    AMD HD7670 4GB 128BIT DDR5, no video Dvi issue

      Hi, my desktop computer setup is windows 8 pro 64-bit

                                                             Pentium dual-core cpu E5400 2.70 GHz

                                                             6.00Gb Ram.

                                                             27 inch 2560x1440 Dual Link DVI-D port - main monitor

                                                             23 inch 1920x1080 vga port - spare monitor

       

      For my video cards I was running a PNY NVIDIA GeForce GT 620 1GB GDDR3 VGA/DVI/HDMI PCI-Express Video Card VCGGT620XPB and wanted a upgrade. So I bought a AMD HD7670 4GB 128BIT DDR5 VGS+DVI+HDMI PCI-E. So I deleted all device drivers for the GT 620 and installed all the new ones for the AMD HD7670. Swapped out video cards now I'm getting a blank screen from my 27 inch 2560x1440 but my 23 inch 1920x1080 still works perfect, my computer recognize that the 27 inch 2560x1440 screen is there, just no response from that screen. So what should I do?
