepaper”

60 Hz - that’s a good question, I wondered about that too.
On my computer - the samsung tv only shows as being 60hz compatible,
but the 3D works & has no flicker, so it must be working at 120hz.
Shutter glasses operating at 60hz, flicker.
I think maybe Samsung is talking about a 60hz frame rate with a refresh rate of 120hz.

Anyway I hope this helps!

Let me know if you need more info.

Very helpful info. Thanks.
I can't get over the fact that Samsung abandoned DLP product line. Such a superior product for S3D gaming as well as being a HDTV. Now my wife wants to have another Samsung DLP to replace the living room's because it's a green TV and the picture is much better than the LCD. I hope Mitsubishi continues its DLP line with Led implementation to take up the slack. The beauty of this DLP TV is absolute no ghosting except in extreme bright spots and only with difficulty that I can see. LED is just too fast and apparently does not leave any residue lighting to leak thru the other eye.

Don't hold your breath on that one. They've hitched their wagon to laser and think it deserves a huge price premium compared to LED. Hopefully 2nd gen laser if there is one will be closer to 2-3 grand instead of 7.

I was hoping Mits would take on LED tech to fill in the lower end price gap or at least someone should.
