I just upgraded from Gigabyte GTX760 to Gigabyte GTX980 but the DVI-I port does not recognise my second monitor. DVI-D port works fine with both monitors and GTX760 had no problems at all. Both monitors are Iiyama ProLite B2480HS.
Details:
Model: GV-N980G1 GAMING-4GD (rev1.1)
BIOS: GV-N980G1 GAMING-4GD_P.f40
OS: Win 8.1 64-bit
Driver Ver: Nvidia 347.52
Motherboard: GIGABYTE GA-Z97X-UD3H
Anyone any ideas?
