The PN-S525 is a 52-inch monitor and features an 1800:1 contrast ratio and 6 ms pixel response time.  The color and brightness have been improved, extending the viewing angle to 176 degrees.  The LCD contains DVI-D, Component and RS-232C inputs.  A little late to the game, but Sharp is adding an HDMI input, only one.  The monitor also features an RJ-45 LAN port for Internet connectivity, making updates easy.

The PNS655 65-inch monitor has much the same specifications as the 52-inch.  There is an increase in apparent contrast ratio to 2000:1.

The 52-inch monitor is available for an MSRP of $4,550, while the 65-inch is available for an MSRP of $10,795.
