Problems with HDMI and Windows 10 *
https://www.avforums.com/threads/windows-loses-connection-with-onkyo-tx-sr393.2361024/ I have been using an HDMI solution for my Windows10 PC for a few years now. On the whole it works fine. I had a period when the connection was a bit buggy but that turned out to be an HDMI cable....works fine now after cable change. I do not use HDMI for video, as I find it sub standard. I use a 4K monitor, instead I connect via a Display port which in comparison to HDMI is far better. BTW what GPU do you have as that is another possible problem area. If you only need 5.1 you may be able to try an optical cable just to see if you have better stability. My GPU is AMD RX480 which is about 5 years old I guess and it is quite a good 4K GPU. Not used NVidia so cannot comment. Be interested to hear your comments.
