I have a Asus P8H61-M LE motherboard with Intel HD Graphics 2500 and I'm using my VGA port to connect a monitor. Few days ago I've bought an DVI to VGA adapter so I can use my DVI port to connect a second monitor that have a VGA connaction, but it doesn't work, the computer doesn't show that have been any connaction, and theres nothing on the second screen.
What to do?
You have one monitor connected via VGA to the VGA port on your motherboard, and another monitor connected via VGA-to-DVI into the DVI port on the motherboard - is that correct?
The motherboard (according to this link; ASUS - P8H61-M LE) has a DVI-D input connection. This means that it only accepts a digital display connection, so using an adapter on a VGA (VGA = analog) will not work. You need to get a DVI-D cable to connect between your display and motherboard for it to activate.
Let me know if you have any other questions,
