Ward,
I understand where you are coming from saying that anything under 42 inches isn't HD. I might not agree with you, but i understand what you are trying to say.
But to say that anything under 50 inches is EDTV is going way too far and incorrect.
"So what is it then?" you might say. If it's not HD, I don't know what it is, but it's definetely NOT EDTV.

I think his only assertion is that any PLASMA under 50" is not HD because the horizontal resolution of those sets is only 1024 instead of 1280. When watching HD content with a 42" Plasma set, some of the signal is being "tossed out" and cannot be displayed simply because the signal contains more resolution than the TV is capable of displaying. I too acknowledge that he is correct that the full 720P signal cannot be displayed and that some resolution is lost, but I cannot find any publication that establishes the full 720P ATSC DTV standard as the minimum resolution to qualify for HD status.

As to your resolution point, there currently is no industry defined resolution between HDTV and EDTV. If something is not HDTV then must be EDTV unless the manufacturer wants to "invent" a new marketing term that is not controlled by standards bodies.

I don't agree that if it's not HD that it MUST be EDTV. If edtv is the same as ANY 42 inch tv that CLAIMS to be hdtv, then why do we see ANYBODY marketing there 42 inch tv as edtv if they can just market it like all the 42 inch sets that don't say edtv on it?
Think about it, it makes zero sense.

Here a a 1024x768 LG saying it's HD
they lie to....LOL

PureVision PDP-4340HD 43'' Plasma TV (16:9, 1024x768, HDTV)

These sets also have 48 more vertical lines of 1024 than regular 720p sets.

END OF STORY

(4) The manufacturer quality should be of more concern than the resolution of the plasma display. Purchasing a plasma from a quality manufacturer can make the biggest difference of all. I would rather have an EDTV 853X480 plasma TV from Sony, Panasonic or Pioneer than an 1024X768 HDTV plasma from lesser Taiwanese, or Korean manufacturers even for the same cost.

Now to end this debate it is in the Vertical

It's All In the (Vertical) Resolution.
"Think of resolution as picture detail. Standard-definition (SD) TV -- the sort most of us have been watching for years -- has 480 visible lines of detail, whereas HDTV has 1,080i visible lines of detail. This is the number of horizontal lines found on your TV screen. Remember, TVs are measured on the diagonal: The width of the screen changes, while its height remains more or less constant. Thus, it is the number of pixels on the vertical axis that really determines how much detail is visible."

All kidding aside If he don't admit he was wrong no one will ever respect his posts.

Just located independant article;

"Note: This article addresses the issue of ED ("enhanced definition") and HD ("high definition") as it pertains to the native resolutions of plasma displays. Plasma TVs are unique among fixed-pixel displays (e.g., LCD and DLP) in that similar-sized plasma displays from the same manufacturer can have entirely different native resolutions. A 42-inch flat-panel plasma display, for example, comes in at least two resolution "sizes": 854 x 480 (called ED) and 1024 x 768 (called HD). Not surprisingly, the reason is cost: It simply costs more to produce higher resolution plasma display screens due to the number of pixels included in the panel."

Posted by me in a previous post in this thread;

"HDTV has a total of 1,125 scan lines, but it only uses 1,080 of these
for the actual image (hence the "1080i" HDTV specification). There are
1,920 pixels in each interlaced scan line, so our HDTV pixel
calculation looks like this:

1,080 scan lines x 1,920 pixels/line = 2,073,600 pixels"

I find the equation above compared to the statement above that to be in conflick with each other.

What does this show us?
It shows us that in this day and age with technology changing so rapidly combined with the amount of information both good and bad that one can find documentaion to support a given position on this topic as well as most any others you would wish to argue.
What does not change is that beauty is in the eye of the beholder and is the reason why so many different types of Tv's are and stay on the market, different strokes for different folks, myself included.

"Half empty or half full?
You can see why 768x1024 is rated HDTV.
I would have never bought this set if I felt Panny was misleading or the set was not HDTV."

The above statement in the first post of this thread seems to be a self justification in the persons purchase and the enitre post arguemenitive in nature. If this is what you know for fact dude congratulations, enjoy your Tv.

In re-reading this part of the post i would ask this question;

Not being familar with Panasonic or thier line if 768x1024 is considered HiDef( i disagree that it is), do they make Tv's/Monitors with higher resolutions and if yes...why if 768x1024 is HiDef?

If 1366 x 768 is HD, then what is 1920x1080?

1366X768 is the minimum resolution to be considered HD and it also has a 16X9 aspect ratio.

1920X1080 is a true 16X9 aspect ratio. It also exceeds the minimum requirements to be called HD which is at least twice the resolution of SD.

As explained in my prior post 1024X768 is a 4X3 aspect ratio and does not meet the requirements to be true HD.

weberman · 02-20-2006, 04:33 PM

I posted this but it did not take so this repost is the one I refer to in my post above.

To repeat:

A 1024x768 resolution has a 4x3 aspect ratio (The math is 1024 divided by 4 times 3 equals 768 or if you prefer 768 divided by 3 times 4 equals 1024) and therefore cannot be HD because HD has to have a 16x9 aspect ratio. The 1024X768 display has rectangular shaped pixels that allows the 4x3 1024x768 resolution to be scaled to cover the 16x9 display area required for HD.

Any time you have a fixed pixel display, and it's being fed some other resolution than its native resolution, there will be scaling issues. How noticeable they are or how annoying they are dependes on how good a job the display does in handling the problem and/or how sensitive you are to the issue.

1024X768 cannot be native HD because it is a 4X3 aspect ratio. It must be scaled and has been, I believe, falsely promoted as true HD.

I am not commenting on any brand or type of TV based on a subjective opinion. If you don't believe this just do the math concerning the requirements for HDTV.
