Razer Ripsaw

Hey I just bought a razor ripsaw HD. I set it up correctly but when I looked at my tv the ps4 home screen was shrunk. I realized that everything was smaller on the tv and I couldn’t play without a smaller screen. I tryed to edit the size in the ps4 but that didn’t work. The only thing I noticed is that I can see the full screen of the tv on my computer with obs. How do I fix this so I can record while playing on the tv screen.
