    First of, I fixed the black background by changing the background image.

    This was the previous configuration:
    Monitor -> DP -> GPU
    Receiver -> HDMI -> GPU
    Monitor and receiver were not connected.

    The problems were:
    1) After each restart it failed to recognize the receiver as the default audio device until I opened the Windows audio settings;
    2) The second desktop was smaller;
    3) Issues with screenshots since there was a desktop extension;
    4) Bug with the black background indeed.

    Then I tested:
    Monitor -> DP -> GPU
    Monitor -> HDMI -> Receiver
    Receiver -> HDMI -> GPU

    With this configuration:
    1) It automatically recognizes the receiver as the default audio device when I turn it on;
    2) The second desktop now has the same size and I can now make the desktop mirror.
    With the desktop mirror there are no problems with screenshots nor with black background.
    Since my DisplayPort is 144Hz and my HDMI is 60Hz I tested on https://www.testufo.com and it was using 60Hz so I switched back to desktop extension, although v-sync does not lock fps at 60.

    According to the G-SYNC indicator the G-SYNC is ON in all three cases.
    A little problem is that the Windows Audio Control Panel recognizes two receivers and sometimes they switch with each other.


    @Chastity
    Two questions:
    1)
    I don't get this one.
    2) Would making the second desktop with a low resolution (800x600) help performance?

    If you mirror the desktops, then settings will match, and if one of them is only capable of 60Hz, then they both will. So if you want 144Hz, you'll need to not mirror. (When I did it, I had matching monitors, so everything was in sync.) Also seems your receiver is limited to 60Hz.

    Best option is to extend desktop, to keep 144Hz, and edit screen captures of the desktop with cropping.

    The problem is that V-Sync locks fps at 144 not 60.

    Could you answer the two questions please?

    1) When doing the extended display, and not using a 2nd monitor with the receiver, I like to set up the unused area of the desktop diagonal to my normal desktop area so that the borders do not allow the mouse tro travel off screen. Like in the pic I showed earlier.

    2) The display area of the 2nd area if not connected to a display would be irrelevant, and not affect performance. If you do use a monitor, just use the native resolution. It doesn't affect gaming performance of the 144Hz screen.

    Ok but I still don't get why the v-sync with mirror locks fps at 144 and not at 60 since it uses 60Hz.
    Btw if you mirror, should you sync the graphic settings of the second desktop or doesn't matter?

    I suggest you experiment on what works and what doesn't at this point.

    Since FreeSync works over HDMI, can it work with a Home Theater? Obviously I mean without the double desktop.

    @Chastity Anyway I noticed that if I turn off the A/V receiver while playing the screen freezes, it can be a problem with a blackout, I have a UPS for the PC but not for the speakers.
    Would it be ok if I restart the PC from the reset button on the case and then turn it off from Windows?

    If it locks up due to that just keep the receiver off, then restart the PC.
