I've seen this topic a lot in these forums and in others. But I have yet to find a suitable resolution.
LN52A650 Samsung 52" LCD
AV-R720 Samsung Receiver
BD1500 Samsung Blu-ray player
Motorola something or other PVR
BD1500 (HDMI 1) and PS3 (HDMI 2) connected to AV-R720 via HDMI, which is connected to the LCD via HDMI into the HDMI 1 input.
The PVR is connected via Component to the LCD, and Optic cable to the receiver. The PVR is never an issue. As well, the blu-ray player is never an issue.
95% of the time, when I turn on the TV, and receiver, and PS3, the infamous "Mode Not supported" shows up. The rare times it doesn't, it seems like, is when the reciever is already 'warmed up' (having recently been set to the PS3 and working). When the message shows up, turning off the reciever and turning it back on always works. And more often than not, changing the TV input to something else, then back to HDMI works, but sometimes it doesn't.
Setting the PS3 to a lower resolution is not a solution. A 1080p capable TV should be able to display video from a 1080p source, no questions. It's kind of a waste of money to buy full 1080p samsung system, nly to reduce all the output resolutions to 720p. The system is all connected with high quality Monster HDMI cables.
Has anyone come up with a solution yet?
