New 19" TFT Belinea Monitor with DVI-D and VGA connection. Graphics Card ASUS EN6600 SILENCER TD 256Mb with DVI-I output and VGA connection. New DVI cable connected with exact pins at both ends. Boots fine till reaching Windows Logo Splashscreen and then resorts to "No Signal--check cable" VGA cable will work to this monitor but with a Dark Green background which affects all letter displays especially in MWord. All colours are affected. Any help on solving the failing DVI connection welcome. Thank you.
