I have m91p and last week I tried to connect 2 screens one with VGA and one via DisplayPort (through dp to hdmi adapter) and every thing went well.
But yesterday I connected the DP to my tv and it shows "no-signal". I tried every combination and I still got "no-signal".
the VGA work great.
Both vga and DP are on-board outputs.

Same bizarre issue here. Can someone help please? Here are my details:
M91P 4480 with Intel HD graphics, DP and D-sub both on motherboard.
Windows 10 Home
DP output to DVI only works when the D-sub is connected. I happen to have both on my monitor, so I guess that's a good workaround, but even in the BIOS if I unplug my D-sub, the DP output drops too. Whaaaaaat?
I did look in the BIOS (which is up to date) and cannot find a setting other that PCI/IGE/AUTO for video output. For now, I can just choose the digital monitor in Windows, but it seriously thinks I have two displays plugged in when it is two cables to the same frickin display.
