I recently got a new monitor which I've been trying to set up to my custom built computer, which held no avail. It can connect fine to my old monitor, although once I attempt to connect it to my new monitor it doesn't want to work. These are all the same cables so they're most likely not the problem. I've tried 2 different cables and neither of them work on the new monitor, but do work on my old monitor. It's being connected via DisplayPort-DVI adapter.
