Monitor worked fine since original purchase date. Added new video card approximately six months ago. Worked fine until this morning. Turned on/off. Checked all connections. Unable to access OSD to attempt factory reset. Changed cable to HDMI with same results (scrambled screen). Connected old monitor and it displays normally. Any suggestions? PICTURE OF SCREEN ATTACHED
