The window in your screenshot is a custom window with id 1101
you can activate this window directly with ActivateWindow(1101)
BUT the window requires properties to be set
you can see the operations performed by the skin when you click the gear icon

it sets 2 properties then activates 1101
currently, to the best of my knowledge, there is no way to map multiple actions to a single keypress
the result is opening an empty window, you can check the custom 1101 file to see where it is using the properties to include and to set the window title

so there is no way to open this directly from a keymap
-----
1 way to achieve this exact result would be to create an addon to do it for you then map a key to run that addon
-----
if that is not an option then you can map to specific settings windows instead of the menu
- ActivateWindow(osdvideosettings)
