Windows Server - Headless WSH Box: How To Set Desktop Size?

Without a video card in this PC, RDP thinks the screen size is
some rather large dimension (as in 1900 x 1200) and the RDP
window becomes inconvenient.

Anybody know how to change it to something like 1024 x 1200
without a video card being present?

It seems like might be picking up the size from the default
monitor of the PC that is running RDP.... but the zinger is that
Display Properties | Settings | Screen Resolution's control
starts at 1920 by 1200 and only goes up... not down - and also
does not respond to user input.

Got it.   it is a setting in the Remote Desktop Connection dialog
that pops when one right-clicks the RDP shortcut and selects
Edit.

Display | Remote desktop size
