I can't get a DH87RL board running Windows 8.1 to do extended desktop across 3 attached displays. Extended desktop works for any 2 of the 3 displays but not all 3 concurrently. An error message "The display settings could not be saved. Please try a different combination of display settings". I've tried several recent releases of Intel HD Graphics drivers for Win8.1 with the same results. BIOS is the latest 0323.
Displays 1 & 2 are HP 2311f monitors (1920x1080) and display 3 is an HP w1907 (1440x900). The second 2311f monitor is driven through a DisplayPort-to-HDMI adapter cable that works great. The w1907 monitor is connected to DVI. Does anyone know whether DH87RL can fundamentally drive 3 displays concurrently, or perhaps this is a bug?
