Additional monitor displays showing black screen on OBS

I am using a Laptop (windows 10) as my main machine which is connected to the docking station and I have 2 additional monitors connected with this.

I hardly use my laptop screen for anything since my primary workstation screens are the connected 2 monitors to the docking station. Laptop is basically just to power everything.

OBS display is only showing my laptop display. When I select other 2 displays (connected monitors), black screen shows up.

I have tried doing the nvidia fix as well (graphic settings to use "high performance" option) but still no luck.

Can anyone please help?

From Windows 10 v1903 onward, GPU assignment is not done in the nVidia Control Panel any more. Microsoft made it so it must be done in the OS instead; here's a link to instructions on how to do that:

I include that as it's the most common cause/fix, just in case you tried a deprecated method before.

OBS can only capture from monitors connected to the same GPU it is running on. Normally the built-in display runs on the low-power/power-saving GPU to optimize battery life.
When it comes to external monitors or docking ports though, all bets may be off. Some run on the low-power, some on the high-power. Some USB 3.0 'docking stations' have a video card device built into them, and don't use any system-internal GPU at all (which would leave you sadly out-of-luck, as OBS can't be set to run on those). Port replicators have a much better chance of working, but the distinction between those and USB 'docking stations' can be muddy in the literature. Generally, if it connects to the laptop via USB, it probably won't work. If it has a custom proprietary connector, it has a much better chance of being a port replicator (which probably will work).
