Hey Now no need for name calling....
post #8402 of 13478
Hello Fellas, I've got an annoying issue with my VT50 that I haven't seen talked about in this thread.


So, every time I fire up my Panasonic BDT220 Blu Ray player and 24 hz output engages, the VT 50 somehow changes its Picture Settings back to "Cinema". I have set up Custom picture settings that I use for everything else, cable, HTPC, etc. It's very odd, I can switch between my HTPC and Cable Box and the VT50 never does anything with the picture settings automatically, but as soon as a Blu Ray starts it's back to the crappy "Cinema" preset. FWIW, I'm using Input 1 on the TV and the HDMI 1 out on my Pio Elite SC-37.

Here's a weird example of it, if a Blu-Ray has a movie preview, I can change the settings back to custom during the middle of the preview, but as soon as the NEXT preview begins (ie once the set sees the new 24hz signal I'm guessing) the TV will default back to "Cinema" picture settings.


WHY IN THE HELL IS THE VT50 DOING ANYTHING AUTOMATICALLY WITH PICTURE SETTINGS??? Lol, it's so frustrating to constantly remember to change back to Custom settings. My GT30 was "set it and forget it".


I've tried turning Viera Link off everywhere, HDMI control is off in the SC-37, etc. I guess the only thing I haven't tried is using different in/outputs but there should be no need to do that.

I have a 55VT50, built in May 2012..

I would very much appreciate it if you guys could answer a question for me. If you take a look at the attached image, you'll see a series of roughly 2" gray bars going up the left side of the screen (just about the 7:31 in the score ticker at the bottom left). They're in sets of two, with a slightly larger gap in-between sets.

I first noticed this last Friday while watching Avatar in 3D (during a scene with a bright, one-color background). The next day, I noticed it during a hockey game on NHL network. So it's on multiple sources, and it's visible any time there's a bright, one color background.. It's not going away, so I'm thinking I need a service call, but I wanted to check with the video detectives first and see if you guys had any what might be causing this.

I'd run the image wiper function in the "Image Rentention" menu for a few hours and see what happens to the bars. If they're still there, it's definitely time for a service call.

The BDT-220 is doing this not the TV. My BDT-500 did it at first as well, drove me crazy. There's a setting on the player you need to toggle to change it, can't remember the name of it off hand. Check the manual.

Start with the scrolling bar wipe function, like previously said, if that does not work the Disney WoW blu ray disc has a Pixel flipper on it that works really good. I would let the pixel flipper run over night.

Hope you can get that resolved!

Thank you very much, I'll have to break out the manual tonight I guess. I did take a stroll through the menu settings but nothing jumped out at me.

Some of the settings this BD player sets as default are just mind boggling......

It wasn't obvious to me either.

If you use the THX Cinema or TXH Bright room, it disables the orbiter and changes HD Size to 2 so be careful with running your games with that especially right at first. I use Cinema for everything right now. Game mode disables most of the video processing so you get less lag between what your doing and what shows on the screen. It's pretty bright though so if you use it, might want to tone down the contrast a bit. I've had some logos on my screen for a couple hours and haven't noticed much IR

Thanks.

If I had to guess, I'd say it probably has something to do with Viera Link or the HDMI control settings if there is a menu for those.
post #8411 of 13478
You'd think one could just plug the blu ray player in and out would come unmolested HD 1080p/24 and HD audio....guess again lol.
post #8412 of 13478
Any luck with this? I've got the same problem. Sounds like there are different menu options by country, i guess.

Glad I caught this bit of info before the frustration began, I have a BDT-220 on the way and will need to remember this during setup. Thanks for the tip.

Guys, thanks for the advice. When I went to the Panasonic image retention screen, I noticed that the ESPN logo was very faintly visible in the lower right. Once I saw that, I realized that it's possible those bars are in the same place as ESPN's left-side "upcoming news" ticker. So maybe this is image retention instead of some kind of panel defect. I'm surprised, since we watch a wide variety of programming, but at least I can try your suggestions and see if the problem goes away.

