I bought new laptop HP with the mentioned graphic card in the subject and the lap top has no OS so I have win 8.1 but when I try it with the HP i found for the UEFI reasons I have to buy win 10 where I bought in the sale win 10 RS3 and update it. the version now 1803 (OS Build 17134.472)
when I play darsiders1 through HDMI to TV at full screen the sound on TV don't work and after a lot of googling the window mode screen works why?
all other App sounds work well as full screen video playing
my 5 years old Dell laptop with window 8.1 and graphic card AMD Radeon™ R7 M265, and all same external devices like same TV and same HDMI cable same wireless mouse and keyboard works well
