Help! Have Toshiba Laptop, and HannsG 2nd monitor. Tried several times to get bootup to begin with laptop. (i.e., both are off, begin with computer then monitor to hook up, etc.) However, it seems only to to bootup on the HannsG monitor, and leaves the laptop (though on) black. Cannot move items between the 2 monitors as in past. It has worked in correct order in the past, before I had to move office from downstairs to upstairs. Any ideas?