I don't have it in front of me, but isnt there an option for 'HomeTheater'? That turns off the TV speakers and routes the sound out of ARC and the optical (though I think the optical is on all the time).
post #8417 of 13478
I have the opposite problem. My set is only an hour old, but I don't think that my receiver supports "return audio." I'm still researching ... I can't get my speakers to turn ON with Viera Connect.

I am SO HAPPY this TV has an MLS app! I about fell off my sofa! Makes life so much easier. I thought all these TV apps were pure crap but I'm really impressed.

Takes a lot of hassle out of watching MLS Live through HTPC. As long as I can get the audio...

Now onto image quality and all sorts of other things.
post #8418 of 13478
recently taken delivery of the TX65. 24 hrs later ...

mixed feelings.

while it can produce some of the most amazing images i've seen, it's got some pretty bad drawbacks. and i don't understand why. would really appreciate it if someone could offer me some insight.

1. black levels : everyone said they're REALLY good on this set. some of the best. but in my limited experience, this set can't do black. at all. not even close. dark grey, but not black. the perceived black levels are very good. when there's other lighter content on the screen, or when there is some light in the room, the blacks do look very deep and inky. but turn out the lights, watch a dark scene in a movie and ... bleh, it's like watching an LCD screen. dark gray !!!! what gives ? i'm on setting THX Cinema so this should be pretty close to what this set can achieve, yes ? OR ... have i completely misunderstood all these reviews, forum remarks and panasonics marketing. i thought deep blacks meant the set could actually do black. i thought that was the selling point of plasma as a technology. i had this naive idea that when this set got to a dark scene, the blacks would be so good that the whole room would darken out. which would be cool. but no. a nice dark gray screen i get instead. have a missed something here ?

2. motion : my LCD projector wasn't great at motion, but it was watchable. i really thought with plasma, motion would be improved. it actually seems worse. i know about motion judder with 24fps, but it seems exaggerated when watching blu-rays. i've tried both 24Hz, 60Hz. Interestingly, it doesn't seem as bad with netflix movies and tv content on DVD. so this set can do motion, but struggles badly with blu-ray - even taking into account of motion judder.

3. rainbows : WTF ? i thought this was a DLP thing. but i'm starting to see flashes of colours when i move my eyes around the screen. on the plus side, that should take my mind off the disappointing black levels and motion judder, eh ?

4. fans : a bit nosier than i would have liked, and there's TWO of them. although not annoying when watching tv so not a big problem. but can't understand why panasonic didn't add 2 large 120 mm ones and run them slower. it is possible to make almost silent fans in PCs.

in short, technology sucks. i'm feeling a bit down. and i think i'm entitled. i wasn't expecting this amount of trouble with a flagship product like this.

again, would appreciate if any input. could i have a faulty set ? do others get genuine blacks ? thanks.

I won't comment about #3 and #4, but I'll make two comments as another 'newbie' to the VT50:

a) You need to break the set in to get the colors to stabilize. Practically, that means 100 hours (or more) of full-screen, lower contrast viewing. You can research the settings thread and some posts over the last few pages to consider which levels you want to useboth during break-in and afterwards (I'm currently using the ISF night colors that were posted last week personally, as I've hit 100 hours). Also, to get the colors optimized, you might want to consider having the VT50 calibrated. In that case, you should consider downloading the D-Nice slides and running them during break-in, with the appropriate Custom settings.
b) Do you have the Motion Smoother setting off? You might want to try viewing with it set to off and compare how your content looks.
post #8420 of 13478
ANDYM - Don't know if this helps you and I know it's not relevant on the face of it but perhaps it's a lead. I found this on Cnet about Euro models -

"Beware customers, for no one mentions that there is a HUGE difference between the 55VT50B and the 55VT50E.

