m91p displayport issue

2016-07-22, 11:49 AM


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.

What is the make and model of the DP adapter?   When you write that VGA worked great, was that to the TV?

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.
