Engadget reports HP introduced some green LCD displays. Pricing and availability is unknown.
That said, HP is quick to remind us that "white is the new green," in this case the low power, mercury-free, solid state White LEDs featured in the HP Compaq LA22f (22-inch) and HP Compaq LE19f (19-inch). Otherwise, the HP ZR22w (21.5-inch) and HP ZR24w (24-inch) are LCD displays with integrated 4-port USB hubs. All of these bad boys feature HDCP compliant DVI inputs, VGA, and optional USB graphics adapter for up to six simultaneous displays.
