Help with Muulti-monitor setup please

[Horrgakx]

Hi all - I'm struggling with my monitor setup and would appreciate some advice if anyone can help please...

I have 2x Asus monitors (32" 3440x1440 and 27" 2560x1440) connected via DisplayPort to my GTX980.
I also have an Onkyo amplified connected to the graphics card in order to provide 5.1 audio (I don't use this for a video signal).

The issue is that Windows thinks the Onkyo is another monitor but I don't want my desktop extended to it because as I said I'm using it for audio only and as you'll see from the screenshot below I have an empty space off to the side of my desktop. If I go into the desktop settings and try to clone the Onkyo amp to one of the other monitors then the other monitors take on the lower resolution of the Onkyo amp. Grrrr!!!!

(EDIT) - Of course some of my icons have now disappeared onto the 'other' monitor which I can't see 😞

Could be a lot of things. First ensure that the cable is fully seated. It should lightly snap into the port. You will need to select the proper playback device in Windows. Make sure to choose the digital output and not the normal output or HDMI. Windows 10 will only output one at a time. If the cable is seated and active you should see a pinpoint of red light visible on the opposite end of the cable.

As an Onkyo owner myself I know you also need to make sure that the optical connection is assigned to the input you are selecting. Consult the receiver manual on how to ensure this is the case.

Yeh thanks all of that was done, including firmware/drivers, didn't appear to make a difference.
