Hi,
I just installed Windows 7 on a computer running the Asus P8H77-V. I installed the Intel HD Graphics driver and ran all Windows updates.
My problem is that I want to drive two NEC AS221WM monitors using the graphic outputs on the Asus motherboard.
My problem is that as soon as I set the resolution of both monitors more than 1360 x 765 output appears only on one of the monitors.
How can I fix this please?
I'm attaching the System Information
