I have Nitro v15 which has "Thunderbolt 4" and "HDMI". And I have 2 external monitors.

I have a dock connected to Thunderbolt. And I have two monitors connected to the dock. Everything works perfect. It's my office setup, actually.

And one of the monitors above supports 144 Hz and it is connected to the HDMI port over the other input port. This is for gaming. When I play a game, I just disable all displays except this.

There is a problem here in my gaming setup. When I open a game, within 1-2 minutes, I hear blink sound, and the laptop screen gets enabled in duplicate mode. If I unplug the dock (Thunderbolt connection), it's fine, I can play a game without any problem. But if my dock is connected, somehow, the laptop screen gets enabled.

Do you know what the reason is?
