is there different type of HD you can add on your tv

[#2]

I'm not certain I understand your question. What I think you are asking is whether there are different types of HD sources you can connect to your TV - and the answer to that question is yes.  These are the types of HD sources that people commonly connect to their TV:

• a cable or satellite TV HD receiver box
• a Blu-ray player
• an upconverting DVD player
• a PS3 or XBox game console
• the video output of a computer
• the video output of an HD camcorder

In addition there is 720p, 1080i, and 1080p... all considered HD.

720p, 1080i was the first generation of HD.  I believe it was most commonly referred to as HD ready.  1080p is what is considered as true HD.  Anything above a tv resolution of 480p can be considered HD.

An HD Ready TV means the TV can take a HD signal via cables and an HDTV has a built-in HD-capable tuner.

In other words- HD ready TV has no HD tuner and an HDTV does.

As for true full HD 1080P, Its really only full 1080P if your TV is at least 120Hz other wise there's no visual difference at 60Hz between 720P, 1080i and 1080P.

Are you sure about that?  I always thought the resolution played the biggest part in whether something is true 1080p as opposed to the refresh rate.

Eg.  A 36" TV that only has 1366x768 resolution will not play full 1080p but will "upscale."

A 23" TV that has 1920x1080 resolution can show full 1080p HD because it has all 1080 lines in the picture image.

I use a 23" computer monitor with 1920x1080 resolution at 60 Hz through HDMI at home, and I don't notice any difference on that than on my in-laws 50" plasma screen when I am playing video games or watching Blu-rays other than that the image is larger and the way the colours are displayed are a bit different.  The actual image quality isn't any better.

Who knows, I might be wrong, or not acclimated to "true HD" but there are plenty of TVs sold by FS that only have 60 Hz and are advertised as native 1080p TVs.  Are the descriptions false?

Just google 60hz Vs 120hz. I could try to explain it but would probably screw it up LOL.

Are the "FULL 1080P" stickers(those gold and black ones) on 60Hz TV's or are they just on the 120Hz and higher TV's? I think It's just on the 120Hz and higher TV's...maybe a fs ref can verify this.

I can't speak to the ones in store, but there are a number of 60 Hz TVs advertised on the website as Full 1080p HD.

Unless I'm actually proven otherwise, I'll maintain that "1080p" HD comes from the TV providing at least 1920x1080 native resolution, and not the refresh rate.  A 32" TV at 60 Hz that shows 1366x768 resolution (720p) will not show HD programming exactly the same as a 32" TV at 60 Hz that shows 1920x1080 resolution.

The higher the native resolution, the better quality image you will get when using the same refresh rate.

1080P is lines of resolution. 60Hz means the amount of times a TV can refresh per second. 60Hz= 60 frames per second, 120Hz= 120 frames per second. 1 frame= all 1080P lines once.

Cable TV HD channels are 30 frames per second @720P 60Hz, this gets you 30 frames per second x2, for a total of 60 frames per second or 60Hz.

blu-ray movies are 24 frames per second @1080P 120Hz, this gets you 24 frames per second x5, for a total of 120 frames per second or 120Hz.

blu-ray movies that are 24 frames per second @1080P 60Hz, well do the math 24fps doesn't go into 60 evenly. This is where 3:2 pulldown comes in to play.

3:2 pulldown, frame "A" is shown 3 times and frame "B" is shown 2 times, giving you the "3:2" pulldown. This means you get half the resolution or frames per second compared to 1080P 120Hz.
