Hi folks, I was wondering if I can get some help here:
*Problem Statement: HLN507W refuses to negociate a 720P resolution with a Nikon D90
DSLR and drops to 480P (D90 set to 720p).
*Equipment: HLN507, DVI-to-HDMI cable, Yamaha RX-V863 reciever, min-HDMI-to-HDMI cable, Nikon D90 DSLR.
- HLN507W displays 720P from multiple sources correctly (Yamaha receiver, Comcast
HDVR, LG Blue-Ray Player etc.) - excepts when connecting to the D90;
- tried different HDMI and mini-HDMI cables (price didn't made a difference to the
- D90 successfully negotiated 1080p and 720p using the same min-HDMI connected to
newer HD sets (Samsung LED series for example);
- tried connecting the D90 directly to the HLN507W using a mini-HDMI-to-DVI
cable/converter: same problem - 480p (Reciever not an issue).
- Samsung feedback: "its not the HLN507W issue as it can display 720p from other
- HDCP association: "doesn't look like an issue with the format/cables";
- Nikon: after 8 months of emails com. with Nikon Japan, I finally recieved some info. that
could make sense. Here is their last answer:
"The issue occurred probably because the D90 did not receive the appropriate extended display identification data (EDID) from the TV.
When a connected device does not indicate 1080i or 720p as its possible format in its EDID, the D90 outputs images in 480p format (minimum video format).
The function is designed so to avoid abnormal display of images on the TV.
If the camera outputs signals which are beyond TV capability, the images are not properly displayed.
Images are displayed on the TV in the format specified with your other HDMI sources, probably because those devices do not check the TV display capability when they output signals."
Does anyone know if the HLN507 supports EDID ?
Appreciate your feedback based on experience/knowledge.
Thanks and Happy Holidays !
