I've had the monitor for a while, and ran an older tower on it, along with a Yoga Pro 2, and Macbook Pro Retina. Quite a learning curve to get the best resolution, but finally was able to get it with all 3 once I learned about the right adaptors and cables to use. this new tower does not have either a displayport or dual link plug on the back. Either one of those 2 were on my old tower and worked well. Is there a way to get it with only a hdmi or vga plug-in?
