OK, my problem is this...Can I use my brand bew CPU with only an HDMI cable connected to my (old) monitor and my Motherboard MSI z170A Gaming M3? If yes, How? I tried the different settings in my monitor but it doesn't display anything. My motherboard doesn't have VGA so it is either HDMI to HDMI or DVI-D to VGA (But the case is, there is no cable like DVI-D to VGA). What should I do. One man said I should start it onboard but how? When I couldn't connect it to any monitor?? Thanks..
