Resolution/image Size LCD and Refresh Rate

Resolution of the LCD display has a fixed size, it means the data displayed will always be of the same magnitude. For example, when the RGB panels with the size of the matrix 1366x768 means there are 1366x768 = 1,049,088 RGB dots. When the transistor-based, meaning there are a number of active transistors it on the displays. When FET based active fet means there are a number of that displays/panel.

With the number of 1,049,088 pixels, means any period of appearance of the image, the screen will load/display digital data of RGB bits 1,049,088 (in one period). Because of the size of the screen fixed and fixed data size, data size screen coordinates are stored in the firmware, when it is changed or does not match, then the image will be shown smaller or camp (because of the size of the image data is larger than the screen size).

Technically, the LCD TV in the process image data captured by the antenna/other source, its size will be diresize (adjusted) first match screen size before the data is sent on the screen. If the original image is smaller than the screen size then in-zoom, when larger then scaled down. Pemrosesnya blocks known as scaler. Scaler and CPU need RAM for this process.

Refresh rate is the number of times the screen is cleared and drawn again in a second. This speed depends on the quality of the screen and the quality of the image that will be displayed. The faster refresh rate, the more does not Flash. But the more extravagant resources. In the system PAL, wearing a 50 Hz refresh rate, which means that every second image deleted and drawn as much as 25 times.

The photo above is the type of damage caused unsuitable between the data panel the panel data set in the firmware with the size or specification of the panel. The picture looks cut off and not exactly one full screen.
