All, Futureshop has this model on display, and as far as I can tell it is capable of displaying HD (LG's www site says it is "1080i, 720p HDTV compat."), yet the LG Canada www site describes this as a "42" EDTV Plasma Display Panel".

So, I'm a little confused. Is it an HD or ED display? Should I care? There is another LG plasma, same size, less $ (RU-42PX10), also described as EDTV.

Wondering also how these models stack up against Panny's TH42PA20? Thoughts?

Thanks.

Most EDTV plasmas can "accept" HD inputs (720P, 1080i), however, the signals are downconverted to 480P.

There is a significant difference between 480P and HD, however, I hear these 480P plasmas do quite a nice job on DVDs and SD.

Thanks, 57. That's where my confusion lies: I need to find out if this new LG model is downconverting to 480 when it receives the HD input from Cogeco's box. I believe that it does not downconvert (unlike the other model), but want to confirm. Some of this info. is often buried in the owner's manual. Must see if LG has a PDF.

These LGs are very attractively street-priced at the moment.

Page 46 of the owners manual states that it's 768 x 1024. The 768 part is the vertical "resolution" and is good (similar to 720P), but the horizontal part is 1024 and that's lacking a bit compared to most fixed pixel displays which are more like. 12-1400. If it's a good price, certainly worth considering.

As you can see, the 50" has the full 1366 horizontal.

Once again, many thanks! For the obsessive types like me, knowing whether a display is downrezzing is an important consideration in making a purchase decision, as well as seeing the pq from a DVD source. Perhaps the "average consumer" (if there is such a person) doesn't care, but spending several thousand hard-earned bucks should be based on as much info as possible. Can't remember when that level of spending was an impulse purchase for me!

HD is 1280 x 720 and/or 1920 x 1080. If your display ( a fixed pixel one like plasma) can not display this ,it's going to downrez, however you put it.

 

[57]

adit, please remember that there are a lot of "HDTVs" out there that cannot provide the horizontal resolution you mention.

For example, most direct view TVs have about 700-1000 lines of horizontal resolution. (There are some newer, very expensive units that do more, but they are rare, and as I said, expensive).

CRT-based RPTVs typically have about 1000-1200 lines of horizontal resolution. These are measured using a "signal generator". Don't believe the specs, until you read an independent test report on the TV.

An HDTV only has to be able to display either 720P or 1080i (no mention of horizontal resolution) to be called an HDTV.

Some very expensive plasmas have 1024 x 1024. I don't think I'd throw it out of the house if someone gave it to me..

I would not throw it either . But for a fixed pixel display ( LCD, Plasma...) I would like to have the "exact" number of pixels (and lines). Fortunately we are there already, Direct View LCD, LCOS and DLP had reached 1920 x1080. ( so this means in fact 1080p...) It's true, until the price gets lower I will stick to my CRT HDTV.

IDirect View LCD, LCOS and DLP had reached 1920 x1080. ( so this means in fact 1080p...)

Please provide me a link to LCDs or DLPs that are 1080 x 1920. I think you'll find they're either 720P, 768P or 788P and typically around 1300 horizontally.

Although you may find ONE LCoS TV that's 1080 x 1920 and very very expensive, I don't believe you'll find any others. Most of them are "720P" and not cheap.

Also, there are NO direct view TVs that do more than about 1400 lines (and that's the best from Sony). Most Direct View TVs do about 1000 lines at most. It has to do with the sizing of the shadow mask and limits associated with the production thereof and the tradeoff with brightness.

Also, you'll find that most fixed pixel displays don't have the "exact" 720 x 1280 pixels (although there are quite a few). Most LCDs (not all) are 768 or 788. So, in most instances, the signal is "converted".

I did not say they are chip, but they are coming (if not already out there). Anyway I would wait another year for either of them for the price to drop ( a little).

A few links.. All of these are 1920 x1080 (p)

I'm sure that by this time, next year the offer fill be double or triple from what is now, I suspect all brand names will offer at high end at least one model in this res.

 

[57]

There's nothing here that runs counter to what I said (Very very expensive, one of type displays). The links you supplied are mostly for equipment that runs US$10k+. I don't think many people will be buying these.

