Yes, connecting any HDMI device (including consoles) to a Hazro HZ27WC is impossible. You need the HZ27WD for that as that's the 'connection rich' model.
There are options, but far too costly for a simple test. You'd need something to upscale HDMI to 2560x1440 and output it over dual-link DVI, iirc there are solutions that do this but the prices are in the £3000+ range.
If your laptop has an expresscard slot it's possible to use a desktop graphicscard. Costs, a ~$80 PCB + the costs of a powersupply and videocard (~£60-80).
