OP2 Rasp Pi 4 sec display VGA

[dsanduril]

Haven't tried that monitor, but in general VGA requires:

Code:

[HDMI:1]
hdmi_force_hotplug=1
hdmi_drive=2
hdmi_group=2
hdmi_mode=16

 [HDMI:1] tells the config to only apply to port 1 on the pi 4, so put this section at the bottom of the file. If you have other required HDMI commands for your main monitor you may need to put them in an [HDMI:0] section (by default they apply to 0, but when you are configuring two monitors best to be explicit).

the hotplug command forces the pi to believe the monitor is connected, whether or not it really is (since it won't get a signal from the VGA port to tell it.)

the drive command selects between DVI (1) and HDMI (2)

the group command says "treat as a monitor (2=monitor, 1=TV).

the mode command is 1024x768@60Hz

depending on system you may also need:

Code:

enable_tvout=0
disable_overscan=0

these are both the default values, but sometimes you have to be explicit about them.
