Specifies if the display is capable of colour or monochrome only.
	Foreground Color
Specifies the initial foreground color.
	Background Color
Specifies the initial background color.
	Bit Depth
	Color Bit Depth
Total color bit depth for the display.

	Physical Orientation
Rotates the simulated canvas to match the orientation of real world hardware.
	Scope Traces
Selects if the scope traces are automatically added to the data recorder window or not. Simulation - draws an approximation of the UART data onto the scope trace. ICT - sets up the scope trace for incoming data and adds UART packet decoding at the correct BAUD.
