1. Resolution
The resolution of LCD TVs is fixed, unlike computer LCD monitors, which can adjust the resolution. The fixed resolution of LCD TV is also its optimal resolution, and high resolution can be easily compatible with HDTV. For any video signal that is not the optimal resolution for the LCD screen, the LCD TV needs to convert the image resolution before display conversion.
2. Response time
The so-called "response time" refers to the reaction speed of the LCD screen to the input signal, that is, the reaction time for the liquid crystal to change from dark to bright or from bright to dark. Obviously, the smaller the "signal response time" indicator, the better. The smaller the response time, the user will not have a feeling similar to afterimages or dragging when watching moving pictures.
3. Interface
When purchasing, don't just look at the surface, but also look at the interfaces on the back of the TV. These interfaces directly affect your "investment protection", so they are very important. For LCD TVs, the best interface standard is HDMI, which is a digital interface that can transmit audio and video signals at the same time. It not only simplifies connections and reduces the wiring burden, but also provides the huge bandwidth required for digital signal transmission.
4. Bad screen pixels
The problem of dead pixels is one of the biggest problems plaguing LCD TVs. Dead pixels on the LCD panel cannot be repaired, and the LCD panel can only be replaced, and the LCD panel accounts for at least 70% of the cost of the entire LCD TV.
