Actually, 'fill' even on SD content merely does a linear stretch to fill the 16:9 aspect of the screen. 'Just' as far as I have read does a 'calculated' stretch to fill the 16:9 aspect. Exactly HOW it stretches though, I don't know. This is pretty much the same with HD as well. 'Just' in HD ends up losing some horizontal resolution in the process. I've yet to try it though with 4:3 content broadcasted with black bars.

STANDARD 4:3 PICTURE:
FULL - STRETCHES THE WHOLE PICTURE TO FILL THE SCREEN
A circle in the center of the screen becomes oblong
(People in the center of the screen become fatter)

JUST - STRETCHES EACH SIDE OF THE PICTURE TO FILL THE SCREEN
A circle in the center of the screen remains a perfect circle
(People in the center of the screen remain the correct size)

H-FILL - SAME AS "FULL" EXCEPT THE SIDE EDGES ARE CUT OFF

FULL is recommended for anamorphic picture
ZOOM is recommended for letter box picture

Sorry if this is a dumb question, but what exactly is an anamorphic picture?

Even though the PX80 series are 720 sets, both the 42" and 50" can accept 1080p inputs. The input is then scaled to match exact resolution of tv. I believe they can accept 1080p because their internal processor upscales all resolution to 1080p before scaling it down to 720p.

As far as I know, this is fairly unique among 720p sets able to accept 1080p input.

ah thanks, yeah that must be why i assumed that. shouldn't assume.

I have been a "lurker" for a long time - anyways - I'll get right to it. I got my 42px80u today, along with a tilting wall mount. I can't seem to find out how to attach the vertical brackets to the tv - what am i missing here? I popped off the plastic caps in the four locations that seem like logical mounting spots, but they have plastic inserts in them and the long screws supplied with the tv are not long enough to do anything. I am pretty savvy with this kind of stuff, but this one has me stumped. thanks in advance.

Just a little info on my 50px80u the first tv i purchased was a 40 inch 1080p sony and I quickly returned it realizing it was to small but in the mean time my xbox 360 was still set to 1080p so when I hooked up my 50px80u to my 360 I would get a black screen and had to hook up compsite in order to see the menu to change it to 1080i or 720p so at least in my case xbox 360 at 1080p=black screen audio only for the 50px80u. Just a side note the picture on the 50px80u looked better imo than the $1700 sony w3000.

At the end of the game apparently there is this large implosion of a galaxy? At the end of the implosion the screen goes blank, then the TV shut off and he couldn't to turn on for 10 mins - when it did turn on he saw something that refered to default settings? But I checked out everything the next evening when he told me about this and all the settings are where they should be picture is perfect as always. I wonder if this part of this particular game when it ends or something went kapow in the tv?

Update: I checked the power cord on the back of the set to see if it was properly seated, put a little pressure on it and got a tiny 'click'. Looks like this may have been the issue. Will keep my fingers crossed. Also after 3 1/2 weeks it appears to me that the PQ just keeps improving!

Sounds like you might just need longer screws.

I've then set the PDP to display in "Full" mode for HD signals and in "Just" mode for SD signals. I think that's the best use of the screen formats with the least amount of stretching. I could be wrong though. With so many potential combinations it gets a bit confusing.

That's what I do. Seems like the only drawback is the slow channel switching (all the flashing before the image stabilizes), but since I watch most things from the recorded list, this doesn't bother me to too much.

One other problem has nothing to do with the TV or receiver. There are some offending channels out there that broadcast a lot of 4:3 stuff on the HD stream with black bars on the side. And there is some programming (particularly worse with commercials) where there are black bars on all 4 sides. The worst offender is the channel that shows a 4:3 program that is already letterboxed, then stretch it to fill 16:9, so now I have the worst of both worlds - distorted images with black bars top and bottom.

I can never get this straight. Does it make a difference whether the hd source like hddvd or bluray is set to 1080p or 720p or 1080i. It seems like it gets processed one way or the other. I have yet to determine which setting uses less processing. By eye it's kind of hard to remember which setting looks best to switch back and forth. Is there any difference in quality which way it is set? Can you (general public) tell? Thanks.
post #1662 of 5765
Played some GTA IV on my ps3 last night and it looked great. Contrast was very good. Easy on the eyes did not have to strain to see things and I just used my same cinema settings I use for regular TV watching. Very pleased.

The panny does not accept 1080p via component...thats why you got a black screen.

(Btw, you coudl've just flipped the HDTV switch to SD and it automatically defaults it to 480i).
post #1664 of 5765
Just got my 50x80u last night from sears. Decided to pay a little more than EPP, but was able to use gift cards and save about $200 on gas. I figure I am ahead. Anyway, I hope to have it up and running by tomorrow so I can watch the Red Wings. Does anyone recommend a specifice surge protector or a min. joule level? I know it may seem like a basic question, but this is the first HD tv and wasn't really worried about the old one. Thanks to all that share here.
post #1665 of 5765
APC makes decent ones for cheap. I have the apc pf11vt3, and you can get it off of amazon for under $30. Someday i may buy a filtering surge protector, but i think differences are slim for price value. Let your wallet decide. I know furman is a decent pro filtering choice.
post #1666 of 5765
I just use something like this:

Fits behind the TV on the receptacle that I installed there.

