Would appreciate your help. Trying to add a 3rd display to my setup, but system is not recognizing it. Details below. Any ideas what's wrong?
AMD HD 7800 (driver just updated to latest)
Windows 7 64 bit
Motherboard ASUS P8Z77-V PRO
- Two NEC 2090Uxi displays connected via DVI
- 3rd display is a Dell which connects fine when I unplug one of the NEC monitors and swap in the Dell via DVI, but system doesn't recognize the 3rd display when I plug it into the graphics card Display Port slot (using DP2DVIS DisplayPort to DVI Active Single Link adapter to make use of the DVI input on the display)
