Doc update, section 3.2.3. Changing Console Video Modes

[Valzant]

Hello.

I am new to FreeBSD and I've been following the manual to get everything
setup but I ran into some errors in section 3.2.3. Changing Console Video
Modes.

On the forums I found a post with my exact issue and solution:

Maybe this section needs to be updated or removed ?

I am using 12.0-RELEASE, r341666 GENERIC amd64

Thank you!
