Just got my LG E2240T monitor. Hooked the DVI-D cable output to the HDMI output on my GTX460. Turn machine on, all I get is "Check signal cable". They are not handshaking
But if I think connect the VGA > VGA, monitor shakes with machine. I can then plug in the DVI-D, select that as the input, then remove the VGA. But if the machine sleeps, it loses the connection and wont handshake again?
