When I try to connect Sony VPL-DX 100 projector with desktop HP 110-215in via VGA male to female data cable ( having one male and two female type connector ), the image on projector screen is not full and some portion is missing. The image on monitor is o.k.. However, when I connect projector directly to the desktop ( without monitor ) without VGA male to female data cable, the image on projector screen is o.k. There is one VGA slot and one DVI-D slot on the desktop. I tried to change screen resolution, but it didn't work. I want the display of monitor and projector screen to be of the same dimensions and no cuts. Any solution please...??
