We have purchased a DG45FC motherboard and wnat to use existing monitors. We have determined the HDMI video port is working correctly, but we need to get the DVI-I video port to function to use older monitors. We have tested the DVI-I port and can't get it the function. We used an older monitor with a 15 pin to DVI-I adapter attached to the port, but there is no responce. How do we configurate the motherboard to use the DVI-I port?
