The bridge should not care what kind of device is there on the other end. The bridge just has an output, going to another video component. >> Well, I can't say about this particular bridge, but afaik you can >> connect a parallel RGB signal to multiple panels just like that, without >> any muxing. > > Right, but in that case you're not reconfiguring the signal in any way > for each of the panels. You send one single signal to all of them. For Yes, that's one use case, cloning. But I was not talking about that. > all intents and purposes there is only one panel.

I was talking about the case where you have two totally different devices, let's say panels, connected to the same output. One could take a 16-bit parallel RGB signal, the other 24-bit. Only one of them can be enabled at a time (from HW perspective both can be enabled at the same time, but then the other one shows garbage). Tomi
