Questions about LMP USB Typ C — DisplayPort

Thunderbolt 1 and 2 can only transmit PCI Express and Displayport signals. Only Thunderbolt 3 and 4 can also transmit USB signals and use the USB-C connection. This cable transmits the DP signal that is output via the Alternate Mode of USB-C. This has nothing to do with Thunderbolt. A Sandisk SSD has a USB interface and it can only generate USB signals. For true Thunderbolt, it would have to be able to generate PCI Express signals; otherwise, the Thunderbolt port will simply switch to USB mode. Basically, you can assume that Thunderbolt will only work if Thunderbolt compatibility is explicitly mentioned. What you saw is probably the difference between USB 3.0 (5 Gbit/s) and USB 3.1 (10 Gbit/s).

I suspect that this would not work. I would ask the manufacturer directly.

1440p should not be a problem. I assume you mean 144Hz. I suspect this is not the case. Especially the Mini Display Port. Devices that use such a port usually can't do 144Hz. It is best to use USB C to normal DisplayPort.

The combination of iMac (2012, with Thunderbolt) and HP Elite Notebook with Win10 did not work for me. I had to return the cable.

Normally, adapters only work in one direction. However, the whole topic is quite new and therefore information is very scarce, especially for your situation. The only indication I could find was a community comment for an Apple adapter that said he thought cables could be used in both directions, but not safely. Since Digitec now has a two-week return policy, I would just try it out (and ask you to report the results then. :D).
