Swapping HDMI ports

maschine

Hi there. I use a rather bulky HDMI to microHDMI adapter plug, which interferes with the USB-C power plug. Is there a way to swap default video output to the other HDMI Port? Thank you!

There's no explicit configuration for which HDMI port (on the Pi4) is used. Just power down the Pi, plug-in the adapter to the other port and then power it up again.

@mitu Thank you. I tested that again. While the boot screen pops up as expected, the screen turns black when normally the splash screen starts playing.

Do you have a video set as splash screen ?
What's the output of systemctl status asplashscreen ?

Yes, I have a video set as splash screen. This is the output:

Looks fine - it reported that it played the video fine.
Can you add more details about your setup ? I also use the 2nd HDMI port and I don't have a problem showing a video - I usually have a splashscreen image shown, but switching to a video plays it plays ok.

@mitu Thank you for your ongoing support to the community, much appreciated. I just learned that you do not support 3rd party images, which I fully understand. And honestly I have not created this setup on my own, as my knowledge is very limited. However, when I try a fresh install, everything works as you described.
