Do any operating systems support tipping a monitor
so that the long side is vertical instead of
horizontal?

It occurs to me that editing code would be more
convenient if you could display more lines rather
than supporting longer lines.

Thanks. Paul.

Yes, but my (builtin adapter) "card" doesn't.

Certainly Macintosh took that approach with DTP.

Bah, and indeed, Humbug.

Yes, but only for newer OSes.

And the capability relies heavily on the display adapter.

So, if a display adapter doesn't support display rotation, the functionality
will appear disabled or not present in the OS setting.

I agree. Us humans, have more problem reading text with few but long lines,
rather than many but short lines.

The fact that widescreen monitor are often used in horizontal orientation is
mainly meant for video viewing. In that orientation, for text, it should be
used to display short but bigger lines, rather than long but small lines.
For professional publishers, the ideal screen orientation would be vertical.

Why can't the OS do the rotation logically itself?

Because that process is pretty computing intensive where it's best left for
hardware. Otherwise it won't left much free CPU time.

The closest thing to simulate the CPU time used for the process at software
level is to use TightVNC server+client application to connect directly to
itself (to `127.0.0.1` or `localhost`). Use it to display the current screen
in at least 60fps (set screen change detection rate to 17ms in the server
setting) without any kind of image compression (set image type to `Raw` in
the server setting), and scale the display down to e.g. 75% to simulate the
CPU time used to rotate the screen. Move the VNC display window around while
monitoring the CPU usage.

Why wouldn't an OS be able to ?
It may be a heavy delaying story if you try this with software ...

But if your OS is a standalone and hardware oriented then it's no big
deal to modify some graphic-modes and let the hardware act as desired.

Smartphones do that. Decades ago, there was a
monitor you could rotate between landscape and
portrait. I don't recall anything else about it.
It might've been the one Kerr-Mudd John mentioned.
