post #4771 of 9713
I saw some GT50 owner comments on Amazon that indicated that the THX modes disable the pixel orbiter function (is that correct)? I'm wondering if that might be the reason there is so much variation in owner experience regarding Image Retention (IR)? I'm considering moving from 5-year old Samsung LCD to the GT50 for improved PQ for Blu-rays, but need to be able to watch Dish HD sports (e.g. NASCAR) with logos and ticker tapes for extended periods in a moderately bright room. So, maybe I could use the THX cinema mode for Blu-ray, and create a custom mode similar to THX bright room but enable the pixel orbiter function, for DISH HD, to avoid IR?

Hi,
my GT50 (awesome TV) is connected to a Yamaha RX-V671 by HDMI with HDMI control enable and ARC.
Despite having this activated in the Yamaha menu, I need to disable/enable HDMI control each time I switch my system ON in order to get it working. If I'm not doing this, I don't get any sound thru my HT system.
Anyone experiencing similar problems?
Any clue on how to solve it?

Unless I get this solved, I'm planning to buy an optical cable to get the TV sound back to the receiver.
However, will be less easy with 2 remotes.

Thx in advance for any help!
post #4773 of 9713
And another question:
I have a NAS containing videos, the RX-671 and the GT50.

Question: how to upscale videos to full HD?
I mean, I'm using the GT50 as media player getting videos on the NAS but they should get upscaled by the receiver... Unless there is an upscaling function in the GT50?

Thx!

That's what I do.

The pixel orbiter is pointless and serves no real purpose.

In a 4:3 setting, probably not. But if you're watching FULL screen, I believe it does help with those channels that have the annoying logos. The PO slowly shifts the picture around at a rate undetectable by the eye. One of the reasons for the black border around the outside of the panel, so the picture can shift around slowly.

Not sure why you wouldn't use the PO. You can't tell it's on or working and it can only help reduce IR, this is why the Panny engineers put that capability in the sets.

It does not move enough to have any effect on IR or burn-in whatsoever, beyond slightly smearing the edges of it. If the placebo effect of the pixel orbiter helps however, good.

Can you explain how you know this as fact, why would they implement this feature if it is useless? I use it and havn't experienced IR. But then I havn't tried my new TV without it on, so maybe it is useless?

Simple common sense.

They include the feature to ease the irrational fears of those who have been misled about plasma display tech.

Explain why you think that wiggling a big Channel 7 Logo up/right/down/left by only a few pixels worth of movement does anything to erase out the bulk of the logo?

It only blurs the absolute edge of the logo's afer-image so the most it would do is soften the edges of that logo, but does nothing to remove the bulk of the logo. And a lot of people see their image "wiggling" around when the PO is enabled and that bothers them so they just leave it off.

The PO is basically a Placebo, added to the menu after customer complaints that Samsung has similar anti-image-retention settings so why doesn't Panasonic.

True, but to me it makes it a little less noticeable with the blurred edges. As my panel has aged, I'm getting IR much less often and for a shorter duration when it does occur.

Well maybe 1% less noticeable, but it leaves about 99% of the logo unchanged.

Same here, even though my Pixel Orbiter has been off since i bought the TV back in early July.

I love the picture on my new 60GT50, and have no problems at all with buzzing or any other "look for trouble" OCD tendencies (starting at slides to look for dead pixels).

However, I still can't get the TV to sit level on the stand. Even though the screws are actually screwed tight, there's still somehow, play within the stands movement - meaning I can walk up to the TV, and while the stand is held down, you can tilt the TV to a more level position - even though it's screwed to the stand. This makes no sense whatsoever to me, and is actually causing a great deal of anxiety, especially with something this expensive.

A few years ago when I received my 46pz800u, we put it on the stand, and that was that. It was level. Why this one wouldn't be drives me absolutely insane. Is the top of the pocket on the TV (the one that accepts the insertion of the stand) not smooth, or uneven? Why would this even happen, but more importantly how am I supposed to fix this? I held the TV to a level position while a friend screwed the 4 screws that "secure" the stand to the panel, but even when the screws are in, it doesn't stay.

I have no buzzing or any other problems as I stated, so I'm completely unwilling to return this TV for a problem of this sort. Obviously if it's mounted on the wall, this is a non-issue - problem being I'm renting an apartment and am not allowed to make "adjustments" to the property, nor do I want to spend any money on a wall-mount just because quality control or engineering didn't do their job.

