I need to have three monitors on a Dell Optiplex 780 without having to use a PCI adapter.
If you plug in a PCI-E video card, other than those expander cards, it disables the integrated video.
The cards we bought are PCI-E and only themselves support 2 monitors without using an HDMI-to-DVI adapter. Testing that now, not even sure these will do three monitors with that setup.
Any non-PCI recommendations welcomed.
