With multiple screens a command prompt in fullscreen mode opens a copy
on all screens.
Is it possible to have a command prompt in fullscreen mode, but only to
open on one screen?
Thanks in advance
When you run a command prompt (or a DOS program) and set it to fullscreen
mode, it is given pretty much full control of the video. You won't get any
other program's display unless you run everything in windowed mode.
This is also true of DOS or Windows games that run in fullscreen mode
including ones that run under DirectX. I suspect that there would be even
more complaints if the game wasn't mostly in control. It can be an
annoyance if things happen like the mouse cursor not being restrained to
the fullscreen size (which still happens sometimes), or other windows
popping up during your game...
The maximized mode on a Windows program is just a window that fills the
full screen, and is not the same thing as a DOS program in fullscreen mode.
Try clicking the maximize button on a cmd window - it will usually resize
to fill the screen top-to-bottom, but not side-to-side, and will still have
the window borders. If you switch it to fullscreen via ctrl-enter, you
should see the difference.
You may be able to have a different maximized window on each monitor, or a
maximized window may stretch to fill both displays. This is a function of
the video card and driver. One machine I have with an Nvidia card allows
for either way of maximizing with the regular driver, and on my machine
with an ATI card I could add the Hydravision program to get the stretch
function.
On some video cards and monitors (when in fullscreen mode) you will get a
"clone" on all the displays, and on others you will get a display only on
the primary monitor while the other monitor(s) will go blank. You will
probably see the same behavior when the machine first boots up and is
displaying the BIOS screens.
For even more variation: on one of my machines, a fullscreen program fills
the whole display (and text looks bad as the aspect ratio doesn't match),
and on another, it only fills the center 640x480 area of the screen. I am
not sure whether this is controlled by the video card or by the monitor
itself. I think that for an LCD screen it may also depend on whether it is
attached via DVI or via analog VGA.
