Fixed resolution
Fixed resolution refers to the number of pixels on the screen. Pixels refer to the smallest unit that makes up an image. The image of a TV is mainly produced by pixels () composed of many stacked points or lines, so pixels The amount is an important factor affecting the resolution. Resolution is one of the main evaluation criteria for TVs.
Response time
Response time is a specific indicator of TV. It refers to the speed at which each pixel responds to the input signal. Its unit is milliseconds (). The smaller the response time, the faster the pixels respond. If the response time is too long, serious tailing will occur when displaying dynamic images (even the mouse cursor). At present, the response time of TVs is usually between milliseconds, and a few brands such as Amoi's Jingshi series have reached the fastest response speed.
Contrast and Brightness
The greater the contrast, the clearer the white and black output, and the greater the brightness, the clearer the image can be displayed in a brighter environment. Under different operating environment lights, appropriately adjusting the contrast value will help the picture display to be clear.
Dual tuners
Built-in two digital tuners, you can watch two different channels of cable TV programs at the same time, with a variety of picture-in-picture functions. Without dual tuners, only the picture-in-picture function can be achieved, that is, one channel can receive TV signals, and the other channel can only receive signals from the signal source. It is simply impossible to watch two channels of TV programs at the same time.
