I just bought a SAPPHIRE DUAL-X R9 285 2GB GDDR5 OC (UEFI) card to use with PLP using my Dell 2007fp+3007wfp+2007fp.
When I go to create an eyefinity group, the 3007wfp keeps changing to a low resolution (1280x800) instead to the required 2560x1600. The 3007wfp is connected to the top DVI-DL input and is using a DVI-DL cable.
Please see attached pictures of CCC and Display Properties.
Any idea on how to get this setup to create a 4960x1600 Eyefinity group?
