Hi's to all.. am here in hopes I can get an idea for what might be happening. The monitor currently in use here working fine with a DELL pc.. Am puzzled over what is happening. With an atttempt to s simply connect this monitor to another pc it is not responding.. works with one but not the other??? Scratch my head.... the pc it is not working with has no OES. have win 7 to install in it.. The cable has a tight connection fit on both pc's.. Just got this pc back from a tech who had it hooked up to his monitor.. what could I look at to troubleshoot
