PC + Receiver Setup. DVI for video to Monitor. HDMI to Receiver for Audio at the same time.

[Senshin]

Hey, all! I am looking for help from you audio tech's and PC tech's out there!
My monitor: Asus vg248qe 144 hz
My receiver: Denon 5.1 setup
My GPU: Radeon RX480
Window 10 64 bit
Monitor connected to GPU via DVI (HDMI does not support 144hz), the receiver connected to GPU via HDMI.
Right now, I duplicate them but there are some negatives:
-Can not use 144hz, only 60 Hz max.
-GPU works for both monitor and receiver so it's bad.
My monitor is 2.1 and receiver is 1.1 in the display setting.
Is there a better solution for me?

Thanks in advance for your time!

What motherboard? Does it have an optical audio out?

Gigabyte Motherboard, it has hdmi port but when I connect to the receiver. PC doesn't recognize it. No sound at all.

Did you try selecting the HDMI as your audio device?
It might not let you do that without a display connected to the receiver. You could try connecting a TV to the receiver if you have one around,
Or use digital audio output from the PC as suggested. You can get a card or a USB external one
