I have an i5-based DG67BL intel motherboard computer that has a DVI and HDMI ports with one DVI monitor connected to the DVI port.
I added an GeFORCE 210 graphics card to it that has a VGA and a DVI ports and connected additional two monitors to it.
So far computer is working fine with three monitors configured in windows as extended desktop.
This motherboard has just one PCIeX16 slot. It has 2 PCIeX1 and a PCI slot that are vacant.
I need to connect yet another DVI monitor. I took a HDMI<->DVI cable, connected it to the onboard HDMI port. the monitor was not detected.
I tried various combinations of monitors and bios settings in vain. Under no circumstances the HDMI port drove the DVI monitor.
The cable is working fine elsewhere.
What did I do wrong ? Is there something I need to buy/replace for this to work ?
