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.
