Hello, I'll be breaking years of lurking to answer this question that's been on my mind all week...
I have a 4K Television @60HZ 4:4:4 RGB over HDMI from my GTX970, this works great, I have almost no issues except gaming at 4K.
However, for years I've been using an "ok" receiver, and have been happy with Optical DTS Interactive/PCM24/96hz. I want an upgrade to match the television experience, but the receiver I will be given as an upgrade sadly only have 1.4a, which has ARC, as well as HDMI Uncompressed audio, but how do I even get to take advantage of that? The receiver probably won't allow me to input a full 4k signal, nor would it passthru the video to the TV, how can I achieve this HDMI audio without the use of having a "second monitor" via the nvidia control panel that either gets in the way, or will slow down, or mess with the cards power scaling. As far as I know, ARC is not possible, as it's essentially the same as Toslink... (whyyyyy????)
I have contemplated a few ideas, but have yet to test them till I get the AVR, one is to have the HDMI directly to the TV, and use the DVI port with a HDMI adaptor and pass the "second monitor" to it, and find someway of having the screen completely ignored as much as possible. Or, purchase/reuse an old nvidia card to pass HDMI directly to the AVR without it affecting performance.
Now I'm not entirely sure, but I can't say for certain they'll work as I don't know if: 1. DVI to HDMI supports DTS/Dolby TrueHD and 2. If having a second card purely as a monitor and sound output would work and alleviate resources from the already limited GTX970.
I'm sorry if this was more appropriate in "Graphics Cards", but I felt other people who took audio seriously would have more likely encountered this issue seeing as 4K is readily available, and plenty of people don't wish to upgrade their receiver just yet.
Thank you so much, and I hope I manage to clear some of the dread of not being able to hear uncompressed audio. (Have a serious ground issue with my house, and 5.1 Analogue is out of the question).
