Intel motherboard DQ77KB was a Thin Mini-ITX form factor board, there was not enough space to add different video ports; so Intel decided to install an eDP. Intel stopped producing desktop motherboards since 2013.
The board is old now, for further assistance I suggest you our website: http://www.intel.com/content/www/us/en/support/boards-and-kits/desktop-boards/intel-desktop-boards-with-intel-q77-express-chipset/intel-desktop-board-dq77kb.html?wapkw=intel+desktop+board+dq77kb
