I have a problem with getting both HD sound and picture (720p) in my HT, based on Sharp XV-Z2000 projector.
The following components are employed:
1) Sharp XV-Z2000 DLP projector, DVI-I input, HDCP compliant, 720p max. resolution, component video input;
2) NAD T748 receiver with HDMI ports (v.1.4a), HDCP and ARC compliant;
3) NAD T567 BD player witn HDMI (v.1.4a) and component outputs, HDCP and ARC compliant;
4) High quality HDMI splitter 1x2 (v.1.4a), HDCP and ARC compliant;
5) High speed HDMI cables (v.1.4a), ARC compliant; proper HDMI-DVI adapter.
All the components were tested with Full HD plasma TV and proved to be fine, delivering HD sound and picture (1080p).
I have tested the following connection patterns:
1) BD player - Receiver - Splitter - Projector & TV
Result: HD sound, no picture; TV disconnection did not help, the projector says No signal;
2) BD player - Splitter - Receiver & Projector
Result: HD sound, no picture; the projector says No signal;
3) BD player - Receiver - Projector
Result: HD sound, unstable 720p picture: 2-3 min then black screen for 10-15 seconds and over again;
4) BD player - Projector directly through HDMI, BD player - Receiver directly through coaxial ports
Result: stable 720p picture, regular DD/DTS sound (not HD as expected, HD sound channelled through HDMI only).
Conclusion: the projector cannot stand any additional component in the signal chain.
Have anybody faced the same problem connecting an old projector to HDMI equipment? Probably, some tricks might help. For instance, my projector wants to be turned on first, otherwise it does not see the BD player.
I have also tried video component line from the player to projector, but the resolution fell to 540i on BDs, however, showing 540p on DVDs. I believe it is HDCP issue, as BD player set-up promises to deliver 720p through video component output. Thus, this option does not help.
Sorry for the long story and thank you for reading. I just want to exclude obvious follow-up questions and save your time.
I would very much appreciate your ideas on how to fix it, if at all possible. Though one way I already know - projector replacement.
