Non-HDCP Compliant Error

Some TV's & cables are not HDCP compliant . Sometimes you can replace the cable to fix the problem & other times you have to replace the tv because its not HDCP compliant . First check to see if your tv is HDCP compliant .

look on ebay for an adapter try "HDCP to HDMI adapter" as a string i wont look but i can bet your not the only one
and some guys are good to solve simple wires and balance issues

HDCP: High Definition Copy Protocol

as far as i can tell this monitor is not HDCP compliant ( High Def Copy Protection ) and therefore will not be suitable as a TV monitor. Computers can use non HDCP compliant monitors but TV Tuners, Satellite Receivers, DVD players etc with HDMI are HDCP compliant and must have a HDCP display... HDMI has two formats basically HDCP and non HDCP

This piece of information should solve your problem:

High-bandwidth Digital Content Protection (HDCP) is a form of Digital Rights Management (DRM).
There is a licensing body that issues licenses for HDCP devices. Each HDCP-compliant device, like your Blu-ray player or Xbox, has a license and the ability to talk to the receiving device on the other end of the HDMI cable. The outputting device says "Hey display! Are you HDCP compliant? Here is my license, show me your license!" The display (or other HDCP compliant device) returns with "Why yes, I am legit! Here is my license!" When that process works, it happens within a thousandth of a second and you, the consumer, never even notice. You power on your Blu-ray player or DVR, it makes nice with your HDTV, and you live a happy life never knowing what HDCP even is.
if you have an older HDTV set that is not HDCP compliant then you cannot watch any HDCP compliant content on it. If you plug in your HDCP-compliant device to a non-compliant device, you'll either see a blank screen or an error message like "ERROR: NON-HDCP OUTPUT," "HDCP unauthorised," or simply "HDCP ERROR."
Short of buying a new television or giving up on your video game project the only way to deal with your HDCP compliance problem is to buy a cheap HDMI splitter that ignores HDCP requests.

WOW. I just experienced the same thing. None of my HDMI ports are working, though component is fine. I've had my unit since November 2007 and had no problems until this. I think the HDMI board has gone bad and will require replacing.

The HDMI cable was causing "Display connected non-HDCP compliant" error message to appear.
When I reconnected my DVD to TV using regular cable with 3 color connectors(i don't know what is the proper name for that cable) that error message no longer appears on my screen and I was able to watch my movie normally.

It appears that the monitor was designed to work with the display circuits and software driver on a Personal Computer. There is no circuitry in the display to handle the out put of DVD player. A smart TV has the circuitry. the display does not.

Hi Joey,
This is the my second HTS6510. I sent the first one back in August as it would not play the disc nor eject it and I'd only just got it. The replacement has worked well until recently when virtually the same problem you are experiencing happened to mine without "the contents cannot be displayed" bit. It corrected itself but did the same thing tonight and this time it sometimes displays the "content cannot be displayed" bit. I think it is the HDMI out connection that is at fault. Could be that it cannot cope with the sound, but I'm a long way from knowing how these things work. If you come back on site and know the answer please share it with me. I will be getting onto the seller in the morning as it's still under manufacturers warranty.
Cheers.
