In 4K gaming hdcp has zero impact on what you can or can't play. You only care is having HDMI 2.0 or better for 4K60hz. Only when streaming/UHD blu-ray at 4K does HDCP 2.0 vs 2.2 become part of the conversation...so you have no need to worry if your gaming only on your monitor.
Is HDCP 2.2 required for 4K gaming? Or is that for only 4K movies and streaming services?
Only when displaying content from protected sources (a blu-ray, netflix, or for some reason just using the ps3)
Because I'm getting the Samsung U32H850 monitor for the Xbox One X, now there's been mixed reviews about the monitor supporting HDCP 2.2 or not, but "if" it doesn't, would it be a problem if I'm only playing 4K games and not watching 4K content from Netflix or any other streaming services?
