Display port version

[CodeRogue]

Greetings,

The DisplayLink I am using is Toshiba branded, and unfortunately, they were useless
when trying to get any information from them in regards to the unit.

Can someone please tell me :
1) What Displayport version is on the DisplayLink 4K,

or

2) Tell me how I can find that information?

I am wanting to order a second monitor for my configuration, but my understanding
is only DisplayPort v1.2 will support a daisy chain configuration vs. using the displayport for one monitor, and using DVI for the other monitor.

Thanks for any information you can provide.
Cheers
