I have a Syncmaster 920Nx. I am using an Nvidia 7x series graphics card. I have two monitors hooked up, an old Dell Monitor and this one. Both ports of the graphics card works with my dell monitor but I can't get the Syncmaster to display anything anymore. The power turns on but the screen stays blank and OCCASIONALLY will blink slightly. The power light blinks on the monitor as well. I have no idea how to fix this and was hoping you could help me. Thanks.
