Dell monitors not functioning with Targus ACP70USZ, Win 10

[HamaLamaDingDong]

I have a Targus ACP70USZ with DisplayLink that has functioned flawlessly for over a year. I left my PC on overnight (my normal practice) and when I started work this morning, the monitors no longer get any signal from the docking station.

I've verified that everything has power, and I've connected my laptop individually to each display to verify that both the laptop and monitors are functional. All the USB ports on the docking station appear to be working (webcam works fine, for example).

I updated the DisplayLink driver this morning, but that didn't help. I installed the latest Windows 10 update on 7/12 and everything has been working fine since then. Laptop is a Dell Inspiron 13-7359.

If there is supposed to be DisplayLink software running somewhere, I can't seem to find it. Nothing shows up under 'services' or device manager. Ideas?

Thanks,