The second is the same TV meant for the European market, and believe it or not its panel brightness has been locked at around 65 cd/m2 in the professional mode - rendering this option completely useless!!! In the other factory modes, this TV is relatively okey, but only if you constantly keep switching the eco mode on or off depending if its night or day there. (during daytime you should turn it on, while in the evening turn it off)

I find it really really disgusting that Panasonic cripples this TV for the European market. The USA users can enjoy around 140 cd/m2 panel brightness in the professional mode, while we have do live with less then half of this.

I tell you it is completely useless for its way to dark for even a completely darkened room - or when its midnight - no matter.

In the end I had to stay with "normal" or "dynamic" mode, where colors cannot be fully caliblated (you have white balance option only) and there is NO way to calibrate gamme.

I am very disappointed Panasonic.

This TV could be the very best TV - but why did you have to ship this European model with cut back panel brightness????

Recommended for only those users who can live without calibrated panel, and can swallow the fact that for the same price we got to use a crippled product.

Unless Panasonic issues a firmware fix for this - I say stay away from this TV or get the USA model (55VT50B) and use that one."

Thanks to Turbe, I Just tried my hand at installing ControlCal ( for the VT50--North America) and loading ISFccc Day/Night settings on my VT50. biggrin.gif
post #8422 of 13478
If I am not in a rush to have a professional calibration, the safest way to watch the 65VT50 for the break-in period is to watch it in the THX Cinema mode? I've read through many posts of running slides, which I still might try once it arrives Friday. There is so much information, that the more I read the more I get nervous on what is correct vs incorrect while grasping 10 percent of the info. There must be others like me...lol. Also if anyone had there set calibrated and is within an hour of Dutchess County, NY I would love to see it....I will being the beer :-)

thanks for the feedback sdrucker.

i am thinking about getting this set calibrated. but my initial reaction was simply, do i have a faulty set ? i'm just not seeing those dark, inky blacks that everyone else seems to be getting. i hope things do improve over the next 100 hours and will definitely look into calibration.

i do have motion smoother setting off. tried it. it went off, straight away. the judder goes, but everyone moves around rather oddly on top of the SOE. it's rather bizarre to watch. i don't know how anyone could get used to this.

and thanks Glashub. i think i had read that post during my research period. but had forgotten about it. sounds like i have something to look forward to smile.gif

You need to look at some of the settings posted in this thread. To give you an idea, set panel brightness to mid, contrast to 85, brightness to 54, and gamma at 2.4 in the Custom setting. My blacks are extremely inky.

If you like watching with the lights off, consider buying a bias light from idealume. It's the best $70 you can spend. You will be amazed at how black the blacks are and how the image pops off the screen, and it also really lessens eye fatigue from lights off viewing.

Edit: Excuse me, just saw you're from the UK and using a different panel.

The Individual shows his location as the UK. He has the 65" VT50 I believe. He chose for his default THX Cinema which according to this review of the UK model is the way to go due to the Professional Modes there being exceedingly dim. Here is the review:

http://www.hdtvtest.co.uk/news/panasonic-tx-p65vt50b-201212152370.htm

Clearly something is very amiss here and the individual would be better served posting to hdtvtest's panasonic forum here: http://forums.hdtvtest.co.uk/index.php?topic=7051.0 where David Mackenzie himself will no doubt respond or on avforums.com.

I don't agree with that about UK's THX Picture Modes is the "way to go" - at least for reference viewing.. My opinion is based on feedback from Steve, few other Calibrators and VT50 owner/users of mine..

1)Here, 2)Here and 3)Here is info from another well respected and experienced Calibrator there (Steve Kemp).
Quote:
I can't agree with on certain things you say. It's all settings , there seems to be a lack of understanding of what a proper image should look like. The pro modes give accuracy that and the slightly elevated brightness levels are there for a good reason. Too many people think that black should look like the black hole of calcutter. Supposed to mimic a cinematic look and it does, with a wide but easy on the eye dynamic range.

~

If you want accuracy then a VT50 will deliver it.

With greyscale set correctly across the light spectrum the dynamic range is huge. You can't do this in either of the THX modes and can't touch gamma or colour and both are wrong. THX bright room is a joke. Colour is wrong, gamma is indescribable and it clips white to a stupid level.


