There certainly are invisible differences between Linux and Windows kernels internally how they implement HDMI signalling. So it is possible Linux is more fragile than Windows in this respect. As such, avoiding the receiver or changing cables might be a workaround.
A proper fix in that case would go in the kernel so reassigning there... ** No longer affects: xorg-server (Ubuntu) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1926032 Title: [i915] Screen "disconnects" when updating screen buffer Status in linux package in Ubuntu: Incomplete Bug description: I have a problem in which the screen will behave as if I pulled the HDMI or turned the computer off (no source) for a few seconds until the screen comes back on again. This happens a lot when I open a new window, moves the mouse after it has been still for a while or I open a new window or move the current window. I can watch a whole movie without this problem but as soon as I pause or touch the controls of VLC or move the mouse the problem reocurr. It seems to be after a certain idle period most of the time, but not always. Sometimes it happens many times in a row. The setup is my home built media PC with intel integrated graphics (i5-9400) connected to a philips 55" TV (55POS901F) through a Pioneer AV receiver. I have tried probably every possible resolution and screen update frequency and the problem is still there.
