The ST60 was a hair better than the VT50 at .0016 which is around where the F8500 has been (.0016 - .0017).

I am not sure that I agree that the F8500 produces a good % of led brightness (but better than all other plasmas), but yes, your other pts are valid.

There seems to be mixed opinions on this. To my understanding, the upcoming firmware update should resolve the issue some were seeing. However, Kevin Miller didn't seem to find any issues with it to my understanding, but others like Jeff Meier preferred it off.

What issues (to lazy to browse 8500 thread). The measure without that setting on is pretty weak.

All of these still don't match the black levels I see on my Elite, so i'd take a hit in that area regardless of what I buy. When I saw the ZT60 at the show, my first thought when they showed full screen black was 'OK, nice, but still not as good as what I'm used to with the Elite'.

I think when you're under .002 it becomes damn tough to see differences unless maybe you get to around .0004 where I think the Elite is at?

David M. measured the UK VT65 at .000875 so if that holds true for the VT60, I would think the ZT60 would be a bit lower so both should be pretty close I would think, but we'll see.

Some state it was causing floating blacks and issues with color not looking as natural.

My ST30 measures around .005 and it's not cutting it for me...

I dont think anyone went into details except to say there were some issues when calibrating with it on, so they calibrated with it off an users could turn it on if they chose afterwords. It may have been due to the stability. According to the report from Robert however that the firware did fix the anomolies that were caused with it on, we wont really know howeer until it makes it out into the wild, OR we get a report from Kevin who was there when the new unreleased firmware was loaded....
Ken Ross's Avatar Ken Ross 09:18 PM 04-26-2013
Kevin liked it on. In fact I can't recall seeing any owner leaving the Optimizer off, so I guess if there are any ill-effects for them, they're pretty minor. smile.gif

I've personally seen absolutely no issues with it on in all of the 8500s I've seen thus far.

I wouldnt doubt that it hits that number, on a full black screen, but the "real" test I guess would be ANSI or the MLL test that is put up in the Calibration forum. We dont watch all black screens so the Full black MLL means little if it doesnt hold when content is on the screen (this goes for all companies).....
Ken Ross's Avatar Ken Ross 09:22 PM 04-26-2013
Based on what I saw at the show, I'm not so sure the ZT60 will achieve the Kuro MLL either. To my eye there was no question the Kuro was just a bit darker but with the all too common red tinge.

Not a lot to go on, but here are some measurements I've seen.

David Katzmaier, in cinema mode with low panel brightness:

55ST60: 56 fL window pattern, 13 fL full-field
50S60: 58 fL window pattern, 11 fL full-field

Chad B, in THX and custom modes with mid panel brightness:
50GT50: 33.3 fL ANSI, ~21 fL full-field
50ST60: 32.48 fL ANSI, 18.47 fL full-field

D-Nice, in custom mode with mid panel brightness:
ST60: 15.7 fL full-field

samsung has some limitations vertically, but neither one has any problem horizontally. imo the skewed view of the screen is a problem long long before the picture starts looking bad. i didn't think the samsung was going to be an issue, but if you are very close and have the tv a foot above or below eye level it will ruin the image. i had to sit down or stand at least 10-12ft back in order to view the tv in the store.

one of two ways to take it, either the speakers will be exactly the same, or if i'm not mistaken the VT has a larger bezel to house slightly more substantial speakers and perhaps the zt will have a thinner bezel? i just don't understand who spend 3k plus on a tv without some kind of audio system to go with it? i guess we're not quite there yet but soundbars are pretty easy to get, i wouldn't mind seeing speakerless displays for a few bux less, or a slimmer design.

something i've wondered, not being familiar with how the magic works, but why the heck can manufacturers not match what should be obsolete technology? you'd think at the very least matching 5yr old technology would be easy to copy. what has changed in the last 5yrs that stops panasonic from using the kuro technology (they own it now don't they?). i just find it bizarre to think a technology could get worse over time. so what's the hang up? cost? efficiency? some patents that weren't purchased?

It showed both were capable of showing similar detail, in spite of all the remarks about the "extra" sharpness exhibited by the F8500 and the other insinuations about the dullness of plasma before the king (F8500) arrived.

