I currently have my laptop connected to a desktop monitor. I made sure that the laptop isn't mirroring the display onto the monitor. So only the monitor displays whatever I'm doing on my computer. But the monitor uses my dedicated GPU, and since I have no need to use the integrated graphics, I disabled it in the device manager. But now my laptop's display isn't "blacked out" like it normally is, now it's on.

So my question is, how do I disable the integrated graphics without the laptop display turning on when it shouldn't be?
