user32008: I'm new to OBS Studio and have just recorded a video.
Once the recording completed, I realized that the produced video was not in full screen.
There is a blank area mark with X as shown in the screenshot below.

I only noticed this issue when I replayed the recorded video with VLC.
How do I fix this problem?
I would like to record the video in full screen, not half of the screen size.

user-1: Right click on the blank area > Resize output (source size)
