I have a vsx-80 and 90 I just got the 90 to replace the 80 for Dolby atmos. I took my 80 and put it in my pc to replace a older pioneer that I used to run the huge speakers on my gaming comp. The hdmi on the 80 worked fine on my TV and my ps4 ps3 Yada Yada etc. I hooked it up to my big gaming monitor and hooked it to my Nvidia 970 Gtx and the reciver does not like the card at all it won't send the signal through the reciver to the monitor. Has anyone ever had this issue or attempted this? The card sends signal fine hdmi directly to the monitor. And I can hook the monitor to the reciver and that works fine. It's just when I hook the comp to the reciver the reciver says nope. I mean not a huge deal I am using optical cable for the sound I figured whatever right use hdmi and use the features on the reciver..
