Used to be, multi-head cards would list each head as a separate |
19 |
sub-device. I was surprised to find my GeForce 210 (which can support |
20 |
up to three outputs. One DVI, one {VGA|DisplayPort} (don't remember) |
21 |
and one HDMI) only shows one device. I know I saw it on some old AGP |
22 |
and PCI cards which had S-Video out. |

Strange. |

Anyway...if looking to drive more than one head off the same video |
27 |
card, keep in mind that DVI and HDMI are only an adapter apart. I've |
28 |
got a bunch of DVI<->HDMI adapters, and some are attached to the DVI |
29 |
port on a monitor (allowing me to use a computer's HDMI output with |
30 |
that monitor), and some are attached to the DVI port on a computer |
31 |
(allowing me to use an HDMI-only monitor with the DVI port on a |
32 |
computer). |

It's really not hard to find triple-head cards with DVI, HDMI and one |
35 |
of VGA or DisplayPort. Pretty sure I've simultaneously used all three |
36 |
outputs on a DVI+HDMI+VGA card, but I don't remember which card. Some |
37 |
only support driving two of those outputs at a time. |
