What is Full HD 1080P?
High definition has been widely used in the video field, such as set-top boxes, cameras, TVs, projectors, etc. We often hear the term full HD in applications, so what is full HD?
Full HD is the English name for the screen resolution of flat-panel TVs. Generally speaking, when the physical resolution of the screen reaches 1920×1080, we consider this TV to be a full HD TV. Full HD refers to the inherent physical properties of the screen, which will not change due to changes in the signal picture. Regardless of whether it is cable TV, DVDs or high-definition videos on PCs, full HD TVs always maintain a physical resolution of 1920×1080.
1080P, which we often talk about, is a high-definition signal format. P stands for progressive scan, which means that each signal picture is scanned vertically to display a resolution of 1080 lines. When a model is marked as supporting 1080p signals, it means that the internal circuit can process 1080p input signals. At this time, no matter what kind of screen is used, even if its physical resolution is only 1366×768, or the screen ratio is 4:3, or even just a black and white screen, it can be said that the model supports the 1080p signal format, but its display image is not the original 1080p image, but is output after a certain conversion.
Currently, many digital devices can support 1080P. The so-called full HD 1080P TV is a TV that truly realizes the point-to-point display of 1080p images. It must meet two conditions at the same time: one is that the physical resolution of the screen is 1920×1080 in accordance with the Full HD standard; the other is that the internal circuit of the TV can process and output the picture signal in 1080p format.
In response to the current demand for full HD video capture, Purplelec has launched DVI capture cards, HDMI capture cards, VGA capture cards, SDI capture cards, color difference component capture cards, etc., which can support full HD 1080P capture, and can automatically identify and adapt to unconventional resolutions, such as 1366×768, 1440×900 and other resolutions.
