OTEE: When the selected monitor resolution is not a native panel resolution, the text contents appearance in the monitor
screen is expanded in a horizontal or vertical direction to show the non-native resolution to full screen. This expansion is
done by interpolated resolution technologies, which are normal and widely used in flat panel devices.
The maximum or recommended resolution may be set to 3840x2160 depending on the connected computer’s video card.
