3
generation core processors are described.
All KTQ77 versions support analogue VGA and digital display ports (2x DP) via the Intel ® Q77 Chipset.
Optionally LVDS support.
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) can be activated at the same time and be used to
