The monitor will come on display the windows logo wait for the desktop to come up then the screen will go black. If I turn power off and on the screen will come back on only for a second then go back off. It will do the same thing if I pull the video cable out and plug back in. It does not stay on long enough to get into the menu. I changed the resolution of the desktop several times no diff. I have also used this monitor on different computer's no change does the same thing. During this whole thing the power light will be green.

does it have warranty still, have you tried different cords and or plugs for example try the VGA output on it if you have the cord and if the still monitor supports it?
