HDMI interface
HDMI (High Definition Multimedia Interface) interface is a high-definition multimedia interface that can transmit audio and video signals at the same time. HDMI interface is widely used in TVs, computers, game consoles and other devices. It supports high resolution and high refresh rate and can provide excellent audio-visual experience.

USB-C interface
USB-C interface is a multi-function interface that can not only be used for data transmission and charging, but also for connecting to monitors. Some high-end laptops and monitors use USB-C interface for video output, which has the advantages of convenience and fast transmission speed.
In short, there are many sizes and interfaces of LCD screens at present, and users should choose according to their needs and device compatibility. Whether it is a small mobile phone screen or a large LCD TV, whether it is a traditional VGA interface or an advanced USB-C interface, they all have their own characteristics and applicable scenarios. With the continuous advancement of technology, I believe that the size and interface of LCD screens will continue to develop and innovate in the future, bringing us a better visual experience.
