I believe then you have ENOUGH space on TWO external display for editing your qranger styles/songs..
This are the display resolution for each VGA and DVI port:
640x480
800X480
800X600
1024X768
1280X800
1280X1024
1366x768
1440X900
1680X1050
1920X1080
1600x1200

The automatic xorg.conf script will reconize automatically the displays connected.
Note: On K10N78 is still free the PCIexpress slot, IF you install there one Nvidia PCIe card, you can have another 2 displays out ( 4 total + the MS display)
( no more PCIe available on mainboard..pity.. )

from october, wil be also available on web store 6 new external touch screen display: 8.4", 10", 15", 17", 19", 22" at really LOW price!
