2.5 KTQM77 Graphics Subsystem
The KTQM77 equipped with Intel ® i3, i5 or i7 processor, supports Intel ® HD Graphics 4000.
All KTQM77 versions support eDP (Embedded DisplayPort) directly from processor, and analogue VGA
and digital display ports (DVI, 2x DP, LVDS) via the Mobile Intel ® QM77 Chipset. The Analogue VGA
and DVI-D are sharing the DVI-I connector.
The DP interface supports the DisplayPort 1.2 specification. The PCH supports High-bandwidth Digital
Content Protection for high definition content playback over digital interfaces. The PCH also integrates
audio codecs for audio support over DP interfaces.
Up to three displays (any three display outputs: DP0, DP1, DVI-D or DVI-A, LVDS or eDP ) can be
activated at the same time and be used to implement independent or cloned display configuration. PCIe
and PCI graphics cards can be used to replace on-board graphics or in combination with on-board
graphics.

2.5.2 Graphics Adapters
Use of DP Adapter Converters can implement HDMI support or second VGA or DVI panel support.
The HDMI interface supports the HDMI 1.4a specification
including audio codec. However limitations to the resolution
apply: 2048x1536 (VGA), 1920x1200 (HDMI and DVI)
1051-7619 Cable DP Extender cable 200mm DP to VGA DP to HDMI DP to DVI-D
(when using two DP converters) PN 1045-5779 PN 1045-5781 PN 1045-5780
Notice that only the DP to VGA adapter is an “active” converter the HDMI and DVI converters are
passive and cannot be used in a triple panel configuration.
