I have a XFX 290x 4gb and i always use it with my monitor benq on DVI-1 and a TV in the hdmi. Since last weekend the HDMI was not showing the tv, i change the cables and it wont work anyway.
Today i remove the card and reinstall all the drivers and did some test. So i discover that the DVI-2 was no work either, just like the HDMI. It won't even show the bios signal.
What could happened?
