Problem with red color

[Anexus]

Hello, I need help from experts...

I changed my old laptop for a lenovo legion with rtx 4070 a few months ago.
I am using two new Optoma zh450 laser projectors.

Since then I can't get a true red color on my projectors when using Arena generated content. Instead, it looks more orange. (New composition, new production, no effects).

If I play some videos in VLC, the same videos in Arena, or go to a website, the red on the projector is correct, so I rule out that the problem is in the PC or the projector.
But if I open a new composition and load a solid color or completely red lines, it doesn't work correctly, it shows orange, but definitely not red. It happens too in preview and comp monitor, I see orange instead of red.

Any idea what could be going on? No hue rotation or any other effect applied.

I don't know much about color spaces, gamma etc, so I usually don't mess with this stuff.

Thank you guys!

Is it also orange in the composition preview?
How about the advanced output's output transformation?
