I got fed up with the "is the ALIS screen HD compatible??" question, so mailed them and got this: Dear Sir, Thank you for your email. I can confirm that the ALIS Screens used are HD compatible. The Alis screens can output 1024 lines for each frame. I believe the confusion is occurring due to ALIS being interlaced. This means it will output 512 ODD lines and then 512 EVEN lines, making a total of 1024. The plasmas also meet the EICTA standard. You will see the HD Logo on Brochures etc, but note that the panels are not sold with the HD logo sticker on it. I apologise for any inconvenience or dissatisfaction this matter may have caused you but trust that the above information has helped to clarify the situation. Regards Consumer Affairs Team Hitachi (Europe) Ltd England, UK. Doesn't tell us anything new, but does explain why no HD logo So to sum up, it's HD Ready.
