Thread: Monitor does not start up with computer

I have trouble with a Dell monitor, and lights are not connected.

If I disconnect the monitor, I get a message that says: * Self test function, red, green, blue, white *. And off the network card to see if it conflicts with a card.

The operating system goes up but the monitor stays off with a light yellow instead of green. It seems that the monitor is not recognized ... but it is well connected.
Do I have to use a Windows installation CD...?

Hello.

Test the monitor on another PC or another monitor on your pc.

Hi.

Therefore do the same with the graphics card and good contacts, clear memories.
