At least your GTX 1080 GPU supports HDCP 2.2, and maybe your 4k monitor also.
Are you 100% sure that your 4k monitor doesn't comply with HDCP 2.2?
THX for testing.
@tgp7777777 Could you make further testing?
Maybe you have another monitor with Full-HD. This one certainly is
without HDCP 2
.2
Could you test here if decrypted UHD iso plays there, too.
Well it will at least Downscale to Full-HD, which itself afaik shouldn't be the least problem, if should work
without HDCP 2
.2 support anyway.
When you use external GPU like GTX 1080, it shouldn't matter in any case if CPU doesn't support HDCP 2.2 anyway.
But maybe I'm talking rubbish and maybe HDCP 2.2 doesn't play any role when AACS 2.0 of UHD-BD was decrypted or s.th. else removed which prevents HDCP 2.2 to get into place.
I'm just speculating. I just have a few old Core2 architecture computers (Xeon L5430 2.66 GHz quadcore, TDP 50W) system and only with Full-HD resolution monitor here at home.
My CPU is without HEVC decoder, and I don't have a GPU with HEVC decoding.
Playing 3840x2160 h.264? AVC or HEVC/h.265 youtube video at standard clock with CPU decoding has between 95-100+ % CPU usage.

Nearly fluently but sometimes ar heavy video scenes picture minimally slower than audio.
[Edit]Internet connection too slow &youtube Browser media player (Adobe flash) more inefficient
4k downloaded to mkv video seems to play fluently in MPV (with 3840x2160 to 1920x1080 interpolation), CPU overclocked from 2,66 GHz to 3,2 GHz and 96% max heavy CPU usage (at this video only)
[Update]
Did have FireFox running in background when playing 4k video with MPV. Did close FireFox and tested at standard clock. Max CPU usage here at standard clock (without) FireFox in background 90%.

I'm just curious if this system will play (theoretically) UHD directly from an decrypted ISO from an UHD friendly drive (besides my system is most probably a bit too slow)
Besides it must downscale the resoultion on my monitor anyway.

Damn I forgot bought an 3840x2160 IPS-Samsung monitor at other apartment. It has two HDMI ports.And one of the two HDMI supports HDCP 2.2 and 4K.
(And here was also 4k testing with 95-100+% CPU usage)
Let's see if it will play decrypted UHD isos on the UHD-Monitor-HDMI port with HDCP 2.2 and at the other UHD-Monitor-HDMI-port, too.
Got an UHD friendly drive (ASUS BW-16D1HT) manufactured in April 2017 with FW 3.01 preinstalled.
And if yes, when performance is too slow grab a GTX 1050 Ti, if we can rule out HDCP 2.2 stuff anyway.
