I have a new Inspiron 3656 with a Radeon graphics card. I would like to connect dual displays; one via Radeon HDMI port and one via built-in HDMI card.
Radeon port is working fine, but I can't get the built-in HDMI card to work. I can't even find reference to it in Device Manager or BIOS. Is it a faulty card or am I missing a setting somewhere?
When you have a discrete card, the built in one is disabled. You need a videocard with dual ports to have dual monitors.
