Question / Help 16:10 game input for a 16:9 stream output?

[YouGotTheTouch]

I have a 16:10 (1920x1200) monitor, but streaming or recording in that aspect ratio would leave black bars at the side for most people. I had the simple idea of taking a 16:10 input and outputting a 16:9 stream/file with a small overlay at one side. This would give people something other than black bars, and could even make a webcam less intrusive.

This is all on a 1 PC setup, with no capture card.

So I had a look at the settings to see if there was an obvious way of doing this. I ended up changing the Base Resolution in the Video settings to 1280x720 and set up a scene with a Monitor Capture. It worked exactly as I expected - the 16:10 desktop sits nicely to one side in the 16:9 output window, with space for an overlay at one side.

But when I added a Game Capture, OBS simply took a 1280x720 image of the centre of the game window. This misses 60% of the game pixels, and is also the 'wrong' aspect ratio for an overlay.

Is there a simple way of getting OBS to see the game window in 16:10, the same way that it sees the desktop? I'd really prefer not to have to run games in 1080p because my monitor stretches instead of mapping 1:1, and I'd also prefer that people viewing my vids not have to put up with black bars at the side (not that anybody will be watching, but y'know).

Right click your source and fit to scene, or edit scene and resize / move it manually.

Everything fits into the preview window perfectly.

After a little more playing about, I think I've figured out the problem. Below is an image showing what's going on. After changing the Base Resolution to 1280x720, the red box for the Game Capture source (which snaps to the edges and all that other fancy stuff like every other red box) encompasses the centre 1280x720 pixels of my game. But the actual viewable size of the Game Capture window is still 1920x1200 pixels.

So I can fit the game window in the way I wanted to, but I have to adjust the borders manually, after tricking the OBS preview window to show the full window by alt-tabbing into and out of the game while Show Preview is active.
