I bought a used dx-4860. It has gtx-660 graphics card in it. The onboard hdmi port doesnt send a signal but the dvi on the graphics card does. Is this a setting in the bios? If I reformat will I get signal from the hdmi port untill I install the driver for graphics card? Im afraid if I reformat ill lose the dvi output with no driver and if its a setting in the bios the hdmi will remain dead and ill have no way to get in the bios. Does this make sense?
