Wow, that looks really good. Ghosting is practically not noticeable at all (especially in the Mafia shot). Much better than I would expect given the horror stories floating around regarding Samsung 3D TVs. I'm still on the fence on whether I would want one, but now they are at least on my radar.

Many thanks for the ghosting test Nobsi, I didn't expect such a low ghosting on this model. It seems this plasma is in the same league or even better than the VT25 from Panasonic.

Maybe the X103 glasses are better than the Panny ones since the technology should be quite similar for the displays.

Did you really get the same results ghosting-wise with the Samsung glasses ? Which model btw ?

My Samsung is the European plasma model PS50C7790. I did get it for 1380,- €.

I initially had the intension to by a Panasonic plasma, but after some research I found that Panasonic does not support any none-mandatory 3D format.
The Samsung does support them all (including checkerboard, interlaced and page flipping) and is cheaper, so I gave it a go and I'm quite happy with this HDTV.
It also looks very good and is only about 3 cm deep.
I can not compare to a Panasonic Plasma, but I don't believe that the Panasonic has much less ghosting.

Regarding the glasses, the original Samsung one (it's the cheaper model without a frame on the lower lenses side) isn't as consistent as the X103 regarding ghosting. It's good in the middle, but nearer to the frames at the outer side more ghosting becomes visible.
The X103 is superior in this regard and also has really large lenses, a very big improvement about my previous eDimensional DLP glasses (based on the old ELSA Revelator design).

I think static picture is not exactly a good test for the type of ghosting plasma produce, that is phosphorus afterglow.

I noticed ghosting on my DLP though, now that I use silverscreen. OFC the usual scenario, total darkness plus bright lamp. Dual projection better be at this level or I'll be angry. )

Shutter stereo is never static, it's alternating 2 frames at 120 Hz.

Hi, Nobsi, congrats for your new acquisition.
It's good to see manufacturers adding support for more formats, and I hope that we'll soon see 3DTVs with DisplayPort input.

Anyway, my concern is with the title of the topic - "1080p@60Hz 3D gaming.." is misleading - "60Hz 3D" would mean 60fps per eye, at least that's how I understand it (and got excited when I saw it ). In your case it should be "1080p@30Hz 3D gaming.." if you were talking about the page flipping mode. If you referred to the 1080p checkerboard mode.. it wouldn't be correct as well, because it only delivers half of the resolution (therefore, "1080p" is not entirely true). Just my thoughts here, no offence.
I wish you thousands of hours of good S3D gaming on this baby .

Yes, Zerofool is right. The title is misleading, and I thought the same thing when I first saw it. In regards to HDMI 1.4 the nomenclature designates a few different options such as 720P@60Hz, 1080P@24Hz, etc. In those cases, the Hz is referring to the refresh rate of the source material (ie game or movie) with a single frame containing both left and right eye views, irrespective of the refresh rate of the screen or of the shutter glasses. In both those cases the display and glasses still refresh at 120Hz. Also, there is an optional mode in HDMI 1.4 called 1080P@60Hz, which refers to a frame-packed input of 1080Px2 refreshing at 60Hz. This is then processed by the TV and displayed as if it were a 1080P@120Hz page-flipped signal. Again, the display refresh rate and shutter glasses rate remain 120Hz. So claiming that "1080p@60hz is possible on Samsung" is extremely misleading, even though it is arguably true (but only in the language of legacy 3D systems, not the modern standard). So you may wish to edit the title and call it something else, like "1080p@60Hz page-flipping" to differentiate it from HDMI 1.4.

Sorry for this confusion, I' m obviously just to old fashioned regarding 3D. I edited the thread title to your suggestion.
I just felt the need to publish my findings since anywhere is told that Panasonic HDTVs are superior for 3D, but Samsung HDTVs have also their advantages (and are a lot cheaper).

But still 30Hz per eye is a lot better than 24Hz, though it showed up that at least for me 30Hz is still not playable. I feel a discomfort at that frame rate that I don't get after hours at 60Hz per eye.
(Note that this has noting to do with flicker since the HDTV shows every frame twice to output at 120Hz frame rate.)

So are you saying that the glasses still shutter at 120Hz?

Nobsi, man you make me have to buy updated computer equipment. I see your discovery. And it is quite interesting. I'm thinking your getting 60 different frames per second. I don't have updated computer equipment at the moment. I will be looking at this on my panasonic. It should yield fantastic results- kinda like your saying

cheers everyone

Yes, 60 Hz output would produce aweful flicker in 3D.
The TV does the same for 24Hz blu-ray input, otherwise it would be unwatchable.
I'm not sure though how often the frames are repeated, but my guess is 2 times:

24Hz * 2 (splitting left/right) = 48 frames * 2 (multiflashing) = 96 frames
That would be the minimum to get no flicker with shutter glasses!


Oh, sorry for that

I think the 3d TV's use something like 3:2 pulldown with 24p material to keep the shutter rate at 120Hz:
L1,R1,L1,R1,L1,R2,L2,R2,L2,R2...

Hi again, I forgot to ask one thing regarding this "1920x1080 @ 60Hz in Page-Flipping mode". What inputs does it work with? Does it work with the VGA PC input? Even if not in full 1080p, like let's say 1366x768 or 720p? If it does, it would mean that there's a slight chance for it to work with the legacy nvidia driver . That would be an interesting experiment - Doom 3 in 3D on a Plasma 3DTV .

Zerofool, thats an interesting observation. I was wondering the same thing. synching I think maybe the problem. It would be very interesting to know though.

cheers everyone

Hi Nobsi,
can you show me the schematic for your "simple USB powered circuit" please.
