Edit: I’m glad so many of you have had no issues with multiple monitors. My set up is a little unusual (3rd display is an infrequently used large tv hooked through the receiver) and is definitely solveable but will take some effort (and honestly, I’d rather spend my spare time outside or with friends, so who knows when I’ll fix it.)
I have trouble getting real displays working all the time…
Needing to know which serial port is which and manually tellling the kernel via console=ttyS0,115200 or whatehaveyou is annoying…
What other displays could people mean?
That’s a job for your bootloader
