I have a late 2009 27inch iMac and I would like to use my Samsung TV (Model #UN32EH5000 32-Inch 1080p 60Hz LED TV) as a second display. The resolution on the Samsung TV is set to 1080p yet the picture is not as crisp as on my iMac Display. Any idea on how to fix this so that both screens are identical in image quality? There doesn't seem to be a "PC input" on the Samsung TV, just 2 HDMI ports.
