OLED monitors do not require a backlight, which allows for individual pixels to be turned off, creating deeper blacks and better contrast.
HDMI is a common port for transmitting high-definition video and audio from a device to a monitor.
IPS monitors offer better color reproduction and wider viewing angles compared to TN monitors.
Resolution is the number of horizontal and vertical pixels displayed on a screen, such as 1920x1080 (Full HD).
The refresh rate is measured in Hertz (Hz) and indicates how many times per second the image on the screen is updated.
