hdmi to dvi compatibility


I have a Lexicon RT 20 w/ hdmi outputs and an Leowe Articos HD55 with a dvi input. No digital signal is transfered between the two devices in 720p mode (or any mode for that matter). 480p component (analog) works fine. Any advice on ways to resolve this apparant hdmi to dvi incompatability? Intuitively, one would think the digital video would be passed w/o issue to the DVI.

Go with component video. Save a lot on cables and it is doubtful that you will see a difference.
All the high def sources must be HDCP compliant. If they are not you cant pass a digital video signal using a DVI or HDMI connection. You can only get 720/1080 by using an analog 3 cable component, 5 cable RGBHV or a RGB/RGBHV 15 pin D-SUB connection.
Thank you for your response. I am not familiar with accronym DRM. What does it refer to?
Digital Rights Management. I believe it gets used as an umbrella term for copy protection of digital media.
