I received the super fancy new 24" display today, but the color is terrible and it is stretched in the width. When I try to use the 1200x1920 setting the display blacks out and then returns to 1200x1600. I read that the single-linked cable should work and there is a similar one included in the box. The same problem occurs with the two different installs (32 and 64 bits). The video card should be OK, but maybe it is faltering?
