Question / Help Mass Effect 1 only appears in corner when trying to stream

[Dudica1]

Hey i'm trying to use OBS to stream on Twitch and I really want to stream Mass Effect 1 but when I try to stream it, the game only appears in the top left hand corner on stream but looks fine on my monitor, OBS works fine on other games (Only other game I really tested was Stardew Valley but that was fine on stream).
If anyone has an idea what is happening, please let me know!
I've included a log file, but I don't know if it will help or not.

Can you provide a screenshot of what you are seeing? Both the OBS preview window, and the stream output?

Here is a picture of the OBS display, i'm afraid I do not have two monitors so I cannot take a screenshot while the game is active

Select source and press CTRL+F (Same as right click Tansform Fit to screen)

Never mind that was the picture of how the game looks on stream.
This is the image of the OBS display, my bad
