Ghosting on 65VT50

Hey! Thanks for posting! I was waiting for a testimony on this set. Can you please run this test? http://www.avsforum.com/avs-vb/showthread.php?t=1291751

That's total BS from Panasonic if you ask me. It's no different (if not worse) than first generation 3D plasmas from Panasonic. I guess I should go with a BenQ W7000 DLP projector this year.

Have you tried 3d in 48hz mode? This is only an option for 24fps content, but it does, indeed, reduce crosstalk somewhat, as I can attest to this from seeing the ST30 last year. However, the flickering in this mode in brighter scenes, at least on the ST30, made it unwatchable for me.

Alas, someone in the UT50 owners thread mentioned they didn't notice flickering in this mode and it made a significant difference in reducing the amount of crosstalk they saw, so maybe the flickering is tolerable for some people in this year's panasonic plasmas... who knows?

Obviously, Panasonic's focus is on 2d picture quality, and understandably so, since that will generate far more sales and interest than an improved 3d picture would at this point in time. Really sucks for those of us who detest even the slightest bit of crosstalk and prefer plasma to, say, this year's passive LG's or a DLP setup.

Anyway, though, it really is surprising they couldn't at least improve crosstalk to compare to Samsung's plasmas!

jbug, can you run the test again on 48 Hz?

That means that in reality crosstalk didn't get any better. Did you make sure you had that 48 hz mode working?

So is the 48hz mode acceptable on the 65" VT50? Flicker not an issue? and other benefits to 48hz mode like better motion in 3D. Also, can you activate the motion smoother in 3D?

I was at a shop today and run the test above on a 50ST50. I was given a pair of Samsung bluetooth active shutter glasses. The results are strange. While viewing through the left eye the numbers for the right eye were all pretty dark unlike on my GT25. Hovewer they were still visible, the threshold of visibility was around 20. BUT, while viewing through the right eye the image was like you was still looking through the left eye, i.e. the picture for the left eye was more visible than the picture for the right eye (which was still visible up to number 1 but was in different color). I think it's a compatibility bug with samsung glasses. So, jbug, I believe VT50 must do better job than your set does.

Here's some test picture for eye-measuring crosstalk (from Mass Effect 3) http://clck.ru/d/GoZQ0Ex415Ahv

That's good news, so you didint notice any flicker? When I put my vt30 into 48hz I got a lot of flicker when it was a bright scene.

I'm the guy that posted in the UT50 thread about this,the 48hz in 3d doesn't flicker as bad as in 2d or for some at all and it pretty much gets rid of all minor crosstalk and makes the 3d very acceptable. You can also try setting your players 24p on or off in conjunction with the tv's 48hz to see what works best for you. I have found there is a difference in the refresh rate between 2d and 3d pointing a digital camera and viewing it that way.

I believe the VT50 will display 3D at 96hz - it's one of the selling points over the ST50 and GT50 series that display 3D at 48hz.

Theoretically 96hz should reduce both flicker and crosstalk over 48hz. 48hz (or any 24hz sampling) will typically reduce crosstalk compared to 60hz. 60hz, whether created in the deck or the tv, has to have some sort of pull-down or frame/field interpolation going on to display 24p source material - and all the methods of displaying 24p source material at 60hz are likely to increase crosstalk.

Also, for the best quality 96hz or 48hz playback remember to make sure your blu-ray deck output is set to 24p (or 24hz on some systems). Otherwise, the deck is adding pull-down (60hz fields) to the imagery and the TV has to process ("reverse telecine") the decks output to get the footage back to 24p (24hz) before it can display as 48hz or 96hz. The extra detecting/processing from the TV is not always flawless and can be prone to hiccups, and in 3D every hiccup means more crosstalk.

Until the 3D R/L eye refresh rate (different than the TV's "Hz" refresh rate) is above 140 crosstalk, particularly in higher-contrast scenes, will be a potential issue. (Most active 3D theatrical systems are running a 144 R/L eye refresh rate which is why you see less ghosting there.)

50VT50, watched Toy Story 3 in 3D last night using CNET's settings (except color temp normal) , in 48hz mode, and the PQ was the best I have ever seen in a television, 3D and 2D. Stunning. No cross talk, perfect color, inky blacks. Thank you panasonic

oops meant 55VT50

So this issue is from 65" model only?!

Something isn't right for sure!

Is this ghosting on just 3D or on regular TV?

Reason I ask is currently have a 70" Sharp Quattron LED that has horrible ghosting/halo effect on sports and I thought this TV would have none of that.

I am returning the Sharp this week and either ordering this tv or the Samsung 65" 8000.

Any feedback wold be great.

Don't mix up ghosting and blooming. Google it.
