Hi - I've just downloaded OBS, followed a basic tutorial and...nothing. I've set up a 'display capture' and all I've got is blackness in the preview screen; suffice to say, nothing but blackness is recorded when I record. I assume I'm missing something fundamental in the setup, but having gone through all the settings multiple times, I'm at a loss. Thanks in advance for any help. Oh, and I'm running Win10 on a very new and powerful gaming laptop (though I'm not planning on recording any games, just desktop stuff). Cheers, Max
