I\’m using it with an old Acer monitor. The Acer is connected through a VGA connection and Samsung is through an HDMI port. Everything was working fine until I rebooted the system. I just reformatted the system a few weeks ago.The splash screen came up, with sound, and then blank screen. Unplugged the HDMI and it works ok on Acer monitor. Any suggestion?
1) What happens if you boot up with just the Acer, then plug in the Samsung once in Windows?2) Have you got Windows configured to clone the monitors or extend the desktop across 2 monitors?3) Try setting the Samsung as the primary monitor.4) When you say splash screen, do you mean the Win 7, or a POST splash on the computer?
