Bought a USB 3.1 Type C to displayport 1.2 convertor so that I can connect an extra monitor on my laptop.

My laptop already has a hdmi monitor connected but when I attach a display port monitor to the convertor. it says: No signal. When I turn my hdmi monitor off. The display monitor turns on and works good.

Is this normal behavour or can I do something about it so that the both work simultaneous?

Good day Jimbo123,

That would mainly depend on the capabilities of your laptop i would think.
Active adapters like CAC-1507 / CAC-1517 are sensitive to other active devices like for instance docking stations, but if there is no other active adapter/cable/docking is in use … then the issue must come from the laptop.
Please try setting the Screen connected via the adapter as primairy, and then connet the HDMI screen … see if that helps.
Which laptop you have (brand/type/CPU/Graphics)?
