Im trying to get uncompressed audio to a 7.1 receiver. to get this i have to use the HDMI port for bitstream audio. (sounds cards cannot accomodate)\n\nHowever, i was wondering if its possible to use the displayport for my asus pg279q and keep the benefits of 144hz @ 1440p for video, while using the HDMI port for audio.\n\nThe issue maybe is that HDMI doesnt just send audio, it sends video too.. so would i be having a ghost monitor and will it affect the performance from the display port? AVR receivers are typically 1080p and do not support high refresh rates but have better DAC's. its to my understanding that if i had a ghost monitor set up then the graphics card will downscale the displayport performance to match the lowest in the chain... reducing my graphics to HDMI potential.\n\nif this cannot be done, would it be possible to get a second graphics card to act as an audio passthrough via HDMI to get the desired results? if so, will i be able to use any card or will it have to be the same as the one im using in SLI? im not sure if you can SLI different cards. \n\nAll the above is an assumption that i cant verify, just bits of information gathered with some theory solutions thrown that i cant test myself.\n\nHopefully you can clear up these questions and provide me the best\/nearest solution to getting uncompressed audio to my receiver.\n\nmonitor: Asus PG279Q - HDMI, DisplayPort, USB3.0 x 2\nmotherboard: Asus Maximus X code - 3.5mm, Optical, (HDMI)\nGPU: EVGA 1080ti FTW3 - HDMI 2.0b, DisplayPort 1.4 and Dual-Link DVI \n\nDenon AVR 1911 - HDMI, RCA, Optical.
