Black bars on around KSP

I moved my KSP window to view it on a monitor, but it put black bars on the side of KSP.

Screenshot please?

You probably need to change the game resolution to fit the monitor rather than the other screen (laptop?) you had it on before. Main menu > settings > graphics and change the resolution to match the monitor; you can find the monitor resolution on Windows by right-clicking the desktop > display settings.

I DOnt want to use it on the monitor due to low resolution, And I don't know how to upload an image other than Imgur
