I have a HP w2071d monitor, and when it turns on all it says is "no signal found", or "monitor going to sleep". I have tried to use a DVI cable to connect my monitor and my graphics card, and I have tried using a DisplayPort to VGA adapter, and neither of them worked. In case it is relevant information, I have an Asus Prime Z370-p motherboard and an intel i5 8600k. Is it something as simple as, my monitor and graphics card aren't compatible, or am I missing something here?
