I have been struggling to get my lcd monitor to work with my HD cablebox. I tried single link DVI to DVI cable, and it wont work. Do I need to use Dual link in order to get it to work? My monitor supports HDCP, but I am not sure if that mean it supports HD signals. I am using LG L226WT monitor http://us.lge.com/products/model/detail/computer products_lcd monitors_wide screen_L226WT-BF.jhtml with this Scientific Atlanta 3250HD http://www.baldwin-telecom.net/cablebox/3250.pdf I am about to give up, but I decide to use the power of OT. Also, is there even a tuner card that supports HD signal?
