I usually use two monitors and my graphics card (AMD Radeon HD 5450) have 3 inputs: HDMI, VGA and DVI. Whenever I use the vga and a dvi to vga both monitors will work. But if I use a dvi cable for the dvi output on the gpu instead of the dvi to vga and use a vga cable into that, only the dvi monitor will be detected. Any clue how to fix this? Thanks in advance.
