I recently bought a blu-ray player. My laptop has an HDMI port, but when I attach the blu-ray player using HDMI cable, nothing happens. My computer does not seem to know it is even there. Is the HDMI port broken? Or is there a secret to getting the computer to recognize it? Thanks for any insight/help. I'm usiing Windows 8.1, my laptop is a Toshiba Satellite C55D-A, and my blu-ray player is a Samsung BD-HM51. I also downloaded and installed a driver/update from Samsung.
