Quadro T1000 Monitor issue

Hello all,

I’m facing an issue with 2x Quadro T1000 card. In the company that I’m working for, we trying to use 8 TV in 2x Quadro T1000 graphic card.
There is just one TV that can’t reconize in this desktop. (It’s a Lenovo P360 running windows 10).
all the the 7 monitors works fine, but 1 of the isn’t work.
I already check cables, display port adaptors. Everything works fine. It just port 2 from the left to right isn’t reconize the TV (LG 42LN549C).
Do you know anything about it?

Does this problem move with the screen (other screens works fine on this port, using the same cable), or stick with the output (any screen with any cable does NOT work on this port)?
Trying to figure out if this is something specific to this very TV, or might be a damaged connector on the GPU…
