Can’t Delete Outputs from Xrandr

I was trying to use my android tablet as a second monitor as shown here: Using an Android Tablet as Second Monitor via VNC. Then, I made some mistakes while solving the problem. The mistakes which I did: – Created more than one output, in the section below you can see it,

VIRTUAL1 connected (normal left inverted right x axis y axis) 1368x768_60.00 60.00

VIRTUAL2 disconnected (normal left inverted right x axis y axis) 1280x800_60.00 (0x22b) 83.460MHz -HSync +VSync h: width 1280 start 1344 end 1480 total 1680 skew 0 clock 49.68KHz v: height 800 start 801 end 804 total 828 clock 60.00Hz

mode_ipad (0x241) 63.500MHz -HSync +VSync h: width 1024 start 1072 end 1176 total 1328 skew 0 clock 47.82KHz v: height 768 start 771 end 775 total 798 clock 59.92Hz

I created these three virtual monitors by mistakes but, only VIRTUAL1 output shows up in the System Settings –> Displays.

Even I tried to close it with:

xrandr --output VIRTUAL1 --off 

It still shows up itself on the displays section.

Can you help me deleting these virtual monitors? For any help, thanks in advance…
