Question / Help Windowed capture cannot be resized to fill whole window

[Dragon]

I have a problem. I decided to stream DOS game using DOSBox in windowed mode. A created source and set "Window capture". Then I tried to change the size of this capture, but solid black border is left. If I continue to change capture size, my window is cropped. Here is what I mean: http://i.imgur.com/4O0gH.jpg

How to make this region fill all the window?

Btw, I use Win7 x64 and OBS x64. Display's resolution 1600x900.

The best solution would be to change your streaming resolution to match the aspect ratio of your source (looks like your DOSbox window is 4:3, and your stream is 16:9 widescreen). If you absolutely want to stretch your source (deforming the video; turning circles into ovals, squares into rectangles, etc) you can hold down shift while resizing your source to scale freely.

Set your base resolution (in video settings) to the same resolution as your window if you would prefer not to have black on the sides.

Thanks.
Btw, it would be great, if there's an option to change resolution between 4:3 and 16:9 on the fly from the preset.