However, I will email David with a link to my post here and ask him for his feedback....

To summarize what I said in my recent review of the TX-P65VT50, it depends what your priorities are - contrast or linearity.

The THX mode offers good accuracy (the oversaturated green has been noted) and excellent contrast performance.
The Professional mode offers excellent accuracy, at least once calibrated, but on the European version doesn't deliver the contrast performance I'd ideally like to see from a high end PDP.

It's very important that American readers remember this point: the European VT50 *does not have a "Panel Brightness" setting*. It is a different display to what's sold in the US.

Now I know from experience that on the US models, there are three panel brightness settings and only two of them are really useful ("High" just clips highlights). But, the European models are basically locked into a "Low" setting in the "Professional" modes (the ones that can be calibrated).

However, the Professional modes also give better low-level gradation, which I imagine is what Steve is referring to. They also give an elevated MLL (on the 65" version, roughly 0.0046 fL, versus the 0.002 fL we measured from the US version at the 2012 Shootout) in exchange for the more solid shadow detail. Peak white is lowered too; with a standard sized 100% white window I got just 65 cd/m2 (18.97 fL) out of the Professional mode on the European 65VT50.

That's where subjectivity plays a small part - which limitations can you tolerate more? 18.97 fL is just too dim for me and for most viewers. For reference viewing in a light treated studio environment these modes would probably be acceptable, but even then, 18.97fL is low even by monitoring standards. Most users who are installing European 65VT50s in their living rooms are likely to agree and choose the THX mode. It's a damn shame that it's not fully calibratable.

So, to summarize:

[Professional] modes:
10p White Balance
10p Gamma
3-axis CMS
Better low-level gradation
Poorer MLL, poorer peak luminance

[THX] mode (NOT "THX Bright Room"):
Better MLL, better peak luminance
Slightly noisier near-black details
Greyscale only adjustable in service mode (2 point)
No gamma or CMS adjustments at all without an external video processor

From what we can tell, it appears that Panasonic's engineers have access to a few different "under the surface" settings; a few different drive modes that balance gradation quality and contrast performance. I can't say without having one here to look at, but I would imagine that the American TC-P65VT50 has poorer low level gradation than the European version, but the higher contrast performance. The higher contrast is a much bigger deal, if you ask me. Of course, it is possible that Europe got the short end of the stick and the US version has both (high gradation and high contrast performance simultaneously). I don't know; it's a shame we weren't aware of more of intricacies back in May when I was at Value Electronics so I could have come home with some more answers.

Sadly, I've been locked out of AVForums.com due to forum politics, so can't answer questions there. Feel free to email me, or find me here on AVS or on the HDTVtest forum, though smile.gif

I've read through many posts of running slides, which I still might try once it arrives Friday. There is so much information, that the more I read the more I get nervous on what is correct vs incorrect while grasping 10 percent of the info. There must be others like me...lol. Also if anyone had there set calibrated and is within an hour of Dutchess County, NY I would love to see it....I will being the beer :-)

Do I need to break in a new plasma TV?

"The truth is, unless you plan on doing something abnormal with your TV right as you get it, you don't need to do anything special to break in a plasma. Just watch the thing. That's it. Watching regular content will age the TV perfectly well, and after 100 or 200 hours, the TV should be "broken in" plenty enough that you shouldn't have to think anything else about other than how awesome it is."

"What constitutes "abnormal?" Well, only watching 2.35:1 movies, only 4:3 TV shows, or only playing one video game would do it. In each of these cases, you're not using the entire screen equally. The black bars on 2.35:1 movies (top and bottom) and 4:3 TV shows (sides) aren't using those black phosphors. So the center image will burn in at a different rate, i.e. it will become slightly dimmer than where the black bars were. The trick? Don't watch only one aspect ratio. Yep, that simple. Watch some full-screen HD. Watch a DVD. Worst case, stretch out that TV or movie so it fills the screen (oh, the horror, I know). And again, this is just for the first month or so."
