Color temperature: A measure of color as related to the temperature of a very hot object. The cooler the object, the redder the light. The hotter it is, the bluer the light. Our sun’s daylight is 6500K, so this is the standard for monitors.
Hz: The refresh rate, as measured in hertz (Hz), is how many times a monitor changes image in a second. 100Hz+ feels best for gaming, but 60Hz is the max for current 4K monitors.
DisplayPort and HDMI: The two current PC and multimedia video connection standards. Both support audio and video and come in a variety of versions.
Windows scaling: To make most programs on your desktop readable on high-res displays, Windows has a setting that lets you ‘zoom in’. This makes things appear larger, and allows apps to bypass it, letting you view pictures, videos and games at full resolution.
