So I just installed the final part for my new computer that I have been building, but I plugged it all in but it won't connect to the monitor. Everything is definitely on & running since I either see the parts running or a light is on them. I have an Asus rog strix b350f gaming motherboard & an Asus radeon rx580 4GB graphics card, I have tried using all the different hdmi ports on the pc & the monitor but it always just says 'no hdmi signal from your device'.
