I have 2 MSI HD4850's. Both of them i cannot connect DVI cable. I have to use a DVI-VGA adaptor and connect it to analog. I have tried my monitor on a x1900 card and it works with DVI. Then i tried my card in that machine with my monitor and it doesn't display. But i can hear my pc beeps and even hear the windows sounds. I then connected the X1900 in my pc and it worked with DVI. Is there maybe a bios fix i can use? Like another manufacter bios?
