I am running Windows 10 with two monitors (in extended mode): U2713HM and U2413. While playing a Blu-Ray, the U2413 shows up as HDCP compliant and will play the Blu-Ray content. The U2713HM shows up as non-compliant for HDCP and will not show the Blu-Ray playback. The GPU is an Nvidia GTX 660 Ti. One monitor is on the DVI-I and one on the DVI-D. I have swapped the monitor DVI ports to no effect. I have tried the U2713HM individually on both DVI ports and changed the resolution from (2560 x 1440) to (1920 x 1080) or (1920 x 1200), all to no effect. Both monitor drivers are up-to-date, although the driver for the U2413 is newer (9/7/2015) than the driver for the U2713HM (8/8/2012). 

Thank you for the help!
