Intel Graphics Technology (GT) is the collective name for a series of integrated graphics processors (IGPs)
produced by Intel that are manufacture on the same package or die as the central processing unit (CPU).
It was first introduced in 2010 as Intel HD Graphics.
Intel Iris Graphics and Intel Iris Pro Graphics are the IGP series introduce in 2013 with some models of Haswell processors
as the high-performance versions of HD Graphics. Iris Pro Graphics was the first in the series to incorporate embedded DRAM.

Beginning with Sandy Bridge, the graphics processors include a form of digital copy protection and digital rights
management (DRM) called Intel Insider, which allows decryption of protected media within the processor.

Previously there was a similar technology called Protected Audio Video Path (PAVP).

Quick Sync was introduce with the Gen 6 in Sandy Bridge microprocessors on 9 January 2011.

In fact, Graphics Virtualization Technology announced 1 January 2014 and is supported by Iris Pro GPUs.
HD 2500 and HD 4000 GPUs in Ivy Bridge CPUs are advertise as supporting three active monitors,
but this only works if two of the monitors are configure identically, which covers many but not all three-monitor configurations.
The reason for this is that the chipsets only include two phase-locked loops (PLLs) for generating
also the pixel clocks timing the data being transferred to the displays.
Therefore, three simultaneously active monitors can only be achieve when at least two of them share the same pixel clock, such as:
Using two or three DisplayPort connections, as they require only a single-pixel clock for all connections.
Passive adapters from DisplayPort to some other connector do not count as a DisplayPort connection,
as they rely on the chipset being able to emit a non-DisplayPort signal through the DisplayPort connector.
As a matter of fact, active adapters that contain additional logic to convert the DisplayPort signal to some other format count as a DisplayPort connection.
Using two non-DisplayPort connections of the same connection type (for example, two HDMI connections)
and the same clock frequency (like when connected to two identical monitors at the same resolution),
so that a single unique pixel clock can be shared between both connections.
Another possible three-monitor solution uses the Embedded DisplayPort on a mobile CPU
(which does not use a chipset PLL at all) along with any two chipset outputs.
ASRock Z87- and H87-based motherboards support three displays simultaneously.
Asus H87-based motherboards are also advertise to support three independent monitors at once.
