I scored an XPS One at a great price. It has hdmi input but I can't get my gaming laptop to display at the monitor's native resolution when using the hdmi input. If not...it's ok, but I plan on building a new gaming rig and want to use this as the monitor when I want to game at this resolution. Is this possible? I was under the impression that trying to pump this resolution required a dual link DVI cable. Do those tie into one dvi or hdmi cable at the other end? Any advice is appreciated.
