Tightvnc Mirror Driver Windows 10
I have two mirror drivers showing up in Device Manager (in Windows), from RealVNC and UltraVNC. What exactly does a mirror/hook display driver (adapter?) do?
I'm curious about the actual mechanism(s) of functionality, and why a regular display driver/adapter doesn't suffice.

Based on this description, it's simply a virtual driver that mirrors the operation of a physical device. It's basically installed as a driver for a virtual graphicscard. This means it gets immediate notification of all display updates,allowing the VNC server to react quicker and use less CPU. A regular display adapter doesn't suffice because you aren't interacting with hardware (a monitor) the same was as if it were plugged in normally.

A mirror driver is a display driver for a virtual device that mirrors the drawing operations of one or more additional physical display devices.

When video mirroring is active, each time the system draws to the primary video device at a location inside the mirrored area, a copy of the draw operation is executed on the mirrored video device in real-time.[1]
Windows' mirror drivers were first introduced in 1998 with the Windows 2000 display driver model, which was renamed later to XPDM. In 2006, for Windows Vista, Microsoft introduced a new Windows Display Driver Model. The older drivers were still supported under Vista, but since the older model did not encompass support for features first introduced with Vista, those newer features would necessarily be disabled when an older driver was active. As a consequence, when a mirror driver designed for the older model was active, such as when Windows Remote Assistance or Windows Live Mesh were in use, Vista disabled Desktop Window Manager and Windows Aero.[2] Free online fashion runway solitaire. A similar situation existed with the transition from Windows 7 to Windows 8. Beginning with the DDK targeted at Windows 8, mirror drivers have to fulfill very exacting specifications - they must support a specific set of functions, and no more than those.
Windows installations come with two mirror drivers preinstalled - 'mnmdd' used by NetMeeting, and 'RDPDD Chained DD' used for Terminal Server/RemoteDesktop services. Third-party mirror drivers are included with screen readers such as JAWS, Window-Eyes and FreedomBox; the monitoring software LanSchool; and remote desktop software such as Timbuktu, LogMeIn, UltraVNC, TightVNC, Radmin and RemotePC.
