Is Panasonic projector PT-LB20U compliant with HDCP?


Since the PT-LB20U only has VGA, S-video and composite video inputs, it isn't HDCP compliant. You would need a device with DVI (sometimes), HDMI, or DisplayPort inputs. See page 15 for the connections available on the projector.

Panasonic has the manual for the projector on the product page: http://shop.panasonic.com/support-only/PTLB20U-EC.html . The direct link to the manual is http://service.us.panasonic.com/OPERMANPDF/PTLB20NTU.PDF .

I wish that I had better news for you.

(the high definition copy protection details require the digital video signal capabilities of the newer inputs. Most digital to analog converters (HDMI to VGA, for example) do not support HDCP.)

Distorted picture.


Is the menu text clear on the screen, when it's focused correctly. Or is that also distorted.
If the menu text is OK then the picture signal is dodgy. could be due to a bad earth lead on the video cable.
Is it distorted on all signal inputs
