You might see video or movie in reduced resolution on your HDTV or monitor. To play a DVD, an HD-DVD, or a downloaded movie in high definition, the High-bandwidth Digital Content Protection (HDCP) protocol is required. But all TVs, monitors, or adapters don’t support HDCP. So, you have to ensure that your HDTV supports HDCP. You’ll get more info at your TV user manual. DVI ports don’t support the HDCP protocol. You cannot use a DVI port and adapter to connect an HDMI cable to your console. You can try another cable, such as an Xbox Component HD A/V Cable or a VGA cable.
