I've searched and read various things on avsforum. Even one about my model Samsung (PN43E450) plasma. All the online specs say 720p. If I click info on the tv, say when halo 4 is playing through and older xbox360, the white xbox, it says 1280x720 / 60p. But everyone online says 1024x768 and the manual says 1024x768.

So do I have an hdtv or not? The picture looks great. I had and older sony 3 LCD Rear Projection. There is no comparison. Looks better than my son's LG lcd from last year, much better. Can see blacks and all detail in the blacks

I have seen others that say 720p isn't real hd anyway. I don't mean to argue that, just how I can have 1024x768 and it still be hd.

I know it looks good and all but like many of you....I just need to know the truth (and yes, I can handle the truth smile.gif ).

With respect, please don't tell me, If it looks good to you that's all that matters (okay, it's a big part, but I still want to know.)


Thanks for any help.

edit: when I put it on comcast F/X HD, and click info it says 1920x1080 / 60i. But I still have 1024x768. What gives?

Samsung 51" PN51E450A, Polk Tsi300, Polk CS 2 series ii center.

It's an hd set. It's not 1080p capable, but it's still hd at 720p and it's native resolution is indeed 1024x768 http://en.wikipedia.org/wiki/High-definition_television. It uses pulldown (think that's the right way to say it) to display 1080i but obviously doesn't have the capability to show 1080 lines at a time in any case.

This article was written a few years ago, but when it comes to 720p TV's, it still applies today:

Quote:
Ask HD Beat: What's the deal with 1366 x 768?
By Ben Drawbaugh
Reader Rob writes in and asks, "What's the deal with 1366x768? It seems like most of the HDTV's out there in the 32-37" range have those dimensions. How does that translate on a pixel to pixel basis, and why don't they do 1280x720?"

Rob that is a great question and one that has come up many times before. I even asked the Pioneer representative at CES this year the same question. His response was that it was a PC resolution that has been standardized. He was of course talking about XGA which is 1024x768 but it is the same premise. More pixels is better, there is no arguing that, but the question still remains where do the rest of those pixels come from and how can they make a 16x9 display from a 4x3 resolution? The answer is actually pretty simple; it is not a 1:1 pixel mapping and pixels don't have to be square. In fact the Pioneer Elite plasma (arguably the best plasma) has a 1024x768 resolution and rectangular pixels.
I know what you are thinking now; How can it look as good if they are scaling the 1280x720 or 1920x1080 video to a different resolution? (Well that is what you should be thinking.) The answer is surprising or it at least is surprised me. All TVs scale, yes all! The single biggest difference between a TV and a computer monitors is that TVs have overscan. The reason isn't a good one, but that is the way it has always been and that is the way it is now. That means that if you buy a TV with a native resolution of 1280x720 and the TV has ~3% overscan, the circuitry in the TV is throwing away 3% of your pixels and scaling the rest to fit into the 1280x720 pixels on the display. There are some TVs that have the ability to turn this off, they call it "computer" mode others call it a 1:1 pixel map. The problem with theis modes is that TV production folks expect you to have overscan, so they use the outside pixels for things such as Closed Captions or Neilson ratings, it is refered to in the industry as the vertical blanking interval. It also happens to be how those MovieBeam movies get beamed.

The bottom line is it really doesn't matter how many pixels your TV has as long as it looks good. If you are like me and your have an OCD for these type of things, buy a 1280x720 TV that you know has the ability to produce a 1:1 pixel map and ignore the garbage on the vertical blanking interval.

The resolution was lowered on the 51" E450 models this year, from 1366 x 768 to 1024 x 768. Not really sure if the pic quality has noticeably suffered. The 51D450 from last year had nice pic quality for 720p, but not sure if the 51E450 this year quite meets the same standard. But still considered HD, although perhaps HD lite.

Not a reply but an experiment that I tried. Would appreciate any critique on my methods. I have a PN43E450 purchased at BB. Worse than horrible in the store(s) Much better than expected at home. Yes it is wide screen - no doubt. I use an OPPO 103 as my source and OTA video. All the discussion about pixels and square pixels AND RECTANGULAR pixels just seemed too weird so I thought I'd see for myself.

Now to my very simple experiment. I decided to use my computer and make some rectangles in Adobe Photo Shop. The first was 1280 x 720, then 1024 x 768, then 1366 x 768, then 1368 x 768. All these were pixel by pixel. I put them on a USB stick and burned them into a DVD. Run them through the USB on the OPPO and the Samsung.

Guess what? The 1024 x 768 filled the top and bottom and left room on the sides. The 1280 x 720 sat in the middle of the screen black bars top and bottom. The 1368 (1366) x 768 filled the entire screen. I ran these images on my laptop monitor (1366 x 768) and the presentation was identical. On my 19" 4x3 desktop LCD 1600x1200 the results were the same. Filling the proper spacing on the monitor.

I next changed the resolution on USB stick to 1350 x 768, then 1340 x 768. The image shrunk on the right side of the screen.{ My screen shows some non uniformity on the left edge (NOTE All store display 720 Samsung seem to have this issue. Seems to be a manufacturing design. (columns of extra unlit pixels).} I can force to OPPO to do many different resolutions but the results were always the same. Please tell me my methology is wrong or I'm missing something here. ...

It seems to me that the panel is actually 1350+ x 768 pixels. No rectangular pixels here. It may be why the picture quality is so good for a 720P tv. Would really appreciate anyones thoughts on this.

These are definitely 1024x768.

The 51inch sizes used to have the higher pixel resolution, but now they are all supposedly 1024x768. But they all still have a nice picture.
