Using my PC in a home theater and would like to send audio and video through separate HDMI ports

Go to solution Solved by chris7,

Press windows + P and select duplicate and you can send them same thing to both outputs.

 

There maybe other options using eARC too depending on the TV.

My receiver unfortunately cannot process 4k@120hz, it was the first gen that supposedly supported HDMI 2.1 but it turned out a lot of those early receivers used the same faulty chipset and it's restricted to 4k60. My workaround is to run an HDMI cable straight to my TV for video and a separate cable to the receiver for audio. This works... sort of. My PC (using a 3080 Ti) wants to treat my receiver as a 2nd display, so while it's great that the audio goes through my speakers, sometimes a window will open in my "2nd" display and I'll have to change inputs on my TV to view the receiver's input and move the window back over. First thing I tried was unplugging the HDMI cable between my TV and the receiver and that didn't work. I have found the Windows setting to ignore the 2nd display, but doing so just fully disables that HDMI port so I also lose audio.

 

I'm hoping there's a setting somewhere I've missed that can identify an HDMI port on my GPU as audio only so I no longer have a 2nd phantom display hiding things from me. The easiest solution would be to buy a receiver that actually supports full fat HMDI 2.1 passthrough, but I really don't want to spend $1k (or more, I haven't looked at receiver prices in years) to solve this problem.

I'm annoyed that I didn't think of that but very thankful for the help! Easy solution, things are working perfectly now. This is my first PC build and my first proper PC (been all laptops before this) and this was the last big thing I couldn't get sorted on my setup. Thanks again.

Ok bad news. I didn't realize this earlier because I was just focusing on audio and the phantom display, but duplicating the display limits me to 60 hz, I'm guessing because that's the most my receiver is capable of at 4k. I tried changing which one is the primary display and that has no effect so I'm right back where I started 😕

 

edit: I don't like that my emoticon is automatically turned into an emoji against my will.
