The max resoolution that a 1080p tv can output?

Question

Apparently 720p tv's can output at 1080i. Does that mean that a 1080p tv can, in the future when they come out with higher HD resolutions, output at resolutions such as 1440i?

Answer 1

A 1080p TV has about 1920x1080 pixels.
In the future, if ever anyone wants to transmit at a higher resolution, the TV will definitely need a firmware upgrade , assuming the internal video processor is fast enough to process the higher bit rate.

However, such firmware upgrades are rare on TVs, so don't count on it.

Answer 2

No the <> resolutions won't be built into today's TV sets because they are not YET a standard....

1080P TV sets have a NATIVE Resolution of 1920 x 1080...
1920 dot's/squares per horizontal line and 1080 lines top to bottom....each dot is a pixel, and the TV will have just over 2 million pixels to create the details in the whole picture.

A 720P only has about 921,000 pixels to make the whole picture, so 1080P can break down a picture into smaller dots which reveal MORE DETAIL.

ALL HD TV SETS can recieve 1080 or 720 or 480 along with a bunch of different variants of these MAIN Picture
rates/ settings.

That's why NATIVE RESOLUTION of the display is so important....you want to know how many pixels are used to display the whole picture. Of course 1080P is the highest pixels, thus the Highest Detail you'll presently get.

Now it doesn't magically change a 480i signal into a 1080i signal....it's designed to display 480 signals in 480 lines of detail, and the detail is not improved much on low def signals.

Answer 3

No, 720p's cannot output at 1080i. They can accept 1080i signals, but HDTV's always display at their native resolution. Therefore, 720p TV's always display at 720p or 1280x720.

Since 1080p is the highest video resolution right now, 1080p is the highest resolution that a 1080p can accept. 1080p TVs will display at 1080p or 1920x1080.

While there are prototypes that display at 1440i/p, most TV broadcast companies don't even display at 1080i and none display at 1080p. We are not going to see 1440 sources for a long time.
