Windows 10 HDCP Errors in multi-monitor configurations - Microsoft Community


i've been having issues past few months can no longer play blu-rays on windows 10 desktop due hdcp errors.  at first thought due swapping monitor cables, have since discovered seems new "feature."  i have 3 displays on system, 2 of both 1080p/hdcp-capable , configured mirror each other.  

if either of these monitors off, hdcp-checks fail.  it appears windows isn't disabling hdcp-check displays configured not powered-on/active.  

this same configuration worked me on summer without needing have both displays on.  my best guess broke sometime around big 'anniversary update' installed.  

i found user similar issues on http://superuser.com/questions/1118587/hdcp-error-on-dual-monitor-when-one-is-turned-off  that user experiencing issues amd radeon video card, while have nvidia card.  

hi,

to address concern, let's try perform clean boot on system check if drivers updated. this, visit links below:

let know how goes.

regards.
