Official Panasonic GT50 Series Discussion Thread [No Street Price Talk] - Page 97

Relax, its all good If you were happy with plasma before, you will be even happier with this new set. I can't comment about the quality of DirecTV but if you didn't see obvious flaws before you won't see them now either. Your new set is about 20% bigger. So take a close look at what you have now then move closer by 20%. This will give you the same apparent magnification you are going to get with the new set from your normal viewing position. So if your sit'n 15 feet back now just take 2 steps forward.

Every model has a slightly different character. Most folks are very happy with the new Panasonics so unless your personal taste is way off main-stream, you will more than likely be pleased also.

Worst case, send it back

The 58/65" had a lower black level than the 54 and smaller so there should be less of a difference there in your case than mine. The final rise is set to occur at around 500 hours on the 2009's so you are most likely past that point.

I do hope you are correct. I certainly can't see a difference from out of the box.

Are you an electrical engineer? Apparently not since you seem to have never heard of a ground-incuced hum among other electrical noises such as RF and EMI. I am not an EE myself, but I know that ferrite magnet chokes are recognized for their high frequency cancellation value. The term "electrical noise" was intended to refer to the gamut of noise-inducing interference often found (RMI, EMI) in electrical lines, from electric motors or distant lightning strikes, or even fluorescent ballasts, all of which can be audible under certain circumstances. Regardless, I think it is safe to say that Panasonic and other manufacturers know better than you or I in their decision to provide ferrite chokes to their customers. I myself have heard and seen the benefit of such devices. I am not trying to sell any device or product here (unlike you) but just wanted to offer some advice from my own experience. Sorry if it interfered with your ongoing attempts to be the resident expert here.

I recorded the 3D version of the Olympics opening during the night, which is delayed by several hours more than what could be viewed last night on NBC and is shown on a special channel. I watched some of it this morning and while it was cool watching it in 3D it really did not add that much to the show. I decided to switch the TV to 2D and discovered that instead of one normal picture I got two identical side-by-side panels with distorted pictures.

Is this how it is supposed to work? If you want it in 2D you have to view and record it on a normal channel.

Hmmmmm what did you record it with ? Does the recording device know what to do with the 3D signal ?

My guess is probably yes. If this was a 3D only signal and not a situation where both a 2D and 3D signal are provided giving you a choice, then you would have to make that choice by switching to the "normal" broadcast channel.

My second guess is that they did this in order to provide a full bandwidth picture on the "normal" channel rather than dumbing it down to also squeeze the 3D signal into the same pipe. This isn't a case where the 3D is being created from the 2D signal inside the TV. They are actually providing a separate 3D signal with both of the stereoscopic "fields".

I don't even want to make a third guess about how your recorder handles this but if the TV displays it as 3D then the recorder is doing just fine.

All of what I have read is from people going from 2D to 3D, you may very well be the first person to ever want to take a 3D image and flatten it . It may be a violation of quantum mechanics to even try; Albert is rolling over right now. Maybe string theory has the answer.

But seriously, I think you will need to record both channels if you want to watch both 2D and 3D. There may be some way to watch only the left or right image full screen but the quality won't be as good as the full frame rate 2D picture.


If I'm wrong about any of this then I deny all or part of what I said

Correct, but Ouch ! You don't own FaceBook stock by chance, do you ?

I will 100% confirm that my HVAC system will no longer function without a choke on the thermostat control line. The EM pulse from blower start-up current resets the electronic thermostat every time. The choke eats the charge and it works fine. I can't provide a first hand AV example, but in general, chokes do work.

I recorded the program via my DVR, Scientific Atlanta 8300HD. (I had doubts that the DVR could record and playback 3D but several days ago CableVision assured me it could and that it would not occupy more hard-drive space than a normal HD program. I found that they were correct.) The very-delayed broadcast on Channel 1300 was promoted and mainly sponsored by Panasonic, apparently to promote 3D TVs. I also had the option of recording the 2D broadcast on the regular NBC channel at the same time as it was broadcast in my time zone.

The bottom line is that you are correct, if I want both ways I need to record it both ways.

Now I wonder how it works with a Blu-ray movie. If you buy a 3D version movie for your child and then discover you don't have enough 3D eyeglasses for her and all of her friends, can you play it in 2D and have it look OK?

I'll let this to someone who knows for sure, but I know I have seen movie "multi-pack" titles listed as having BluRay, BluRay 3D, and DVD in the same box. Some have single flavor, some have two flavors, and some have all 3. So for your case, you may want to look for these multi-flavor combo's that give you a choice.

Have had the 60GT50 for a couple months now. Just got around to hook up the RCA audio out adapter for my turtle beach headset that I use when playing xbox. For some reason, I cant get the sound to output via the adapter to the rca jacks. I have never used one of these but the back of the tv is labeled pretty straight forward and the adapter jack can only go in 1 way and i was sure to connect just red and white. I looked in the menu but dont see any setting to enable the jacks (didn't think there would be one in there but looked anyways). Any thoughts? Defective adapter or component?

The headset work on 2 other TVs

Thanks

Yep. I went through 3 sets so far (all 60GT50s) and they all buzzed the same. I would tell you to swap it again just to make sure but in all likelihood it'll be the same. Learn to live with it if you can. Personally I tried but couldn't and my third set went back. Some of us seem to be more sensitive to the buzzing frequency than others. From my experience so far, it seems this year's Panasonics buzz much more than my previous three panasonic plasmas I've owned which is unfortunately as there aren't many TVs out there with equivalent PQ, save for the astronomically priced Elites and HX929s.

