I still have my old RX 580... but that might be a bit overkill (also I only have 750W PSU, would that be enough?)
All 4 ports on my VII work fine, it's just if I connect more than 4 displays by means of daisychaining, things break (as described above). Do you believe that to be something I could solve by patching the framebuffer, instead of using WeG?
I have already gone back to headless mode.
If your power supply is from a reputable company, I think 750W should be fine for powering the RX 580. I currently have a really crappy 400W powering my Vega 56 (which is really power hungry) and haven't had any problems even when gaming.
I think using the RX 580 is a much better idea than trying to use IGPU for display when you have dGPU(s) installed. As stated earlier, it's unknown how macOS will behave with this configuration.
