Graphic card connectors

Installing 2 new Dells ( a Core i7 and E8400) both with ATI HD 3650 cards. The cards come with 3 connectors a DVI, a DisplayPort (unexpected) and a HDMI. A few points

• Only two of the three connectors can be used at any one time (any of the two),hence the card can drive only two monitors at once. Plug three in and ATI catylst centre knows about then an gives the option of dragging the unused one to replace an existing one.
• DisplayPort adaptors are available - but the best ones are with a short lead (about 15cm) otherwsie the connector is quite long and heave on the card.
• When using a DVI to VGA connectors it does not use all the DVI pins. This I discovered after much struggling when one machine would not display anything from the DVI with a DVI monitor but when a VGA monitor was plugged in and a DVI>>VGA adaptor was used it dispalyed OK. THre was a cracked sinlge port on the DVI output and the DVI connector enaged this but the DVI>>VGA adaptor did not use this pin socket!
