ISSUE # 1: If I click a movie's page on Amazon Prime, display goes blank every time. Screen shows "No signal detected". It won't display anything again until I Shut Down/Hibernate the NUC. Removing the HDMI cables or turning off TV won't solve problem. I've noticed this only seems to happen on sites with DRM content. A few examples are: https://www.amazon.com/gp/video/detail/B0748NJY1B/ref=pd_cbs_318_2 1, https://www.amazon.com/gp/video/detail/B01IG0E1F0/ref=pd_cbs_318_6 2, and https://www.amazon.com/gp/video/detail/B01LXFBBNV/ref=pd_cbs_318_8 3. Tried GFX update version 18.104.22.16836 and same problem. Currently experimenting with 22.214.171.12460, but it's just as bad so far. It appears the only way to ensure the display doesn't go blank (in FireFox) is to disable the Widevine Plug-in. But then Amazon won't allow movie streaming at all. To watch a film, I must enable DRM/Widevine, Hibernate, Power back up, then the page suddenly works fine until I click away. What leads me to believe this is a NUC graphics issue is that it happens regardless of browser, and only on my 4K display. NUC also completely froze up on YouTube videos a couple times. None of this happens with my 1080p display connected. Nor does it happen when my 4K TV resolution is set to 1080p. Any suggestions? I'm currently awaiting response from Amazon also.
ISSUE # 2: HDCP 2.2 devices not recognized by Amazon (again) at 4K 60Hz. This issue occurs no matter what version graphics firmware I use. But if I decrease the display frequency to 30Hz, HDCP videos suddenly work as they should. And again, they also work fine if I decrease the 4K TV's resolution to 1080/60. I'm hesitant to believe this is proper functioning.
I'm pretty certain the two issues are related through the Pro 580's processing of 4K graphics, but not sure how/why. If anyone knows of other websites with CRM/HDCP 2.2 mandated videos where I can compare to Amazon, I'm all ears. Don't have access to NetFlix though.

My apologies; things got hectic and I just now was able to view the past few messages. Didn't know you had linked to a new driver.
I'm no longer able to test out the NUC6i7KYK because I now have a different PC. Should I close this post as "resolved" or would that
mislead anyone with a similar issue hereafter?
Thank you for your response.
No problem at all. I will proceed to close this request, and if another member needs assistance, even when the issue is similar, we recommend to create a new thread because the equipment and setup may even differ. I will proceed to close this as resolved then.
