Just call your cable TV company and ask for a digital HD cable box.Most cable companies like Time Warner, Comcast, Cox, Cablevision, etc. all offer free upgrades to an HD cable box.These digital HD cable boxes usually have either a DVI or HDMI output port, which you can connect to any HDCP-compliant LCD Monitor. (Yes, DVI is compatible with HDMI). This works most of the time.If by some chance this doesn't work, then start thinking about spending money for a converter or something.Hope this helps.
