I am playing on an Alienware laptop and I am not using an external display. When I load Forza I noticed the screen dimmed a bit so I checked my display settings and it showed a second display connected (there isn’t). I can fix it by selecting “show only 1” then clicking “keep these settings”. If I look at the display settings again, the phantom display is gone.
I have an NVIDIA RTX 3070 TI. I looked in devices manager and it shows two monitors (exactly the same). After I do the fix I mentioned above, device manager shows only one monitor.
