Audio Selection

To check the information on which sound output is used type:

cat /dev/sndstat

Example of command to choose the soundcard, that can also be inserted into /etc/sysctl.conf:

sysctl hw.snd.default_unit=0

Radeon HDMI audio out

Partially supported Radeon video cards, linked to in the section GPU Hardware, usually don't support HDMI audio out. Other Radeon cards require extra configuration.


GPU Hardware

Here is a list of FreeBSD supported video cards, https://wiki.freebsd.org/Graphics .

AMD

Many Radeon cards are compatible with FreeBSD.

Nvidia

Nvidia cards haven't always been compatible with FreeBSD, but recently they are and have video card support.

Multiple monitors

Use the program xrandr to be able to use and configure multiple monitors. With this program, a basic video card can use both of it's HDMI and DVI outputs for dual configured monitors.

Example of command line that can be used in the file .xinitrc:

xrandr --output DVI-0 --right-of HDMI-0

To see the obsolete way of configuring dual monitors for Nvidia cards, see Dual Screen
