YATVT: Why are "720p" LCDs 1366x768?

[mercanucaribe]

Why not the native 720p resolution, 1280x720?? Being 1366x768 means that every pixel in the image has to be interpolated to fit the screen. So what is the manufacturers' reason? Is it somehow cheaper to build a higher resolution panel?

 

[LS20]

i dont know, bug it bugs me. 1024x768 plasma panel here =[

 

[keeleysam]

Marketing.

 

[QED]

I think a better question is.. why did 720p become a standard HD resolution instead of 768p when you consider that 768 lines of resolution has been a staple in direct-view panels for years?

They are marketed as "720p".

 

[jtvang125]

Just one more reason to go 1080p instead.

Maybe they just don't use the extra pixels. 1280x720 fits inside 1366x768.

Perhaps it's so they can show 1024x768 1:1.

So a 1920x1080 TV is going to throw away a bunch of pixels, and interpolate the rest? I think the author of that article is confusing HDTV with analog....

The single biggest difference between a TV and a computer monitors is that TVs have overscan.

and here i was thinking that TVs have a tuner and that is the biggest difference

There is a "safe area" that all cameras have.

Talk to video guys covering an event. They shoot a lot more than what you see. I always love to talk to them so that I can understand a little better.

That's the entire concept of overscan....delivering/framing.

 

[EKKC]

worse i've seen are 1024x1024 panesl. rectangular pixels FTL. actually FTFL!!!

What does the one have to do with the other? They don't have to broadcast the full frame that is filmed/taped.

So you are going to fundamentally change how crews are trained and have them push to the edge of the frame?

Good luck with that.

We will always have overscan.

You completely misunderstood me.

Not really. They broadcast the "safe" area due to the assumption that overscan is used.

What's first? Chicken or egg?

See now you understand what I'm saying - it has nothing to do with the way it is filmed, the extra information could just as easily be chopped off before it is broadcast and HDTVs would display everything they get. It is the way it is because of backward compatibility.

And like I said....good luck changing a well established system/industry based on a few pixels.

You still aren't on board with HD so I understand your pessismism. The year is 2007. Get with the times.

for a single reason:

1080p = 1920*1080 = 2,073,600

720p = 1280*768 = 983,040

1080p is over two megapixels. 720p was just under 1. so they added 86 horizontal lines to makeup for it.

1366*768 = 1049088

I've NEVER seen a TV advertised as "1 megapixel". Have you guys who are saying it's for advertising??
