My 1410 has some issues with the display out function. It moves well with both the HDMI and VGA output when the lid is open. However, when I close down the lid, the display seems fine for few seconds and then after it got flashed up on and off continuously onto the display which I have connected this up to. It happens with both the VGA and HDMI output signal. It only moves on when the lid is closed, even though I configured the system to do nothing when the lid is closed.
