So building a new rig and this is what I had to start with: GIGABYTE B450M DS3H AMD RYZEN 3 2200G CORSAIR VENGEANCE LPX DDR4 3200 (2X 8GB) SAPPHIRE NITRO+ RX 570 4GB first boot up had no displays, tried different set ups such as 1 ram stick, only on board gfx etc no luck. Realised the ram sticks weren't part of supported list so bought the HyperX version that was on the list and tried the same different set ups and I still have no display. Should I resign to it being a bad mobo and get a replacement? Alternatively, could it be the monitor? I got the Acer KG221Q but have also had my original Sony monitor and had no luck on either.
