GTX1080 HDMI v Display port - separate audio/drop out questions

[sunshinewelly]

I am currently having some drop outs with my pc. I have my pc connected to my Amp - my amp is then connected to my TV and also my projector. All other devices including xbox x do not cause a drop out and also i get no drop outs to my projector

the drop outs occur with my pc running into my sony xe940 TV.

my cables are mounted behind my walls (the main one from amp to TV)

however my gtx1080 has one HDMI output and a couple of display ports. I was wondering if its possible to use the display port on the gtx1080 and send the video to my TV (using a display port/HDMI adaptor) and using the existing HDMI to my amp just for audio.

alternatively it may be possible that my HDMI output on my pc is somehow not working with my TV - would a displayport to HDMI adaptor still carry a full bandwidth ie RGB and HDR and audio.

Sure, its how I have my PC / AV system set up.

Displayport to the monitor from GPU's displayport. Then another direct cable from the GPU also via HDMI to the AV receiver. Works perfect for me and has done so for a few years now (with various nvidia GPU's I used it with including 1080).

A phantom monitor is created to represent the AV receiver, but that's a non issue really.

I have the 49" version of that TV connected to a Yamaha RX 483 amp. Are you having drop outs of both Audio and Video ? is there any particular time when using the GTX 1080 it drops out or is it random ?

I've used both DP cable via HDMI converter and a native hdmi port on card while I don't get drop outs sometimes randomly the TV will react like the resolution has displayed (with the overlay at the top)

cheers for the replies. Does having a phantom display (av) effect the cards power as i assume it now powering 2 displays or is the effect negligible.

how do i actually set this up is it dual display or just mirroring.

it seemed to start quite recently so not sure if its my lead that goes from my pc to amplifier.

its the picture only - audio is fine

its handy to know that i can do that though with the GPU

For the former its negligible, can set it to Duplicate in which case impact is non existent. I had problems with that now and then with my AV receiver so set as extended desktop and no problems since. Just set the phantom monitor as 600p for sake of it, though for gaming etc on main screen, trying with AV receiver (hence phantom monitor) attached or unattached resulted in no difference in FPS.

As to setting it up, it does it automatically with Windows. Will recognise your AV receiver as a second monitor. Can however just like selecting the sound outputs select the AV receiver.

cheers for all the advice. I changed my HDMI lead and now everything seems ok.
