Thunderbolt question

[Prodo123]

If the ATD doesn't support Mini DisplayPort daisy-chaining, how about the one on the MacBook Pro?

If the ATD doesn't support Mini DisplayPort daisy-chaining, how about the one on the MacBook Pro?

I'm not sure anyone knows, and I've not heard of a display port 1.2 monitor with chaining support being on market yet for anyone to be able to test with.

And the reason the ATD doesn't is a technical limitation of the thunderbolt chipset, as shown by anandtechs comprehensive review of the display, each chip can only separate one displayport stream out of the thunderbolt traffic, leaving the rest to be forwarded on, still as part of the thunderbolt traffic, rather than as a raw display port input, hence a display port adapter doesn't working directly though the display, but does though another device chained that doesn't extract the display port output for it's own use.

Apparently there is this weird config.
MBP <-> ATD <-> ATD //works with all MBPs according to Apple
MBP <-> ATD <-> DP Display //doesn't work
MBP <-> ATD <-> someTBdevice like the Paragon raid thingy <-> DP Display //works

The reason is probably because Apple wants you to buy more ATD and throw away all your old DP Displays and polluting the environment more by advertising the way of a throw it away and buy new culture.

I guess at some point they might release a FW upgrade that ends this limitation again.
