Xrandr and my laptopscreen

Heyas

I've been playing around with my script VHS and figured, "all of a sudden" (first time on arch, worked well on fedora/netbsd) it cant record no longer my screen.
Figured, when it was trying to get the screen resolution from xrandr, it was parsing for an asterix, now, my xrandr doesnt show one.

If fact, my current xrandr looks pretty strange to my eyes.
Another issue, which i guess might be 'related' is, that my when i play some old games on dosbox, the screen cant switch back to 1920x1080, not even manualy.
The xrandr did look the same, but since it was after the dosbox issue, i blamed that and didnt bother with it since, as i had my full hd back after a restart.

Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767
eDP1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 193mm
   864x486       60.00  
   640x480       59.94  
HDMI1 disconnected (normal left inverted right x axis y axis)
VGA1 disconnected (normal left inverted right x axis y axis)
VIRTUAL1 disconnected (normal left inverted right x axis y axis)
  1920x1080 (0x48) 140.000MHz
        h: width  1920 start 1968 end 2068 total 2100 skew    0 clock  66.67KHz
        v: height 1080 start 1083 end 1084 total 1110           clock  60.06Hz

First of all, the current screen res is not listed, neither is any standard between FHD and VGA (never seen that 864x486 before, if it was 854x480.. ok...)
Then further down, for the very first time ever, i am seeing that 'VIRUTAL1' item.
And for being disconnected, it shows quite a bunch of configuration.

Seeing the above output of xrandr, i wonder how i actualy got those 1920x1080?
The Wiki didnt help me, and thanks to the manpage, here is more information i dont really understand:

Guess this might be usefull?

When i tried to add a custom mode, it failed:

xrandr: failed to parse '1920x1080' as a mode specification
Try 'xrandr --help' for more information.

However, copying an example from the manpage worked fine:

        v: height  768 start  771 end  775 total  798           clock  59.92Hz

I'm looking at a virtual screen!?
I would had expected eDP1m specialy since the VIRTUAL1 one is disconnected...

Any idea or advice please.
(getting a regular listing, with the current screen res with an asterix (*))

Thank you in advance

Re: Xrandr and my laptopscreen

Issue remains, even after reboots.

Another thing confusing:

xrandr --listproviders 
Providers: number : 1
Provider 0: id: 0x47 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 4 associated providers: 0 name:Intel

However:

lspci | grep -e VGA -e 3D
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)
01:00.0 3D controller: NVIDIA Corporation GK107M [GeForce GT 745M] (rev a1)

Main question:
How do i get rid of the VIRUTAL1, which is ACTIVE, as in, that is my display, eventhough it is labeled as 'disconnected'.

Any ideas, please?
