Using my 21" Trinitron OSD, I can see that the resolution at boot is 720x400.

From memory, this weird resolution is extremely uncommon if ever to be seen as a choice on software that supports different resolutions, e.g. 640x400, 640x480 or 800x600 to name a few.

So why does this screen resolution exist yet is rarely used but at boot?
