How does the GT 520 auto-detect the connected the device ?

It has 3 connectors: VGA, HDMI and DVI.

What I want to do is:

1. Use VGA always for monitor.
2. Use HDMI only for audio connection to receiver.

Problem with this setup is that GT 520 believes receiver to be a
monitor and switches to it automatically on boot, with different/weird
results, either no screen, or bad screen.

The "manual override" is to specify what port is to be used for which X
screen.

Sorry, was in Linux groups for a while today. The Windows nvidia driver
can also specify with monitor to use for which output. You may have to
activate advanced settings. It been a long while. Just boot via VGA,
then plug in HDMI, and configure as needed.

Next, you will also have to check the BIOS for default video output. Not
all motherboards have this.