This makes David McKenzie's findings in relation to the VT60 all the more perplexing, though perhaps the ANSI checkerboard pattern (dipping only to 0.002 fL) is where the Panasonic's weakness in relation to the Kuro is manifesting. The shootout will resolve this and so much more.

I know. I'm equally as befuddled. THat's why I was hoping it had no speakers whatsoever, as I look down upon anyone who would even consider using integrated speakers, in any circumstance, for any reason. These people & their choices, they anger me.

I was under the impression the f8500 mll increased more than the panasonics when not on black screens. Though I don't recall the measurements at the moment

Kevin Miller:
60F8500: ANSI with Black Optimizer on: 24 fL / 0.003 fL (8,000:1)
64F8500: ANSI with Black Optimizer on: 34 fL / 0.004 fL (8,500:1)
64F8500: ANSI with Black Optimizer off: 34 fL / 0.005 fL (6,800:1)

Chad B:
64F8500: ANSI with Black Optimizer on: 34.95 fL / 0.0047 fL (7,436:1)
64F8500: ANSI with Black Optimizer off: 38.62 fL / 0.0064 fL (6,034:1)
50ST60: ANSI: 32.48 fL / 0.0029 fL (11,200:1)

It's interesting that Miller measured ANSI white so much lower on the 60" than the 64". I'm still dying to see measurements of the 51". The only one that I have seen with my own eyes is the 64" (which was impressive). But considering Samsung's plasma history, there is no way I'd buy a pricey 51F8500 without seeing some measurements on that first, regardless of how the 64" looks or measures.

D-Nice, in custom mode with mid panel brightness:

That's weird that the brightness would have actually dropped, but who knows? Maybe a tradeoff with some of the Panasonic models to eek out a bit more on the low end?

Hopefully the ZT doesn't make that sacrifice. Interestingly, at the Panasonic show, they didn't set up the demo to tout the brightness of the ZT despite the literature indicating they've improved brightness.

Hopefully the shootout will answer that question.

I don't believe that 2 screenshots taken by two different posters, with two different cameras with different settings, lenses and qualities, can reveal anything at all about comparable resolution or apparent sharpness.

This has been discussed on AVS for as long as I've been on AVS. Posted pictures are fun, but any attempt to draw PQ conclusions from them is likely to be destined for failure.

But I can tell you having owned a Pro 151, the 8500's sharpness is greater IMO.

Honestly, I didn't like the Samsung very much , the reds were pinkish and the shadow detail was no contest against the Panny. I found the black level very similar, though.
Unless you watch TV on a bright room, I can't even see a reason to consider the 8500.
Magnolia guys confirmed the ZT for mid June.

My magnolia is saying they're getting the zt on may 12-13.

That would be great. Just a couple of days after the shootout

I saw the VT60 and the Samsung F8500 in the same room and watched them for quite a while. The Panasonic had somewhat blacker blacks, but other than that they were fairly even in everything else. They both had great color, contrast. I like the looks of the Samsung much better (I'm talking about the bezel and stand) so I would pick it over the Panasonic. I don't think you could go wrong with either one, IMHO.

Sorry, I read this wrong and thought it was between the Panasonic VT60 or the Samsung F8500. I guess it's too early yet, not enough coffee. eek.gif

I think Panasonic hit a homerun with their stand. it looks great, and to me Samsung fubared it up. it's just to wide, and limits your options. of course if you mount it on the wall like myself everything becomes null and void.

You may think I'm not objective, you may think I'm blind to these issues, but you'd be very very wrong.

Man does this get tiring. rolleyes.gif

Having had the 64" f8500 in my home for ~25 days or so, I would say that unless you guys were viewing the tvs in a dark room environment, it would be hard to see the black fluctuations. They are subtle but annoying in a dark room. I know that I wasn't able to over look it once I knew it was there. I sent mine back to amazon and ordered another one through bb. Based on some other issues I had I'm hoping that I had a defective set. If the new one has the same issues ill wait for the zt, which I'm told my bb will have on may 12-13, and might swap if that sets picture is observably "better to my eyes".

Id also wait to see if the firmware that is coming out fixes thsoe issues......The firmware is specifically for "pops" and fluctuations.....
