CGDisplayMBS.SerialNumber as Integer

dim d as new CGDisplayMBS // pick main display

MsgBox str(D.SerialNumber)

Returns the serial number for the monitor associated with the specified display, or a constant to indicate an exception—see the discussion below.

This function uses I/O Kit to identify the monitor associated with the specified display.

If I/O Kit can identify the monitor:

If the manufacturer has encoded a serial number for the monitor, the number is returned.
If there is no encoded serial number, 0x00000000 is returned.

If I/O Kit cannot identify the monitor:

If a monitor is connected to the display, 0x00000000 is returned.
If no monitor is connected to the display hardware, a value of 0xFFFFFFFF is returned.

Note that a serial number is meaningful only in conjunction with a specific vendor and product or model.

CGDisplayMBS.UnitNumber as Integer

dim d as new CGDisplayMBS // pick main display

MsgBox str(D.UnitNumber)

A logical unit number for the specified display.

The logical unit number represents a particular node in the I/O Kit device tree associated with the display's frame buffer. For a particular hardware configuration, this value will not change when the attached monitor is changed.

The unit number will change if the I/O Kit device tree changes, as when hardware is reconfigured, drivers are replaced, or significant changes occur to I/O Kit, so it should not be assumed to be invariant across login sessions.

For more information about I/O Kit, see the Apple publication "I/O Kit Fundamentals".

CGDisplayMBS.UsesOpenGLAcceleration as boolean

dim d as new CGDisplayMBS // pick main display

MsgBox str(D.UsesOpenGLAcceleration)

Return value: If true, Quartz Extreme is used to render in the specified display; otherwise, false.

Quartz Extreme is an OpenGL-based, hardware-accelerated window compositor available in Mac OS X version 10.2 and later. Quartz Extreme requires a minimum hardware configuration to operate.

The information this function provides is typically used to adjust the demands of drawing operations to the capabilities of the display hardware. For example, an application running on an unaccelerated system could disable live window-resizing.

CGDisplayMBS.VendorNumber as Integer

dim d as new CGDisplayMBS // pick main display

MsgBox str(D.VendorNumber)
// 1552 seems to be Apple

A vendor number for the monitor associated with the specified display, or a constant to indicate an exception—see the discussion below.

This function uses I/O Kit to identify the monitor associated with the specified display.

There are three cases:

If I/O Kit can identify the monitor, the vendor ID is returned.
If I/O Kit cannot identify the monitor, kDisplayVendorIDUnknown is returned.
If there is no monitor associated with the display, 0xFFFFFFFF is returned.
