I have my computer (video card GTX 770), receiver (AVR-1912) and TV (LG OLED65E6V). I have several HDMI and DVI-to-HDMI cables. I have connected the PC and the receiver via HDMI and PC and TV via DVI-to-HDMI. I want 4K video and 7.1-channel audio. For some reason I have not been able to get any sound from the computer through the receiver, only directly to TV, but only stereo.
It would be ideal to either duplicate the "displays"(receiver and TV) or use only the TV. Using only the TV seems to disable the option to send audio to the receiver. Duplicating the displays for some reason keeps the receiver silent.
Is it so that because 1912 does not understand 4K video signal, it does not accept the audio either?
Before I bought this TV the same setup worked fine with my old 1080p TV.
