What is dielectric constant?

The dielectric constant is a dimensionless physical quantity that measures the degree of polarization of a dielectric and is defined as the ratio of the vacuum capacitance to the capacitance in the presence of the dielectric. The larger the dielectric constant, the stronger the polarization ability of the dielectric, which can enhance the capacitance and weaken the electric field strength. It is critical in electrical engineering and electronics, affecting the performance of capacitors, insulators and electromagnetic devices.

The role of vga interface

The VGA interface (Video Graphics Array) is an analog video interface that connects the computer graphics card and the monitor to transmit video signals, including RGB color signals and synchronization signals. The VGA interface has high compatibility and is easy to use, but its transmission of analog signals will cause a decrease in image quality, and the highest resolution only supports 1920×1200, and the cable volume is also large.