So, I'm a little confused. Is it an HD or ED display? Should I care? There is another LG plasma, same size, less $ (RU-42PX10), also described as EDTV.

Wondering also how these models stack up against Panny's TH42PA20? Thoughts?

Thanks.

I'm really confused by this set too. I saw it at a truckload sale, apparently LG had some sort of crazy promotion on it for 1 day only.

The price tag said '42px12x' in one spot and '42px12xc' in another.

Internet searching seems to indicate the 42px12xC is an older model, all silver bezel, 1200:1 contrast only. The LG Canada web site shows a '42px12x' that is HDTV (1024x768) and claims 5000:1 contrast ratio. I'd heard LG was going to be using a new 5000:1 panel in their higher end stuff so that's sensible.
One thing I noticed is there was no Farjouda logo on the set nor is it listed on the LG Canada site either.

It was even more confusing because the picture was better on an LG EDTV plasma beside it. The sales staff explained to me that was because their source was a 480-p DVD player that mates perfectly to EDTV resolution. They said when the HDTV panel upscales, it introduces video noise hence the worse picture. It seemed plausible enough, but later I stuck my head behind the rig and noticed they were only running a single weedy little composite line to the HDTV, which might explain the poor picture.

For some reason the LG was plentiful whereas the Panasonic EDTV for similar $ sold out fast. They told me the Panasonic was written up by Consumer Reports (not my most trustworthy source but I guess people really follow their rankings) Also they said the Panasonic was high contrast and was blowing people away.

I checked with Future Shop and they have nothing in their inventory except for 42px10. Are you sure you saw it at Future Shop?

 

[Neild]

It's a bit confusing that these are 1024x768 given that they are 16:9 aspect ratio glass. Mathemagically shouldn't they be 1366x768? I've seen several of these 1024x768 native res plasmas in recent days so maybe that's what the glass panel manufacturers are doing now.

 

[57]

Pixels don't need to be square. You'll also find 16:9 plasmas that are 1024 x 1024.

 

[Neild]

Ahh, good point. Only thing is I'm looking for basically effortless input from an HTPC. I have a lot to learn on the subject, but I think the computer PC video cards are assuming a square pixel. So the problem will be a stretched image if you send 1024x768 PC video into this panel won't it? I know there is all kinds of adapters and re-scaling, but my understanding is native resolution looks best.

OK found one of these 42px12x at Visions. Picture is absolutely stunning. Stunning!

I also did some looking around and found London Drugs had the PA20 and PX20 series screens. The PX20 looked better than the PA20, which makes sense based on the price premium. In a totally unscientific one-store-vs-another-store-across-town kind of test - the LG was every bit as good or perhaps nicer (?) than the Panasonic.

I looked at so many plasmas over the last week I can now tell at a glance which is a 480 line and which is a 768 line, even with a 480 line source.

Not wanting to go out on a limb here, but the LG is perhaps the nicest screen I've seen so far including the showroom $12k Pioneers.

Even so, faces in a dark surrounding show the limitations of the technology. Every brand I've seen so far exhibits the clown face effect under those conditions. It's hard to test for this though! I've had to bring my own discs in since the store's demo loops never seem to contain *any* material that exhibits this difficult to reproduce content.

Concerned, confused and a newbie

I have been researching the DU-42PX12X and am a couple weeks away from purchasing one. The last few posts seem promising but I am still a bit nervous about spending $3000+. I guess I am hoping someone might have some updated information/opinions on this unit.

Thanks Muchly

I had bithe the px10 nd px12....(at different times) I took them back and got the panny edtv pd50u...it had the best PQ of the three...I will say the LG did look great...the difference from the edtv to hdtv was very minor.....that might be my untrained eye.....but once I saw the edtv dispalyed as well as the LG hdtv it was a no brainer for me...I will add that money was a consideration......

 

[topazal]

I have LG 42PX11 at home. I don't have digital cable as I use analog. The quality is so-so viewing analog programming. However, with DVD, it's very nice.

 

[Damnit]

px 11 is that edtv or hdtv
