Fullscreen capture? Also no sound on desktop

[MMaRsu]

So i bought a cheap Chinese USB Capture card that lets me capture 1080p at 60fps

Now is there no way to actually watch the incoming feed in fullscreen?

Im using streamlabs OBS by the way

Like how am I gonna capture playing Ninja Gaiden when I can only see about 50% of the screen space?

Another question, im not getting audio on my PC. At least, not when playing. I recorded some NG2 footage and the sound is there, but when Im in windows looking at the screen in OBS, the sound bars move but I dont hear anything.

Anyone know a way to fix it?

I fixed the audio issue! Now I hear the sound on my PC :D

But is there a way to go fullscreen during capture?

Ok I just decided to go with windows magnifier lmao.

I have another question, when I use Listen function so I can hear the game volume while playing on PC, it creates an echo in the recording.

When I have this feature off I dont hear any audio, but there is no echo in the recording..anyone know?
