Displays reset frequently in Dual Monitor Mode

[OKSnoey]

Config: HP Envy Notebook with Intel Core i7-5500U running Windows 10 Home 64-bit. 16 GB of 1600Mhz RAM

Running extended display with 2 hp ZR24440W Displays (1 connected via HDMI and the other via DVI). The HDMI is connected directly to the notebook (have tried it both ways). The notebook display is usually disabled.

The issue is that the displays frequently go into bouts of resetting. During these periods the resets occur approx every 20 seconds.Between bouts things seem relatively calm.

I have gone through the DisplayLink checklist. All drivers (USB, Monitor, graphics, DisplayLink, ..etc) plus Bios are up-to-date. I've checked the cables. The monitors work fine independently. It also works fine with just a single monitor (either one) plus the notebook display in extended mode. I've also disabled the USB power down timeouts.

I've attached the Zip file output from the DisplayLink tool in the subsequent entry below
