Getting 1440p resolution from display port with hdmi out of it

post #1 of 6
Thread Starter 
I only find 1080p compatible adapter but I need 1440p.

Trying to do:

Send audio from my graphic card to receiver and trying to send 1440p video to my monitor.

Issue

I'm sending audio through HDMI and sending video through my D-dvi port. It shows my audio out as another monitor and I need to eliminate this or this won't work. So I MUST have one source to output audio and video.


Solutions:

Some type of software for HDMI from the graphic card to JUST send audio and not display?

Is there a adapter to send audio and a 1440p from the display port? (HDMI doesn't work since the graphic card is NOT HDMI 1.3 compatible and doesn't have the necessary bandwidth capabilities).


What I don't need to hear:

Why not run usb out, sound card or use the onboard SPDF out?? I need to support MULTIPLE PCM and is ONLY done by HDMI witch supports the bandwidth needed for it. Not only that, it is far superior to on-board audio because the digital out is outdated.


Graphic card:

GTX670 FTW

Reciever:

Onkyo TX-SR805

My only option is HDMI out from a mobo or add in card?

HDMI sends the signals in digital, in 60 Hz (or whatever), and the audio parts are placed between the video parts so a simple adapter would not work, it needs a circuit with processing capabilities. You need an HDMI audio extractor. They're not cheap.

These have pass-through HDMI ports so you can have an output as well, but some of them they will reconstruct the signal themselves so be sure that they're 1440p compatible.

This is done. Got my answer, but isn't what I wanted to hear -_-.

Bumping an old thread because I have the same issue and was hoping if anyone had any new ideas.

My previous monitor was a 1080p 120hz. I was able to run HDMI to my receiver and DVI to my monitor. In nvidia control panel I was able to clone the display so that there was only one desktop, and this worked perfectly. However I recently got a 1440p monitor and this no longer works. Nvidia panel refuses to output 1440p while in clone display mode. It does work in normal 2-display mode however. Currently I am running with a phantom 2nd desktop which works OK but is frequently annoying when icons/windows/mouse cursor disappear.

So, is there still yet no way to get multichannel digital audio out to a receiver without having to have to display outputs? Or at least to disable extra phantom desktops which are actually just audio receivers? Note that I find DTS connect over SPDIF to be unacceptable due to the horrendous audio delay.

Yay there's more of us people using receivers ^^&^^ Sadly i don't believe we can audio out to receiver without it being a display unless you wanna use cruddy spdif. Just do what i do with my receiver, put it in corner so you don't accidentally move cursor to it. Alot less hassle then cloning display etc.
