Everything about Full HD(1080p) TVs

Full HD(1080p) is 1,080 pixels (or pixel lines) sequentially displayed on a TV screen. In other words, scanning and slowly showing all lines or pixel columns. It reflects 1,920 pixels across the screen and 1,080 pixels running from top to bottom with sequential display of each line or pixel column. You subtract 1,920x 1,080 to get the maximum number of pixels shown on the entire screen area, which is equivalent to 2,073,600 or about 2.1 megapixels. This article will cover everything about Full HD(1080p) TVs.

Category of Full HD(1080p)

When video pictures can be shown following the rules above, a TV can be marked as a Full HD(1080p) TV. Plasma, LCD, OLED, and DLP are the types of TV technologies that support the development of 1080p images for the TV.

For a Full HD(1080p) Screen, it must change the incoming signal from 1080p to a lower resolution video signal, such as 480p, 720p or 1080p. In other words, an electronically variable display of 1080p on a TV may be obtained or the 1080p signal may be transmitted.

Full HD(1080p)/60 vs Full HD(1080p)/24

Almost all HDTVs that directly accept a 1080p input signal can accept the so-called Full HD/60. A signal of Full HD/60 transmitted at 60 frames per second (30 frame, with a frame shown 2 times per second), is shown at a resolution of Full HD/60. This is a regular 1920×1080 pixel video signal progressive scan.

Nevertheless, a “new” 1080p version was introduced with the introduction of the Blu-ray disc: Full HD/24. In its Native 24 frames a second (for example, the movie on a blu-ray disc), Full HD/24 reflects the frame rate of the regular 35 mm video transmitted directly from a source. The idea is to make the picture look more normal.

It ensures HDTV must have the ability to accept an image of Full HD/24 resolution at 24 frames per second in order to display a Full HD/24 photo on an HDTV. All the Blu-ray Disc players can also be programmed to emit 720p, 1080p, and Full HD/24 signals to TVs that have no such functionality and, in most situations, the Blu-ray Disc player automatically senses the right frame / resolution level.

The HD Ready TV Dilemma (not Full HD)

Another thing that consumers need to realize is TVs with an input signal of 1080p but a native resolution of 1920×1080 is actually lower. In other words, when you buy a TV with native pixel resolution of either 1024×768 or 1366×768 (that is marketed as HD Ready TVs) it only means that those TVs can view the number of pixels horizontally and vertically on the monitor. In order to display the signal as image on the screen, a TV with a native 1024×768 or 1366×768 pixels resolution actually needs to downsize a 1080p incoming signal.

It should be remembered that some older HD Ready TVs do not receive 1080p output, but allow video signals up to 1080p. The number of pixels received is the same, but are outputs in an interlaced format (in an odd / even series per row of pixels is sent alternatively) and not in progressive format (in a linear manner, every line of pixels is sent). In this situation, a HD Ready TV must not only “deinterlace” or turn the picture interlaced into a progressive photograph to show a photo on the screen.

All of this ensures that you will see a resolution image on the monitor when you buy a TV with either 1024×768 and 1366×768 pixel resolution. A 1920x1080p picture is therefore reduced to 720p or a 480p image down to 720p. How good the video processing circuit is on TV depends on the results.

The fourth factor(4K = 4 times Full HD)

The choice of 4K quality video channels should also be taken into account. It should be pointed out that most 1080p TVs can not accept input signals in 4K resolution. In other terms, we can’t accept a 4K resolution video signal, as opposed to 480p, 720p, or 1080p signals that can be scale up by a 1080p TV or modified to display it additionally.


Although TVs with various native display resolutions are available, do not allow this to confuse you as a consumer. Keep in mind your TV area, the types of video sources you have, your budget, and how you view the images.

Once considering buying a HDTV less than 40-inch, there is a tiny, if visible, graphical disparity between the three main high-definition options 1080p, 1080i and 720p.

The wider the display, the more the gap between 1080p and other resolution is apparent. It’s safer to use 1080p when you consider buying an HDTV of 40-inch and greater screen size. In fact, concern for the 4K Ultra HD TVs in a 50-inch or greater screen size can be useful (though the 40-inch screen size excludes 4K Ultra HD TVs).