How could their be any play whatsoever with the vertical tilt when the screws are tightened to the panel? When you're looking at the screw holes, it doesn't even look like they attach to anything, because it looks like they just go through the hole on the stand. I hate that I find myself typing paragraphs on a Sunday evening about this stupid, stupid issue.

I love the picture quality of the GT50 but I'm sorry to say it must be returned. My mom was watching CNN's live coverage of the CT middle school shooting which had no commercial breaks. Now there is a big LIVE CNN logo burned into the screen. This is the seconds logo burned into the screen and I've had it for less than two weeks. I already made a post about the first image burned in a few posts back.

I hate to go the LCD route but that's the only way I can watch TV and not be paranoid. If I were to have a dedicated home theater just for movies than yes, plasma would be the way to go but there are just too many high contrast logos.

Well, Chad B just left a while ago after calibrating my new 50 GT 50 and I'm really impressed. I thought I really had it dialed in pretty well and the picture was in my opinion very good but after Chad was finished with it there was a noticable difference, the blacks were better, the whites were much better and well as the colors. He was very courteous and explained what he was doing as he progressed. Many times he would say this is how it was and this is how it is now. and then show me. One of his favorite things to do as he was moving along was to show a woman talking to a man and show me now and then how it was. Quite a change. The ladies face was very detailed and the color was pure. It was a pleasant experience and he is a fine fellow. Certainly was money well spent.

This sucks, is PLASMA just not capable for conventional daily viewing material without experiencing these other problems?

I'm considering a TC-P55GT50 and was wanting recommendations on a wall mount. I don't need anything fancy...just standard low profile mount. Are the monoprice options a good way to go or do I need to look at something else? Should I really consider a wall mount with tilt and swivel? I've never done a wall mount before.


Thanks for the responses.

Yes it is. Problem are few and far between. They usually only occur after several hours of the same static images being displayed. A poor choice of settings can contribute as well.

This was my first wall mount as well. I'm completely happy with the one I got from Monoprice.

Thanks for your calibration report. I've included it in the flat panel (Post #2) lists that are linked in the signature area at the bottom of my post. Enjoy. smile.gif

Happy to report the 2nd 65GT50 is quiet - even when shutting down the XBOX using HDMI-4. This one shows a July2012 date on the back.

That's great to hear! And more proof that it's not normal for a 2012 Plasma TV to buzz from a normal viewing distance.

If you would, could you please post about this in the ST50 buzzing thread because there are people there who are insisting that hearing buzzing at 12 feet is normal and not the result of a defect. This may also help people with buzzers get theirs fixed despite some stupid repair technicians claiming the buzzing is normal and refusing to attempt repair, when it is in fact not normal.

You are absolutely right. Many of us have sets where we can only hear a buzz at the back of the TV with our ear very close to the set.

Is the pixel orbiter enabled?

What settings are being used?

I'm all about learning and trying to get the best possible picture...it's my first plasma. That being said, I did disable the PO today. The picture looks the same, should I expect a crisper picture?

I'm using Custom mode, with D-Nice's and CNET's settings. Using D-Nice's for the Contrast/Brightness, etc., but CNET on the Pro Settings. Did not run any slides, but used Standard mode for about 80-100 hours and then went to Custom mode. I also watch a variety of programming and stretch the screen if black bars are on the side (4:3) or top (widescreen movies).

I should disclose I have the 55ST50 though, not a GT, but I browse with GT and VT threads too.
post #4799 of 9713
I just picked up my new P50GT50 yesterday, and I have to say I love it after moving from LCD. I'm new to the whole Plasma thing, so I could use some help.

I did notice the picture does flicker a bit when there's lots of whites on the screen, but I think that may be normal for Plasma. I haven't done much calibration, so there may be a setting I'm missing here. I really would prefer not to return this set, but I do love it so far. I wasn't comfortable with Plasma at first, but the Best Buy salesman totally talked me into it, and it is really good. I haven't had any burn-in issues as of yet, though that could change at some point.

I also had trouble adjusting the aspect ratio so that absolutely nothing is trimmed off. I then figured out how to go into Pro settings, and chose HDTV2. It does seem to help, but at the moment when it is connecting to the Internet, I think there might still be about a mm of the picture trimmed.

What would you consider to be poor choice of settings?
Just so I can try to avoid it (on ST50) ...
