I was faintly surprised that my recent monitor purchase came with a displayport cable.
Didn't help connecting it to my Macbook, but still..
Don't most monitors ship with DisplayPort cables? All of mine have. HDMI is more popular with TVs/home theater systems.
DisplayPort has been running the best PC high end monitors for a long while. HDMI OTOH has been in A/V land (DRM management).
