I have a question regarding the use of multiple displays, say, four, and each can display various maximum resolutions between 1080P and 1024x768. If the source device is outputting 1080P resolution and the highest native resolution display is also 1080P while the lowest resolution display is 1024 x 768, what will happen? Will the output device dumb down to the lowest common denominator for all devices, or will each device receive and show the highest resolution possible for that display?

Pretty clear question. Anyone from HDMI care to step up and clarify? It's only been six months since asked.

I have the same question. Would love someone from HDMI to answer this. I have had input from a few HDMI DA manufacturers but nothing satisfying.

Please see my thread the preview monitor question

The display devices advertise their capabilities through their EDID ROM. There are plenty of 720p devices that can accept 1080i signals, for example.

So, the answer to your question is this: An HDMI transmitter will only send out one video stream at a time, at a resolution equal or less than the highest supported.

Yes, the output will be "dumbed down," as you put it. If all the displays are HDTV's, it will probably be dumbed down to 720p.
