What is the Difference Between 720p and 1080p HDTVs?

This is simple. They are both High Definition, but 720p has 720 pixels vertically whereas 1080p has 1080 pixels vertically. Think of you having a 20" TV. If you have 1080 pixels in that 20" TV, you will have a higher quality than having 720 pixels. Understand? But to sum it up, 1080p is a higher quality. :)

Having played PS3 on a 1080p 22" TV, and a 720p 26" TV, I can tell you that my 22" TV proved a lot better, sharper and clearer graphics. I can actually see my way around GTA IV! (On the 26" TV, it's amazingly dark in certain games).

I'm not sure that there's a HUGE difference, but IMO it's noticeable.

The difference is slightly better quality picture when using HD, it wont be a huge difference unless your using an expensive cable/lead to show films etc.

There is a difference, 1080 has 2 times the number of pixels as 720. It will be noticeable if you have a large enough display and sit close enough. At a certain distance you won't be able to tell the difference. Link

depending on what you use it for.

For gaming it will make all the difference. Watching regular TV there is no difference. If you in intend to ever connect it to a computer or use HD material you probably should go for 1080P.

Too summarize for high-quality content 1080P for "normal" use 720P.

Depends directly on the content, If the content is 720p then the quality is alot less compared to that of 1080p.

Basically 1080p holds more information but only if the content has it. Having a 1080p hdtv is useless if you don't have 1080p content on it.

There are more pixels on the screen with 1080p. That means smaller screens will look really good with 1080p but things might be really small. That also means the screen can be larger on a 1080p HDTV and it will look less square.

But most of the time things like TV won't be actual full 1080p. Only things like movies and some games will support full 1080p.

A 720P 'HDTV' has a maximum (or recommended) resolution of 1280x720 pixels while a 1080p screen guarantees 1920x1080 pixels. That's the very basics, not taking into account MHZ or response time. Today you want a 1080p TV to be able to play Blue-ray content fully while most TV casts are aired in 720p. I would also recommend a 1080p if you intend to use the screen with your computer or gaming console.

You will definitely notice a difference if the content you are playing supports full HD (1080p) vs 720p.

For best possible connection use a picture/audio source with a digital out such as HDMI, Display Port or DVI.

The difference is the resolution. 1080p is the best, I would go for that if you have the money.
