I have tried to connect my Projector (HDMI) to the motherboard's Display Port, and it come out another display 2, because it has no signal and then I clicked Detect button, it come out with Another display not detected, and I clicked Try to connect anyway on: VGA...

Finally, when I restart my PC, it only remain 2 diplays, which look like the attachment....
I do not know how my PC can detect that Mobile Display...and I do NOT have such device...even I unplugged the cable between my project and PC....

Now I only use HDMI cable to connect my PC to my Samsung monitor, but that Mobile Display still there......How can I remove that..

Also, How can I use Display Port to connect to the HDMI port of my projector, I bought an adaptor...but seem doesn't work.....

Click on the Multiple Displays drop-down arrow and select [Disconnect this display], as pointed to by the red arrow in this screenshot:

Probably a bad adapter. I've used this adapter with no problems:

The above is a passive adapter. An active adapter may work better for you and I've used the following active adapter to get three monitors to work simultaneously on my laptop:

Also, rather than an adapter, you may want to consider a DisplayPort-to-HDMI cable. I've had excellent results with this one:

No. Cable is passive.
