any tvs out there that may have 1920 lines horizontal or 1024? I dont know of any and Im very new to this. Anyways If a Tv only shows 800 (approx.) horizontal and 1080 or 720 High, then in reality are we viewing things in "Hi Def"? Isnt true Hi Def a minimum of 921,600 pixels for 720p and for 1080i its 2,073,600 pixels? If the tv only has say 800 horizontal then the total pixels it shows say at 720 is 576,000 pixels while 1080i is at 864,000 pixels. Which is less than "True" Hi def. Is this correct? So In reality HD TV's are not showing True Hi Def video? Am I saying this right or should I have to relinquish my puff the magic dragon pipe?

I think this has been covered over and over and over...

well im slow so recover it! :confused:

I think he wants you to look it up yourself, as it will bore the rest of us to tears. "Search" function

oh, ok! However how do I look it up via search option without having 600 off topic posts come up? Anything specific to use as the keyword?

Here's a couple to get you started:

853x1080 = 921,240 = approx. 1 Megapixel = 3 times more detailed than SD = stop talking ABOUT THIS!!!

In my opinion, you are right.

853x1080 = 921,240 = approx. 1 Megapixel = 3 times more detailed than SD = stop talking ABOUT THIS!!!


853x1080 is still less than 1024x720 which is short of HD! Its not approx. I MP since it would be 1000x1000 which would equal 1,000,000 pixels. Im not saying its not better detail but its not "HD".

You got you math screwed up.
853x1080 = 921,240
1024x720 = 737,280

you probably meant 1280x720 = 921,600 > 921,240. Oh WOW, 300 pixel difference.... :rolleyes:




720 lines or more = HD.
1920x1080 = "Full HD"

Everyone is tired of arguing about this.

thanks for correcting me. I dont know why i multiplied 1280x720 when its 1024x720. I know this and yet I still kept multiplying it? Anyways thanks for the correction. With the new math there it does show that when its in 1080, the HD source IS TRUE HD. My mistake. And I really didnt want to squable for 300 or so pixels, my point was that if its not Equal to or more (in pixels) than its NOT True HD just a very close to HD. Although I wouldnt think anyone can tell the difference in just 300 pixels so to the naked untrained eye it may still look HD "Like". Although that makes it moot since true HD starts at 1024x720 so that makes 853x1080 True HD and not the obscure math I used for 1280x720. Oh and just to reiterate, I was mainly focused on you saying 921k is approx. 1,000k which even when you round it out, it sure is not. Now thats a difference of 80k pixels which would be a big difference compared to only 300 pixels. I still dont know how I ended up using 1280 instead of 1024. Thanks for catching that for me. I would have went on my whole life getting this wrong. It helps a lot now!

What are you talking about?

You did your math as 1024x720. The correct dimensions are 1280x720.
