The AR-B1476 supports CRT color monitors. AR-B1476 used onboard VGA chipset and supported 1MB on-board
VRAM. For different VGA display modes, your monitor must possess certain characteristics to display the mode
you want.
To connect to a CRT monitor, an adapter cable has to be connected to the DB1 connector. DB1 is used to
connect with a VGA monitor when you are using the on-board VGA controller as a display adapter. Pin assignments
for the DB1 connector are as follows:
