Chuwi ubox second monitor not working

Hi, i am trying to connect second monitor on dp output, but it doesn’t work at all, that second monitor and wire is working fine in other computer so it seems chuwi ubox doesnt support second monitor, my dp is not working, or i need to change something, could someone confirm chuwi supports 2 monitors? and if so… how?

many thanks.

fixed, i had to change wire, but it is working with other computer… no idea what happens
