Z30i produces vertical lines on wake-up connected to Lenovo P71 Thinkpad

HP Recommended
Z30i Monitor
Microsoft Windows 10 (64-bit)

Monitor displays vertical lines on laptop wake up, resolved when I turn the monitor power off and back on, what is the cause? I am using HDMI for the source, also happens with Display Port as the source.


I also have a ZR30w, connected to a Startech KVM switch and there are no screen issues with either the laptop or my Lenovo P71 Thinkstation.
