Only one of my USB downstream ports by the headphone jack work. The other does nothing. I've tried several devices, won't power lights on headset or keyword. Pricey display to not work out of the box.

Did you remember to connect a USB 3.0 Upstream cable from the AW2518HF to the PC? I don't think DP is sufficient to power all of the AW2518HF USB downstream ports.
