RX 550 Rendering to a second non-present monitor

Hi all.

My specs:

OS Windows 7 x64 10GB RAM

Processor A4-4000

Video card RX 550 4GB

Monitor HDMI LG Ultrawide 25" 2560*1080

The video card thinks that there is a monitor on the DisplayPort, but I never used this output, and there are no settings to this ghost monitor, one month now with this video card and I can't even play games, because it keeps making a sound of a disconnected usb device, the screen blinks, the computer hang for some seconds, and then a sound of a usb being connected, the screen stop blinking and a ghost monitor appears on the monitor settings.

Even if I uninstall this ghost monitor in Device Management, it comes back after 3-5 minutes, making that annoying sound of usb, blinking the screen and locking the pc.

Making the video setup to only show the desktop in the monitor 2 (my only monitor is shown as 2) I can use internet, hearing the annoying sound of usb all the times that this ghost appears, but I cannot play games.

If I uninstall the graphic card drivers, it stops to appear and disappear the ghost monitor, but without these drivers the pc is slow.

Is there a way to delete only the driver of the DispayPort?

Is there a way to disconnect forever the DisplayPort output?

That thread did not help me. Its another AMD user with the same problem in a different OS with a different video card.

I found more, all unresolved:

RX 580 - 2 Users- 10 Days - https://www.reddit.com/r/AMDHelp/comments/8ck4xi/ghost_or_nonexistent_displays_detected/

R9 290x - 12/2016 - https://community.amd.com/message/2770722?q=ghost%20monitor

RX 460 - 7 Days - https://www.reddit.com/r/AMDHelp/comments/8dee4t/eyefinity_reconnects_and_disconnects/

And by the discussion, it is a driver from the graphic card. Using the generic driver the problem don't appear, using safe mode there is no problem.

So, the problem is laying down on the ******* graphic card driver.

I will dig more, come back later.

** Windows 7 and Windows 8.1 must be fully updated before attempting to install any AMD driver. All 'critical', 'recommended', and 'optional' (no language packs,etc) updates as well as any Service Packs (SP) must be installed before any attempt to install graphics drivers. If you do not get this message .... keep installing until you do:
