RSawdey, what exactly does "wobbulated" mean?

Ss I understand everything you're sayig about the 4667 (Samsung rp dlp).

Thanks in advance.

I thought it was a technical term for variable dipulation.

Neat! Thanks for the link jojojojo... not enough details, though, still not 100% clear on how it works...

Thier description of increased speed, saying it went from 60 Hz to 120 Hz, is an oversimplification... I guess it's just another way of saying each frame is composed of two spatial subframes... but they don't talk about the way those two frames are displaced in space.

You can break each frame down into R,G,B subframes, each of which is a separate image on the DLP... with 6 colors at 9000 RPM, you get 300 subframes per second... with 7 colors and 10000 you get 333. Seems to me, if you've got to dedicate half these to the other spatial subframe you'd have reduced color depth...

Timed interruption of the ocscillation of the wheel or a controlled wobble so to speak. This reminds me of gaussian blur for photo's. Slightly offsetting a pixel to "trick" the eye. Comes with a price though, pixelation or slightly fuzzy.......

I've been using that term for years without suspecting someone would actually use it for real. I learned something. Dang.

So, RSawdey, in another thread it seems you like the whites better in the 67 series, but it's wobbulated, which may affect color quality.

I'm just trying to understand all of the different features.

It may be all moot; I went back and measured my entertainment center, and I have a ledge that comes down from the top. It would end up blocking about a 1/2 inch part of the screen on the 67.

The 77, however, would be fully exposed insude my cabinet. I just want to make sure I'm getting the absolute best option for my money.

Thanks in advance for any response and/or additional education.

The comment on whites wasn't mine...

I think I prefer the look of the HD2+ chips better anyway, and also the smaller bezel of the xx77 series. You'll do fine buying this one that fits better...

RSwadey, thanks for all the help on this topic. My first post was in the flat-panel forum, and you have followed me down here.

Many thanks!

We debate the merits of these sets like they are in the room with us. I travel a lot for work and still can't see every Sammy model. We compare chips, wheels, inputs, RPMs', and contrast ratios which are combined in different packages that at times don't seem to make sense.
Even 6-8 months ago you could compare a 5063 and a 5085 and see the difference in PQ & technology right off the bat. Not so easy to tell differences now. I've seen the 4667 at BB but can't find a 4677 anywhere to watch. I'd love to A/B them.

Has anyone?

These sets have major differences.

If we haven't seen them then how do we really know what we're talking about?

Yeah, the process of 'continuous refinement' means comparisons are moving targets...

http://www.popsci.com/popsci/bown/2004/homeentertainment/article/0,22221,767810,00.htmlfunny thing though -when I squint at the original 200x100 pixel images of the eye the left (unwobulated) image looks sharper - the 100x50 jpged versions below show the same effect in my view-- what you would normally see from the proper viewing distance - I notice the same effect when viewing a small halftone image - or any low res small image - I can make out more texture and features at the higher contrast when I can't discern the individual pixels --than if they are just unfocused and blurred by interpolation to a higher count. -ps I put these pix up at 10k jpg but the are displaying as 80k bmp
