Hi all. My HDMI (PC) to DisplayPort (monitor) cable doesn't work. Is there any way to make it work? Any ideas why it doesn't work? I mean, I know that HDMI works, and DP works, but HDMI to DP - doesn't. How come? I would really like to learn why. And more importantly, how to make it work. The monitor is HP EliteDisplay E221i (DP), if that matters, and the computer - some old Dell laptop (HDMI). I need to make it work, to connect, because I need the 2nd monitor (2 external monitors, with built-in monitor disabled scenario), and this is the only way to connect it.
