Changing aspect ratio through launchbox

[Ikusagami]

Some of my games/emulators display only in stretched fullscreen despite being intended as 4:3.  I've found the best way to play them as intended is by going into Nvidia control panel and under"Adjust desktop size and position" checking "enable desktop resizing" to effect GPU and setting it to 1440 x 1080.

As I intend to eventually have the cabinet be a front-end only operation, my question is if there is some way to do the aforementioned Nvidia aspect ratio resize automatically through launchbox concurrently with launching a game? Like a batch file or something?
And probably the harder part, to have it automatically change back to native widescreen when the game is closed?

Any help is appreciated.

The best way is to set it in the emulator itself. Pretty much every emulator I have seen and touched has display settings to set resolutions and aspect ratio.

I meant specifically for those that don't or with which it's faulty.  I have to use several versions of some emulators for different games, and a few just don't respond to internal aspect ratio settings or lack them altogether. Likewise, using Reshade for Sinden Light Gun sets the border on fullscreen and I get (much!) better functionality having the game fit the border widescreen and then resizing the monitor/desktop to 4:3 than using bezels.

As I said, the Nvidia control panel method is fairly fast (and less faulty than resizing via the Noir's control panel), so I was hoping to find some way to automate it without leaving launchbox.
Best alternative I can think of if this can't be done is to find a universal remote that corresponds to the Noir's monitor and switch it manually, but it's black screened on me a few times doing this via the control panel and required me to switch the power off/on to get picture back (she's an old girl)--obviously not something I want to do once the computer is internally powered through the cab.