In SD mode, "full" will show the content in 4:3 format (black bars on left/right of screen); "just" is a lot like "h-fill", where it performs a horizontal stretch of the SD content to fill the 16x9 screen screen, but it will make it look less stretched (justifying the picture). On HD content I always use "full" because this is how the content is supposed to be viewed. If you are watching something with black bars on the top/bottom of the screen and want to get rid of it, you have to use "zoom" to get rid of these bars, which zooms the entire picture to fill the screen (evenly stretching vertically and horizontally, but it cuts off the picture all around at the same time).

I was told and believe FULL is the correct aspect ratio for 16/9 HD only. Push the INFO button, if you see 1080 or 720, use FULL. Unless the source is showing a 4/3 ratio, then use JUST or ZOOM.
post #1668 of 5765
I have my cable set to only output 1080i or 720p, so my findings likely differ from those who have it set up differently. Again, I am no expert with aspect ratios.

I believe that would be a 16:9 ratio image.

Yeah, I hate that. For those cases, I will usually just switch to the network's SD channel. It's generally a pretty rare occurance and I think most of that actual content isn't HD anyway.

For anyone who cares to read professional reviews, CNET has posted their review of the 42PX80u:
http://reviews.cnet.com/flat-panel-t...Search+Results
post #1671 of 5765
It appears that the tv got docked big-time because of it's inefficiency in removing noise and color accuracy. The rest of the article is quite favorable (best blacks in its class, better anti-reflection filter than the pz85u - even though they looked the same to me). Interesting that it is rated far lower than previous years models (42px50u, 42px60u and 42px77u/50px77u - not sure why they loved the anti-glare screen of the px77u so much, I couldn't stand it). Noise reduction must affect the score greatly.

CNET's settings are very surprising (or I guess not so surprising since they used Custom as their favorite setting for the pz85u as well...I find Custom as a bit noisy myself).

I've totally lost faith in CNET reviews in the last year, whether it's phones, TVs or speakers. Often you'll see this reflected in huge discrepancies between user ratings (with large enough sample size) and their in-house rating.

I don't know why they insist on testing TV's in custom mode when the best measured gamma is often cinema mode, not to mention that changes the behavior of the color decoder (see PZ80/85 thread). Then they go and complain about the gamma on the TV.

As with noise, I'll repeat what was said in the PZ80/85 thread. Why do you need noise reduction if you feed it a good clean digital source with little noise to begin with? And since custom tends to be on the noisy side (as with standard), how can you evaluate a TV's noise reduction setting on its ability to remove noise that it put there in the first place?

And they continue to make big statements about black level without actually publishing any numbers whatsoever.

I'm not feeling defensive about the fact that this is an entry level TV - you get a bit of what you pay for. But I hate that the most visited website for reviews is publishing such unscientific crap.

post #1673 of 5765
To be honest, after the absorbing so much HDTV information in an effort to purchase my first flat panel HDTV, this review was somewhat validating. Until you get into the particulars where CNET tends to pick at things that I probably would never notice, the review was quite positive in summary. My PX80 arrived this morning and this review makes me even more excited to fire it up. Even the review says at this price point, the Panny's are very tough to beat.

I do agree that CNET should be testing these in real world conditions, not optimum conditions which most people won't ever achieve in their living rooms.

I remember seeing information regarding break in for plasma's and I can't seem to locate this particular suggested method. I believe it was using a white test pattern from DVE and keep it on for 2 hours, then off for 2 hours, then on for 4 hours, then off for 4 hours, etc. I believe it was a similar method to this. Does anyone have a link to these instructions or suggest another good break-in method? Thanks.

I do like the C-net settings. Brighter than the prevailing Cinema-based settings on the thread, and I like the greens better, which had been bothering me. I guess it was gratifying to hear about the greens in the review. The C-Net settings do seem to push the reds, though. I just tried the settings and toggled back and forth a few times, so not a definitive assessment based on varied, long-term viewing yet.

Check the sticky at the top of this forum.

However, it is the opinion of many, myself included, that current generation PDPs do not need a specific break-in routine. I set mine up using Larry's suggestions right out of the box and it has been great. No problems in nearly a month of ownership.
post #1678 of 5765
Played my first video game with my 360 hooked up to the new TV. All I can say is WOW, what an incredible picture! I played a game of Madden 08' and coming from a SD 4:3 TV, it's a whole new game.

I fear my kids will never leave the basement now!!!
post #1679 of 5765
I see most of you have the video noise filters turned off in your settings. Any specific reason why?

The only complaint I have of this TV (and it's a mild one), is if you sit close enough (5-7 ft), many background scenes do tend to get "grainy", but certainly not something worth focusing on. I almost went with the 1080P set in hopes of eliminating this issue, but I doubt that would have helped much since most broadcast TV isn't in 1080 anyway.

Overall I am very happy with the PX80 and would definitely recommend it.
post #1680 of 5765
Well.... I just got out my colorimeter and looked at the Custom mode on my 42PX80U. There is no way that CNET spent more than a few minutes with instruments on their test unit. They said it "went exceedingly quickly" -- apparently so quickly that they didn't even check all the Picture modes.

My measurements verify CNET's RGB color accuracy numbers and color temperatures almost exactly. However, and it is a big however, the gamma of the Custom mode that they used for their review has a very weird shape with an average value of 1.8. On the other hand, the gamma of the Cinema mode on my set is 2.25 with a close to perfect shape. (2.22 is considered the desired gamma value.)

Just passing this on for general information.

Larry
