Hi!
My monitor doesn’t show anything through DP-1 after (I think) an update.
I use a TV (HDMI-2) and a monitor (DP-1) … sometimes one, sometimes the other, sometimes both at the same time.
I have looked many posts and I’m going to add the information I’ve seen that it’s important.

but it solves nothing, because it still shows “not connected”.
If I connect the monitor using the HDMI cable works OK.
If I connect the monitor using the DPI with other computer works OK.
So the monitor and the cables are OK.
Any idea?
Thanks in advance!
