Hi, First, before all, I tried to assign 4Gb of ram to my iGPU but still didn't succeed in enabling relive.
About the specifics of the setup. I have 3 HDMI monitors connected through my GPU. 2 of them are using DP to HDMI adaptors because my GPU only has one HDMI port. My main monitor, the one that I use for gaming, it's the one connected to HDMI. I cannot connect this one to DP, because there are some games that just won't work when playing with DP, like old Legos or NFS Heat.
I have another HDMI cable going from my iGPU to my Onkyo TX-SR606. The reason I do not connect my main monitor through this receiver is the model. This model has the specific problem of the graphics card starting to fail due to bad design and heat problems. So many times it just doesn't work first try. While I don't always use my surround system, as I have a pair of headphones too, it isn't necessary for my surround system to always work. This is not the case for my monitors of course. Also, even if it worked first try, right now i have a 1080p60 monitor, but I just bought a 1440p165 monitor. A resolution and refresh rate that my old receiver won't support.
These are the specifics of my situation.
