NUC8i7HVK Video Issues

[MGros5]

I received and configured my NUC 8 yesterday, installing Windows 10 and all of the latest drivers and BIOS (Problem began before BIOS update). Everything appeared to be working well until the monitor went into standby after 30 minutes. When I moved the mouse the monitor came back on and the video was distorted and flickering, sometimes going to a green screen. The only way I could clear it up was to reboot the machine using the power button on the NUC. I attempted to wipe and reinstall both the AMD and Intel video drivers but had the same result. I later decided to change the settings so the monitor would not go into sleep mode and I would instead just power down the monitor. When I later turned on the monitor I was surprised to see the same issue. The video was flickering and I again had to reboot the NUC to restore stable video output. I'm running @ 3840x2160 @59 Hz and I have also set it to 60 Hz via Windows and it is connected via HDMI, no adapters are in use and the monitor and cable is confirmed working with other devices. This has already become very annoying since this machine will now be used as my desktop replacement. On a side note it seems the audio is not as clear as it should be. When using the front audio port I've received reports by the remote users that my mic has a bunch of background noise even when the room I am in is silent. It seems like this is a driver related issue so hopefully a resolution isn't far off.

Scan results attached.

The issue occurs on both front and back ports. I've currently connected my monitor via DisplayPort and so far I've not experienced any problems. However, I would like the option to use HDMI in the future since I will be adding multiple monitors to my setup.