I have struggled to use my wireless headphones for years because many TVs will only allow analog audio out put if you use the TV's menu to turn off the built-in speakers, which is of no help when I watch TV with my wife. The solution is to use the optical digital output, which is always on. I run that output into a GefenTV Digital Audio Decoder, GTV-DD-3-AA. The output is left and right analog output that I connect to my wireless headphone transmitter. This way the audio from my TV is always available, even when the volume setting is turned all the way down, as when my wife is sleeping. In the past I had used the audio output from the cable box or DVD player, but that required a switch and extra cables.

the RCA jacks are Inputs. To output sound you have to hook up to the optic or hdmi/arc port.

The cable and satellite systems use a reduced resolution format for 3D that works with regular 2D bandwidth available on those systems.
The Olympics 3D HD feed appears to be 1080i HD side-by-side 3D format on my cable system.
They simply use a regular 1080i HD signal but put the left and right separate images side-by side, so each is effectively half the horizontal resolution or 960x1080.
The 3D TV recognizes this format and displays it in the TV's 3D format, for Panasonic plasmas thats the active 3D format where each eye's image is displayed full screen (scaled up to 1920x1080) for 1/120 sec and then the other eye's image is displayed alternately.

My cable system also provides several 3D on-demand titles, many are free, but in a lower 720p over/under 3D format, where one half image is on top and the other on the bottom in the same frame. Again the 3D TV recognizes this format and switches into 3D mode. But each half-image is effectively only 1280x360 resolution in that format.

Blu-Ray 3D discs however use a different full resolution 3D format that requires a higher bandwidth since it provides full 1920x1080 images for each eye, so effectively twice the rate of 2D 1080p video. This higher bandwidth requirement for full resolution 3D may require better HDMI cables and a newer 3D capable HDMI receiver (if used with a 3D bluray player) too.
A special 3D blu-ray player is required to playback in 3D.

3D blu-ray discs are formatted in such a way they are compatible with and can be played on regular 2D blu-ray players, it will just play in regular 2D in that case - just uses one of the two half images.
3D blu-ray players also can select to play a 3D title in 3D or 2D, my own Panasonic 3D blu-ray player I have setup so it asks you which to use (3D or 2D) at the start of playing a 3D blu-ray disc. Also many 3D blu-ray discs offer the 3D vs 2D choice in the regular disc playback menu system when you select Play Movie.

I don't understand how you are trying to connect a headset to the TV?
The component adaptor you show is for the opposite, its a video/audio input to the TV not an output, its for like connecting a VCR to the TV not a headset.
The only audio output from the TV is the digital audio (optical) port, unfortunately the newer TVs don't provide and older analog audio output via RCA or 3.5mm headphone connectors anymore.
There are digital/optical audio to stereo RCA converters sold, but the lower cost models (~$20)only support stereo PCM digital audio input format, not the dolby digital format that TV channels typically use.
However there is a model (~$80) that supports full dolby digital input and outputs to stereo RCA analog jacks: the GefenTV Digital Audio Decoder, model GTV-DD-2-AA

Some have also posted success in using a wireless bluetooth headset with the 2012 Panasonic TVs since they support bluetooth.

Here's a chart that will give you a graphical image, yours will correspond to the blue dots in the lower picture. These are forum member measurements. I'm sure it still looks good.

Forgive me if this has been discussed already, but is anyone familiar with the picture artifact that is occurring on my 55GT50? As shown in the picture, there are horizontal stripes stretching across the screen where text or light colored boxes are located. The stripes are most visible on light colored, solid backgrounds. Under normal viewing circumstances, the stripes are not noticeable, but under certain conditions they are particularly annoying.

Thanks for the answer. I'm coming off of owning a green blob plagued Sony SXRD projection TV, so I am familiar with all of the issues inherent to that technology, but much less so with plasma.

Thanks everyone for the replies. I get the dunce of the day award When I hook up the headsets on my other tv, its an RCA out, which feeds to a small wireless converter that sends the sugnal to the wireless headset. I will have to hook up via my surround system when i get that up. Thanks again.

The picture on my 50GT50 is outstanding. But when we watched the opening ceremonies in 3D my wife commented that when we saw it the previous night the picture in 2D the picture was also excellent.

When I compared the specs of Panasonic TVs I came to the conclusion that if you want excellent PQ you need to buy their 3D TVs and consider the 3D feature as an "added plus." At some point we may get TV programs where 3D makes a difference. I suspect it only makes a difference if consideration of 3D is part of the original concept, as with Avatar and Hugo. Of course I may find I am wrong when I will be able to watch live sporting events in 3D.

Man, I don't see anything either....and I'm pretty particular....

No disrespect meant here but the line bleed is 100% obvious in that picture. Either you don't know what to look for or your computer's screen isn't very clear.

@OP, don't worry. Line bleed is common with Plasmas. You can Google it and find information in regards to the technology.

Nobody has commented on the 4 vertical lines at the left edge of the screen. What causes that?

I think you inadvertently jumped into an exchange that's not related to "line bleed". In fact the exchange you chose to participate in started with post #2841 over two days and 14 hours ago.

See the picture in question below.

Vertical blinds.

For real though, look closely.

Ah, I thought people were commenting on the picture in post # 2897. Sorry. I think you're a few thousand posts ahead of yourself. There is no such post # 21841.

Sorry, should've used multi-quote. I have no idea where those lines came from, I have this TV and have never seen anything like that.

does anyone really know what cause the "plasma buzz"

They were. Just not in the post that you replied to. It is Post #2841
