USB to displayport works but not simultaneous with my external monitor connected with HDMI

3 replies

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)?

I bought 2 different monitors. With that the problem is fixed

Ok good to hear and thanks for the feedback
