Apple Thunderbolt Display to a PC?

[oscarpetre]

Hi!

I'm asking for a friend who inherited a Apple Thunderbolt Display, A1407, and trying to connect it to his laptop PC, a Power G8 Mobile Workstation. It seems to have Thunderbolt 4, and he have tried this adapter (A1790), but it doesn't work. Is it wrong adapter, or what should he do? Any tips?

Thunderbolt 4 ports may or may NOT be Thunderbolt 3 enabled.
The A1407 monitor needs a Thunderbolt signal to work - which can come through the A1790 adapter.
An Apple Thunderbolt 4 Mac also passes TB3 signals through, so will work with an A1407.
Some PC's can also do this, most can't ( as this saves manufacturing costs).

I don't see TB3 output mentioned in your HP computer's specs, so it looks like it only passes USB-C Displayport 1.4 video out.
Which isn't compatible with either A1790 or A1407 devices.

Thanks! So no other adapter to try? I will have to persuade him to get a Mac

Practically speaking - it'll either work with the A1790, or it won't. If it doesn't, it's not practical to use it.
